Bug
I tried to use the template on the Sandbox, and it had a bug. It said Code Error. The command "command1" does not work David Dylan (talk) 23:04, 22 January 2017 (UTC)
 * The problem appears to be that previewing  gives error "The time allocated for running scripts has expired." The documentation at wikidata says that   should work, but it gives the same error. If you see some other error, please post the wikitext that was used and a copy of the resulting message. Johnuniq (talk) 00:23, 23 January 2017 (UTC)
 * The problem is the following code:

function p._label(args, _) -- ...   while _:processFlag(nextArg) do        nextArg = mw.text.trim(args[nextIndex] or "") nextIndex = nextIndex + 1 end -- ... end
 * The  function returns true if   is an empty string, and that gives an infinite loop. A cleaner way of processing the arguments is needed.
 * While finding this, I noticed
 * in . Possibly the intention is that a module could call   and pass a table of arguments, but if that occurred, the above would give a run time error because   would very likely be nil, so calling it would fail. Using Module:Arguments might be easiest, although I find it confusing—see Module talk:Arguments. Johnuniq (talk) 01:26, 23 January 2017 (UTC)
 * Thank you for reporting this bug. I've created a fix for it. The problem was introduced when I started allowing empty flags, without thinking about what this would do with the call to . Needless to say, it was not thoroughly tested.
 * Regarding : if   returns nil, then the   will assign the current   instead, so I don't think this is an issue. I've copied this piece from another module. Nevertheless, I will have a look at Module:Arguments as you suggested. Thank you.  Thayts   •••  21:15, 2 February 2017 (UTC)
 * The point is that another module might call  in this module, and the other module would pass   which is a table of arguments to specify what is wanted. Because it is just a standard table, it will have no   member so when this module tries to execute   it will be trying to call a nil value, and that will result in a crash. Module:Arguments does a bunch of tricky stuff so it works with a frame or a table. Unfortunately it requires rather unappealing procedures. Johnuniq (talk) 05:00, 3 February 2017 (UTC)
 * I see. The  function is not meant to be called by other modules, however, but by templates. Modules should call the functions beginning with underscores   directly.  Thayts   •••  05:59, 3 February 2017 (UTC)
 * OK, I was just guessing about the intention of using . If it is assumed  is called as the result of using   (either directly or via a template), there is no way   can be nil. The nil result only occurs if a module calls   twice (that is, if a module attempts to get the parent of the parent). I would have to set up a sandbox with a test to prove that but I believe I convinced myself that is how it works when starting on Lua. Johnuniq (talk) 07:01, 3 February 2017 (UTC)
 * Without the  I have had situations where it didn't work. But the module has changed a lot since then so I'm not sure if it is really necessary. I think I will test a bit again without it.
 * By the way, even if the parent of the parent is nil, then the  will always assure that that nil value is never assigned.  Thayts   •••  16:04, 3 February 2017 (UTC)
 * I haven't looked at frame/parent stuff for a while so I made some tests. See User talk:Johnuniq/temp which displays the results of calling a template which invokes a module, and directly invoking the module.  is only nil when trying to get the parent of the parent. Johnuniq (talk) 05:54, 4 February 2017 (UTC)
 * Your example helped me understand how it works. So yeah, I definitely need the . The   function is just nothing more than a necessary evil, so that things like templates can actually call the other functions. If you are able to call one of the other functions directly, then you should. Only use   if you have to. The only use case I currently see is the wikidata template, for which one would expect that arguments passed to that template are the actual arguments that will be used. Since a regular template does not take any arguments from any parents either, I'd like to keep it simple and mimic that behaviour, not worrying about arguments passed by other parents.

Reference names
Hi there. Is there a way to define the names (as in ) for the references imported from Wikidata, so that we can avoid having duplicate refs in articles where they have been locally defined and defined on Wikidata? Thanks. Mike Peel (talk) 15:08, 29 January 2017 (UTC)
 * Hi . No, not at the moment. However, references that have been imported from Wikidata using this module more than once on the same page do have a common name and will not be duplicated. Thayts   •••  21:23, 2 February 2017 (UTC)
 * Hi I've been testing this at Juana Rosa Aguirre, and it seems to be working nicely. However, in most cases the reference will already exist in the article, and it's not good to have duplicate refs. I don't suppose something like  could be used to define the names of the refs so that we can avoid those duplications? Thanks. Mike Peel (talk) 21:40, 3 February 2017 (UTC)
 * The problem with that is that there is no reliable way to say which reference imported from Wikidata should get that name. A claim in Wikidata can have more than one reference, even stored in arbitrary order, namely. The names this module is currently assigning to references are hash values that are (or are supposed to be) unique per set of properties that make up one reference. You could perhaps propose to make it possible to replace a particular hash value by a custom value in this module's output. You could also do it the other way around: hovering over the footnote number of a reference returned by this module to see its name (in this module's case it starts with "wikidata" followed by a hash value) and then assigning that name to the already existing reference. Yet this still isn't reliable, since details of references on Wikidata are subject to change and will cause the hash value to change too as a result. What is reliable is to replace the already existing references with the ones imported from Wikidata using . Would that work for you?  Thayts   •••  16:54, 5 February 2017 (UTC)

Substing Wikidata
How would one go about using subst: functionality with Wikidata?--Pharos (talk) 04:44, 10 April 2017 (UTC)
 * See Template:Convert for what is needed in the template. Johnuniq (talk) 05:52, 10 April 2017 (UTC)
 * Convert uses subst technically, yes, but what I want to do is actually substitute the output in plain wikitext, like have "Douglas Adams" be viewable under 'edit source' on User:Pharos/sandbox.--Pharos (talk) 15:13, 10 April 2017 (UTC)
 * user:Pharos, that's what he meant too... diff. --Jeremyb (talk) 18:06, 10 April 2017 (UTC)
 * Oh, thanks for that diff which shows that  → Dutch (and two other examples). It seems it is possible to subst wikidata but I assumed from the OP that something bad happened if you tried. Convert used to be broken when substituted before the magic   was inserted into the template. Historians can see the addition in the history of Convert/sandboxlua which followed this VPT request.

Merge duplicate refs?
E.g. at Liverpool Maritime Mercantile City, the references for the criteria in the infobox are duplicated three times, since there are three entries for the property on Wikidata each with the same reference. Can the three be merged together rather than appearing separately, please? Thanks. Mike Peel (talk) 00:18, 1 May 2017 (UTC)

Is it possible to include vertical bar in format text?
I'm now trying to shorten the very lengthy template Module:Infobox gene by using this Wd template, at my personal space. This is very useful. Thank for your great code! My question is as follows. When I try to include vertical bar "|" in format-defining text, it doesn't work well. Even when I add escape "\", it is simply recognized as a separator (sample diff). If it worked well in that diff, I could get three "RNA expression pattern" graph images just like that in the infobox at the right, but it didn't work. Is there any special way to include vertical bar? --Was a bee (talk) 03:03, 3 September 2017 (UTC)

Using Cite Q?
In cases where the reference is pointing to a separate Wikidata entry with bibliographic information, would it be possible to fetch the reference info from that separate Q-number? Something like Cite Q does, e.g.,. Is it possible to detect when only a Q-number is returned, and auto-call Cite Q in those cases? Thanks. Mike Peel (talk) 23:12, 7 July 2017 (UTC)
 * I've implemented a call to Cite Q. It is only used if is the only bit of information in the reference statement. Cite Q seems to be in beta itself and I think in the future both calls to Cite Q and Cite web should be replaced by a call to Citation.  Thayts   •••  20:11, 8 July 2017 (UTC)
 * That's fantastic, thanks! There are some errors coming up, but I think those are issues with the cite Q template so I'll report them on that talk page. I'm not fussed about the citation style so much as getting the data shown, but I'm sure other editors will start discussions on those at some point in the future. ;-) Thanks. Mike Peel (talk) 20:58, 8 July 2017 (UTC)

Instead of hard-coding the template names for Cite web and Cite Q into Module:Wd/i18n, would it not be better to just use Wikidata for this? For example using mw.wikibase.sitelink on and. Then there is less to localize. 50.53.1.33 (talk) 17:16, 5 September 2017 (UTC)
 * That's a nice suggestion. However, the parameters may be called differently on other wiki's as well and would still need to be localized. Thayts   •••  19:07, 5 September 2017 (UTC)
 * I was not suggesting there would be nothing to localize—just less. I do not like maintaining multiple sets of the same data. When possible, I find it better if there is one origin for data and everything uses that. 50.53.1.33 (talk) 21:36, 5 September 2017 (UTC)

Aliases and format
Hello again! I’m sorry to bother you, but I would be grateful if you could think about these 2 things.

1. Alias fetch command (d:Help:Aliases). For example,  and   like "property" and "properties" commands.

2. Processing the output from "format" as wikitext. If evaluating "format" text as wikitext just after the replace of %p by value, I suppose it would make possible to use template, magicword or #if-text in "format" text.

I don't even know whether these things are possible or not, whether Lua thing or Mediawiki thing. If I am pointless, please forget about this! Thanks! --Was a bee (talk) 10:35, 17 September 2017 (UTC)
 * I think my explanation about second part was not enough. So I put example. Although this is just an example, if getting data from d:Q21117967 by the following code, it works very well.






 * But if editor wants to modify the retrieved each values with template (for example Fixcaps), result is correct, but sad.

Recent edits
@Pppery: A lot of edits to Module:Wd are occurring. I see some also in Module:Wd/sandbox. Shouldn't pretty well all the edits be in the sandbox? The script errors tracking category (articles) is showing hundreds of pages, and I think that is from the recent edit which Thayts fixed (I'm currently purging the category so genuine errors can be found). At any rate, the module has 5811 transclusions so tweaks definitely should happen in the sandbox to avoid unnecessary overhead regardless of whether another glitch might occur. If wanted, I would be happy to remove the many global variables which are currently in the module. Johnuniq (talk) 04:41, 12 October 2017 (UTC)

P of Q
Not really sure whether this is the right place to ask, but here goes: I'd like a (simple) template that returns Wikidata claims given a Q number and a P number. For instance, the publisher of A Haunted House and Other Short Stories is Hogarth Press. The property number of "publisher" is P123. For the sake of this example, let's call the proposed template Wikidata/P of Q (other names are possible), then: or would return: Then, additionally, if no Q number is given, the template takes the Q number of the page on which it is, thus if the Wikidata/P of Q template is placed on the A Haunted House and Other Short Stories page, with only the first parameter (the P parameter) added, thus: or it gives the same return as mentioned above.
 * Hogarth Press

I suppose this could be done with the current Wikidata template, with the correct parameters — maybe such simplified template already exists, and I just didn't find it. Could someone help out here? Tx. --Francis Schonken (talk) 09:06, 5 November 2017 (UTC)

Unit symbols
I'm thinking about using unit symbols instead of unit labels (singular form of the label not appropriate for direct use + too long for infoboxes). Could you take a look: ? (It could be made optional and further optimized by saving wikidata calls via local array with the most common units.) --Nk (talk) 11:46, 12 January 2018 (UTC)
 * Yeah, I've been thinking about it as well. But the problem I saw was that you cannot know from the unit's Wikidata item if the symbol should normally be added in front of the value or behind it, and if there should be a space between it or not. And that might also differ per language. So I'm not confident enough yet that this can be done the right way in all cases. Thayts   •••  20:23, 12 January 2018 (UTC)

raw date format?
This returns a date in a format that does not accord with MOS:DATE:
 * → (P577 is publication date for: )

Is there a reason that month and day values in raw returns are rendered as single digit when less than 10? Technically this occurs because  returns numbers, not strings for year, month, day so leading zeros in the source from the wikidata raw time data are lost. If leading zeros are not omitted for a specific reason, one might rewrite line 1035:

and line 1038:

—Trappist the monk (talk) 19:06, 23 March 2018 (UTC)
 * I wasn't aware of MOS:DATE or that the current format would cause any problems. I think your solution is simplest to implement, but maybe we need to do the same for the year (although the MOS says yyyy-mm-dd should only be used with Gregorian dates; not sure what to do with Julian dates). Also, if the precision is for example "month" then in this case "2015-04" would be returned (if the leading zero is added). Is that sufficient, or should the digits for the day also be filled like "2015-04-00" in your opinion? (This is also how Wikidata returns it in string format, but I'm not sure if this is considered a valid date.) Thayts   •••  22:07, 23 March 2018 (UTC)
 * Perhaps I should do it like decades, centuries and millenniums, and return "2015-04-01" in that case. Thayts   •••  22:32, 23 March 2018 (UTC)
 * I'm presently wondering about a request to migrate the cs1|2 module suite and to Wikidata which rewrites dates according to the user's interface language setting before they are passed to the template and module.  Changing the interface away from English causes the date validation code to emit errors. For example, 29 April 2015 becomes 29 abr 2015 when the interface is changed to Spanish (made stranger by abbreviating the month name; why?)  Example at d:Wikidata:Sandbox.
 * I'm not really sure what the answer is. MOS doesn't like YYYY-MM dates because they can be too easily confused with YYYY–YY.  There was a time when cs1|2 considered adopting parts of EDTF to handle machine generated dates (citoid was the machine we were thinking about).  ISO BIS 8601:2016 part 2 (still underdevelopment) suggests a method for handling uncertain or unspecified date parts (2014-04-XX is one way it might be done).  At cs1|2 we did an experiment with a similar form that would correctly render incomplete dates.  Something similar could be done here.  Alternately, I suppose that the date precision from the raw wikidata timestamp could be applied so: 2015-04-29/11, 2015-04/10, and 2015/9.  Yet another alternately, the function could return precision as a second value:
 * where  for month precision dates would be YYYY-MM-00 (just like wikidata) or maybe, for compatibility with existing use (if there is any), return YYYY-MM.  Users can choose to ignore the second return.
 * —Trappist the monk (talk) 00:55, 24 March 2018 (UTC)
 * If it is relevant for the citation module at all, then it should accept some format for dates of lesser precision than days. Currently it doesn't accept "2014-04-XX", nor "2014-04-00", nor "2014-04". However, from "2014-04" it can be deduced that only the month of the year is known (provided that such a date format returned by this module will always mean YYYY-MM). Returning multiple values, either concatenated or separately, would be another possibility indeed, but that requires to do some deducing too. Returning them separately is certainly not compatible with templates that can only receive one value. I could of course work around that if necessary, returning single, concatenated values when called by a template and multiple otherwise, but that would require an overhaul of the current module. This is something we can discuss about, but for now I have made a change so that day-precision dates are always returned as YYYY-MM-DD as you suggested. Thayts   •••  12:37, 24 March 2018 (UTC)
 * Point. I was thinking 'module' so didn't think 'template' when I suggested multiple return values (and I was pressed for time).
 * Yeah, cs1|2 does not accept incomplete ymd dates any longer. That experiment did not gain sufficient traction (the form was YYYY-MM-uu from the edtf preliminary standard).  cs1|2 could probably support YYyy-MM dates where the values in yy and MM are, in combination, clearly unambiguous.  But, since MOS prohibits the YYYY-MM date form, it is easier to simply reject that date style.
 * I have implemented a stopgap 'fix' to the wikidata version of d:Template:cite Q that uses code suggested to me at d:Help_talk:Dates. I had been hoping for a more generic solution; something that would be usable regardless of where the template existed; perhaps something like  .  That functionality, I would think, should be available.  Apparently not.

Code for i18n
@Thayts: On 9 May 2017  was introduced. Do you have a reason to use that off-wiki? I believe it would never do anything useful in a Scribunto module ( would always be nil). Is the code used anywhere? That is, does Module:Wd ever get "included by other module" which passes the title in ?

The background to my question is that a discussion at VPT is questioning the use of red-linked /i18n pages. I haven't looked at whether this module is part of that but it is the earliest form of the code that I have seen, and its procedure was copied to Module:Wikidata in October 2017. In this October 2017 comment I mentioned "two really puzzling aspects of the code"—that is, two things which I believe would never work.

It is irritating to edit an article at enwiki and see a red-linked /i18n page. I was hoping to investigate whether there was some workaround that might disable that for enwiki while leaving it available for other projects. I'll look at that later but first I would like to understand the above. Johnuniq (talk) 03:36, 28 June 2018 (UTC)


 * First of all, the split between the module's logic and the i18n submodule was made to make it easy to copy over the logic to other wikis and to keep it updated without the need to tweak it for locality all the time. Since the module on other wikis might have a different title, especially in the namespace part 'Module:' (which is written differently in different languages), I was looking for a way to determine the local title (so that this doesn't need to be hardcoded and tweaked either). This is needed to actually locate the i18n submodule (the title "/i18n" is indeed a hardcoded convention).
 * For template inclusions this is easy, since you can get it from the frame. The problem is indeed when the module is included by another module, which I wanted to be possible (not sure if there is any module doing that with Module:Wd right now, but that doesn't really matter). In that case, the title contained by the frame will be the title of the module that is including Module:Wd, and so not actually the title of the included module "Module:Wd" which is needed to construct "Module:Wd/i18n". After some googling I found out that there is a triple-dot argument  that on Wikipedia, for reasons unknown to me, contains the title of the called module (this was the only solution I could find after also consulting the Wikipedia Lua community). But it only contains that title when the module is included by another module. Here is an example, where module number 2 includes module number 1 and calls   in module number 1:


 * As you can see on the bottom row, the  contains the title of the module that was included, which differs from the title of the module that was including it. I hope this clarifies things.
 * Regarding the red links, I'm not sure what causes it in the Infobox module and if it the  is part of the cause at all. Obviously, a /i18n submodule should only be called if there actually is one.  Thayts   •••  10:52, 30 June 2018 (UTC)
 * Amazing! Thanks for the comprehensive reply. It is reasonable as  provides the command-line arguments in a stand-alone Lua program (that is, not a module running in Scribunto), and those arguments include the name of the program being run. I do not see   documented anywhere as being available in Scribunto to get the name of a module called by another module with  . I will have to think some more and may ask for information somewhere.
 * Re "Module:" possibly being different at other projects, it's not relevant but in case you were not aware, "Module:" works everywhere, for example bn:Module:Convert and bn:Module:ট্র্যাক তালিকায়ন.
 * In a couple of days I hope also to think about the /i18n issue and see whether some trick might be used to disable the red link at enwiki (perhaps do not look for a subpage if the start of the  name is "Module:"?). Johnuniq (talk) 11:57, 30 June 2018 (UTC)
 * You're welcome. I do remember that I expected  to be a table and that it turned out to be a string instead (actually the string I needed). I did not know about the English namespace working on other wikis, good to know! Still, the name of the module might differ from "Wd", so it's good to leave it in there.  Thayts   •••  12:35, 30 June 2018 (UTC)
 * Some checking shows a slightly different picture from what I said earlier. In stand-alone Lua 5.1, the global variable  is a table containing the command-line arguments and a little bit more. The name of the script being run is   and any arguments are in ,  , etc. If used outside a function,   unpacks   which would generate  ,  , etc (but would omit the name of the script in  ). It looks like the place where Scribunto sets   is package.lua (that applies when one module uses   to access a second module). That sets   to the name of the second module.  Using   puts global   into local   which gets the desired result. Using   is convenient because it will give nil (if global   is nil) or  .  @Anomie: Is what I've said correct? Can we rely on   being nil (if a module is directly called with #invoke) or being a table with   being the name of the  d module? Johnuniq (talk) 07:24, 1 July 2018 (UTC)
 * You seem to be right. I've replaced  with   and it does contain the same string:


 * As the error shows, you would need to do an extra check to see if the global  is set, so   is indeed more convenient to use. Thanks for checking this out!  Thayts   •••  07:58, 1 July 2018 (UTC)
 * As far as existing behavior goes, you're effectively correct.  will be nil from an   and   will be empty, and from     will be a table having one element (the module name loaded) and   will be a list as described. If you want to get technical, note that   doesn't actually unpack  . It's just that the two contain the same values.  I'm also not sure why Scribunto's package library sets   in , it doesn't seem that standard Lua 5.1's package library does that. I guess it's because Scribunto's package library was originally copied from a compat-5.1 library for 5.0 and 5.0 doesn't seem to have any other way to pass the module name parameter in a 5.1-like manner.

Property
I've struck through "Property, used to add a Wikidata property link in text" because clearly Property is something else entirely, but I have no idea what it should list here; I assume there is some template for that purpose. - Jmabel &#124; Talk 23:43, 13 June 2018 (UTC)


 * Two templates can do that: Wikidata entity link (which requires the leading "P") and Wikidata property link (which works with or without the "P" and has additional display options). Also, Property is now a redirect to the second template (similar to d:Template:Property). I updated the list at . -- Zyxw (talk) 19:43, 1 August 2018 (UTC)

label in "references" with no slovenian language available
Hi from Slovenian Wikipedia! Can you help me with a problem?


 * Example: displays


 * Problem: The publisher "" does not have a label in Slovenian language, so text "publisher: Statistics Netherlands" is not displayed in Slovenian articles. Is it possible to display the label in any available language? You can see how it works at sl:Uporabnik:Pinky sl/PeskovnikW

--Pinky sl (talk) 19:22, 4 January 2019 (UTC)


 * Hi, you can set a Slovenian label yourself at https://www.wikidata.org/wiki/Q167086?setlang=sl&uselang=sl. That label should then be displayed. Thayts   •••  12:20, 5 January 2019 (UTC)
 * Thanks for your answer. Yes, I can set it. But I am in charge for importing data from Wikidata into our infoboxes. I am preparing the first infobox that will be filled completely from wd. And references are important. I cannot set all the missing sl labels; and labels keeps updating. And it is not just about publishers. --Pinky sl (talk) 07:44, 6 January 2019 (UTC)
 * Well, do you have a suggestion what should be displayed if a Slovenian label is not available? We could perhaps use English as default, but there is also no guarantee that an English label is always available. Thayts   •••  12:45, 6 January 2019 (UTC)
 * I guess, the best way to do this is: if local language label is not available, then substitute language shoud be used (maybe this can be set in /i18). If there is no local or substitute language, you can display just link to Wikidata object - example: Q167086? with an error category. It is better that way then leave it empty.

Most recent claim regardless of rank
Hi, I have another question: is there a way to return the claim with the most recent , even when a less recent claim has a higher rank? For instance, using on  returns the population as of, even though there are population figures for 2018 stored in the entity page. Is there a way to get the latest figures, without having to change all the ranks? Thank you for your excellent work, as always.--eh bien mon prince (talk) 21:29, 30 January 2019 (UTC)
 * , when you have the time, this issue is more current than ever after the deletion of several wrappers of Infobox settlement.--eh bien mon prince (talk) 03:27, 19 March 2019 (UTC)
 * Although I think the ranking system is most suitable for this and it is simply the data in Wikidata that is not up to date, I do see this can have added value. However, to make this as generic as possible I would like to add a sort function, but that's not trivial to implement. But I will see what I can do. Thayts   •••  11:40, 24 March 2019 (UTC)

Returning the top-level administrative division
I'm trying to use this template to fill the  fields of Infobox settlement, but I have trouble with it because of the way works up backwards from the lowest level division to the top.

So is the lowest level division,  is the second lowest, and so on. But is there a way to reliably retrieve the top-level division for the entity (or second-level, etc.), no matter how many divisions are below it?

For instance, the template would need to find the top level division on both  and, without changing the syntax. Can this be achieved? --eh bien mon prince (talk) 20:30, 16 January 2019 (UTC)
 * I don't think there is, unless there is a library feature for it that I don't know of. Note however that is not the top level division, because it itself is  of .  Thayts   •••  10:40, 18 January 2019 (UTC)
 * It would of course be possible to implement this with a dedicated command or so, but then when do you stop while working the way up? Also, an entity can have multiple properties, so which do you choose?  Thayts   •••  10:44, 18 January 2019 (UTC)
 * Thanks for the reply. This is some sort of 'solution' I adopted. Basically, called on a page like Lugano District, it checks whether the entity in is an , and if it's not, it moves up to the next administrative level. But it is extremely wasteful in terms of resources, and it cannot be scaled up to more than two or three administrative levels.


 * --eh bien mon prince (talk) 03:22, 19 January 2019 (UTC)
 * As I'd like to keep this module as generic as possible, I think this doesn't fit the module very well because is hard to implement in a generic way. What's still a possibility though is to create a template that uses this module and that is specifically designed for the task at hand. Thayts   •••  11:44, 24 March 2019 (UTC)

Template-protected edit request on 11 October 2019
As this module is now edit protected and I can't edit it myself anymore, please copy and implement the current contents of the sandbox to here. This is a small uncontroversial change as the code comparison shows, which replaces a hacky solution to get the global site ID with a call to a recently added dedicated function. I have added 4 testcases with a call to the  function, which is the only function that relies on the site ID. The testcases show the same results for the current version of the module and the sandbox version. Thayts  •••  08:58, 11 October 2019 (UTC)

In particular, while edit warring is always undesirable, it is particularly prohibited when using an advanced right. So, for example, if you edited this module using the TE right and someone reverted you (they would need the TE right to do that), there must be no further edits until the issue is sorted out on a talk page.

Wikidata Bridge
(Reposted from Module talk:WikidataIB § Wikidata Bridge.)

I'm guessing that the module maintainers might be unaware of this? The WMDE developers have been working on mw:Wikidata Bridge, which will allow some Wikidata statements to be edited directly through infoboxes and other templates. There's currently a semi-interactive prototype. I think it would be useful for the module maintainers to provide feedback, if there are any issues that haven't already been addressed.

There's an early draft of a documentation page that might help explain how the software's supposed to be enabled inside template code. Jc86035 (talk) 08:32, 3 July 2019 (UTC)


 * Thanks for telling. I was indeed unaware of this, but it is a great initiative that brings a lot of convenience! It would be easy to implement in this module too. Please keep us posted! By the way, will it also be possible to edit e.g. qualifier values? Thayts   •••  15:59, 18 July 2019 (UTC)
 * I don't think there is a definite answer yet.

 * I think I fixed the problem with this edit at Scholia. I don't know how the change to the module revealed that, however it seems ok. Johnuniq (talk) 09:21, 10 November 2019 (UTC)
 * (I've moved this discussion to a new section) That edit indeed introduced a generic check on the existence of an entity to mitigate error conditions with the   and   commands. I was not aware that it would introduce a new error condition, yet I found that this condition already existed for the claim commands and the edit made the module's behaviour therefore more consistent (but not completely). However, I think that an invalid ID should not result in an error, so I made another edit to check its validity and prevent the error condition. The template should have given valid input nonetheless, so thanks for fixing that.  Thayts   •••  20:56, 11 November 2019 (UTC)


 * The reported error comes from Wikibase because it is given an incorrect identifier. Same error as in . Jeblad (talk) 00:42, 12 November 2019 (UTC)

Failing verification
Somewhere in the code path for rendering reference there are probably one or more missing verification of existence of some substructure. In short a nil-value is passed where you are assuming a table, most likely because the table is empty in the statement, and it is thus removed. Always check whether the table exist, or fallback to an empty table. Also make sure that the code holds for empty tables, the code isn't totally consistent on empty structures. Or at least it wasn't.

I don't have any example, as all examples have been promptly fixed by changing statements. Jeblad (talk) 01:33, 6 November 2019 (UTC)

Use of underscore
Use of undersore as a variable name breaks several tools for Lua, as it is assumed to be used for unassigned values. Or breaks, some of them silently fails as statements involving an underscore are simply neglected. (Not sure if complete code paths involving a neglected statement are neglected.) Jeblad (talk) 01:24, 6 November 2019 (UTC)
 * The underscore is currently used in a very limited and controlled way, within a local scope. It's not used with Lua tools, so I don't think there is an issue really. Thayts   •••  21:25, 11 November 2019 (UTC)
 * Yes, but it is true that Lua convention is to use underscore to mean an unused variable. The code in the module is very clean and sophisticated but I was going to suggest that the global variables be cleaned up. I'll post a list and have a look at that later if wanted. Johnuniq (talk) 23:31, 11 November 2019 (UTC)
 * The statement “I don't think there is an issue really” does not hold when the issue breaks code verification. I would say “fix it”. Jeblad (talk) 00:52, 12 November 2019 (UTC)
 * That would be more convincing if there were an explanation about what breaking code verification refers to: what is the tool and how it is used? Johnuniq (talk) 02:47, 12 November 2019 (UTC)
 * Don't fix it if it isn't broken I would say, and it doesn't seem to be broken. However, if we're going to make a list of improvements anyway then I don't mind to put it on there. It's a good thing there are testcases now (although they cannot cover everything like defaulting to the current page's entity ID), so we should be more confident to make such changes.
 * By the way, the module is performing quite poorly (i.e. slow) so I will also be seeing what can be done about that. Thayts   •••  08:04, 12 November 2019 (UTC)


 * Any reference to a variable name consisting of a single underscore will lead to all errors involving this name being rejected. This happens with most of the tools for static analysis for Lua. If you don't want to fix it, fine, but then don't expect anyone to use time trying to track down errors within this module. Jeblad (talk) 00:56, 19 November 2019 (UTC)
 * Ok, I get what you mean: there might be errors that we don't know about because there might be tools running on this Wikipedia that suppress them. I'm also not necessarily against fixing it, so I just did that. Thanks for your input! Thayts   •••  21:58, 20 November 2019 (UTC)
 * Thanks, although I don't see why Jeblad is unwilling to identify the tool. Please check my recent edits to Module:Wd/sandbox. They are just style changes. Let me know if anything is a problem or unwanted. Once you have had a chance to examine the edits, I have some more minor points to discuss if wanted. Johnuniq (talk) 04:29, 21 November 2019 (UTC)
 * An example from Lua users: The variable consisting of only an underscore "_" is commonly used as a placeholder when you want to ignore the variable and more
 * "Note: This resembles the use of '_' in Haskell, Erlang, Ocaml, and Prolog languages, where '_' takes the special meaning of anonymous (ignored) variables in pattern matches. In Lua, '_' is only a convention with no inherent special meaning though. Semantic editors that normally flag unused variables may avoid doing so for variables named '_'(e.g. LuaInspect is such a case) [LuaLint and LuaCheck also comes to mind, but there are several others…]."
 * I guess it is fairly obvious why this naming scheme is a bad idea. Jeblad (talk) 13:28, 21 November 2019 (UTC)

Small change to make it easier to port to other sites
While updating the copy of this module at no:Modul:Wd, I came across a small issue. The test for whether a single value or multiple values should be returned, depends on whether the claim command ends with "s", but since the claim commands can be translated at the top of the module, this test generally fails for non-English languages. To make it easier to port the module to other sites, I would therefore suggest this slightly more verbose version of the test. – Danmichaelo (talk) 16:12, 13 April 2020 (UTC)

Maxvals & inverted
Hi, I have two question :

First question :

display :"",

how can I display just three first number for to have just : "17,181,084, 16,829,289, 16,779,575" ?

I have unsuccessfully tested "maxvals" and "numval" :

(display ever :"")

and

(display ever :"")

Second question :

display :"",

how can I to reverse the chronological order for to display : "17,132,854 17,000,000, 10,026,773, 16,779,575, 16,829,289, 17,181,084" ?

I have unsuccessfully tested "sorttype = inverted" :

Merge i18n and aliasesP
Hi! First of all let me say this module is awesome, super thanks to the developers! I just ported it to the Spanish Wikipedia and it's going great. The thing that surprised me the most, though, was the separation between Module:Wd/i18n and Module:Wd/aliasesP. It seems unnecessary to me and even counterproductive for easy and effective localization. So I'm thinking about merging them as my first contribution to this module (I'm an experienced developer and have some experience with modules too). However, before I do anything, I'd like to ask more experienced contributors if there's some reason for keeping them separated that maybe I'm not seeing. Thanks! Sophivorus (talk) 11:25, 15 April 2020 (UTC)
 * Thanks! The separation exists because they serve different purposes. Module:Wd/aliasesP used to be integrated in Module:Wd, but then I wanted to make use of the aliases list in Module:Wd/i18n too so I took it out of the main module. Module:Wd/aliasesP is not dependent on locale, so it doesn't really fit in an internationalization submodule. That's why I made it a separate submodule. Thayts   •••  22:47, 18 April 2020 (UTC)

Not most recent value if point-in-time is missing for one of the values


gave 2,3, i.e. two values. I want the most recent value, 3, which is from point-in-time 2019, and is the last in the list. I have tried the current, normal, normal+, best and single options but none of them helps. Probably because the older and first value in the list does not have a point-in-time (P585). My only solution is to apply, which gives. But that is an ugly solution - the most recently entered value is to my understanding typically but not always the last in the list, and should be the default if there is no timing info. However, your module gives the correct date if I enter

(I would prefer a y or yyyy option to only get the year. Now I have to apply to get the year.) I need value and date separated from each other, since the value is visualized graphically, and need to be sure that correct date is shown for correct value. [edited afterwards]

Tomastvivlaren (talk) 02:07, 23 November 2019 (UTC)


 * We're always dependent on the quality of the data in Wikidata for accuracy. We can make assumptions, but those are often also inaccurate. Assuming that the claim that was added last is the most up-to-date, for example, does not always hold if historic information was added later. Instead, Wikidata offers tools that allow us to select the most relevant information. In this case the rank tool can be used to mark 3 as the preferred claim. This module sorts claims based on this rank, from preferred to deprecated, so you will see that  [->  ] returns the preferred value.
 * The qualifier command gives the date value that you want since that is the only matching qualifier it could find. If claim 2 also had a qualifier of the same type, then that would also be returned. You could even use the (raw) qualifier value to select the claim that you want, but that is not a reliable solution since claim 2 could be assigned the qualifier in the future. Instead, the best way to go is to set the preferred rank in Wikidata which I just did.
 * Regarding the date, you could also do this:  [ ->  ]. If you want to get the value together with the year (and   [ ->  ], which also returns the month, is not good enough), then you could make two separate calls to construct value+qualifier. However, it's then depending on the rank and the presence of the qualifier if it is selected from the same claim as the value, so it would be best to keep it in a single call (like the   I just gave). And then an option to get only the year would indeed come in handy. I'll put it on my to-do list.  Thayts   •••  12:36, 23 November 2019 (UTC) [I added the current code response in your answer, within brackets]


 * Thankyou user:Thayts for prompt reply. However, then a bot should change the ranking to preferred value on thousands of Wikidata Items, or add point-in-time to the old values. If I restore the ranking for this item, the problem seems to return. You have not considered an option that allows the user to omit values without point-in-time - or to default prioritize those values that have a point-in-time? At Swedish Wikipedia, I just found out that the Swedish sv:module:Wikidata2 offers such an option, and solves my problem for now. At other wikipedias, where Wikidata2 is not installed, I really would like to use your module. (It is a petty that different Wikipedias cannot agree on a standardized set of modules, and that every Wikipedia has its own local culture regarding what module that people expect us to use.)

When importing into local wiki, error getGlobalSiteID nil value
Can anyone head me in the right direction to fix the error on this module when I import it into my own wiki?

The line in question has this code:

I have wikibase installed and seemingly working. In my LocalSettings.php I have the following definition for all of my local language wikis:

Where $wikiId resolves to the language identifier "en", "es", "it", "fr", "de", "pt", etc. My Wikibase is working and I can set interwiki language links just fine.

Why could the LUA script for this module be choking at this point?

I don't have any experience with LUA, I know PHP and Javascript, jQuery, some Java and C++, .NET... But I'm seeing there is a LUA console for debugging purposes when editing the module page. So I tried logging some values on my local wiki:

tells me that mw.wikibase is a table

tells me that in fact the function getGlobalSiteID doesn't exist:

Whereas if I log the same on the wikipedia module page, I see:

Doing a little more research, I see that the getGlobalSiteId function should be defined by the Wikibase client Lua module, see https://www.mediawiki.org/wiki/Extension:Wikibase_Client/Lua#mw.wikibase.getGlobalSiteId.

I wonder then why my Wikibase doesn't have this definition?

The "edit" (pen shaped) argument does not work properly
Hi, and thanks, I recently changed Google Chrome article at its Infobox part to fetch its "latest release" data by this template from its wikidata item. But it has a serious problem, when we click at the "pen shaped" link to edit its wikidata item, the link is redirected to the page https://www.wikidata.org/wiki/Q777?uselang=en#P348 and scrolls to "software version identifier" and at the top of it, and not scrolled to the correct position, that is at version "88.0.4324.39", for example. And this scenario also occurs for all of the "pen shaped" links in Google Chrome's Infobox, meaning that all of them are scrolled at the top of "software version identifier", and not scrolled correctly at the true "version" position.

Reference naming/duplication redux
I see in the archive that brought up reference naming for this template a while back. I've been encountering a similar issue, so I wanted to raise it again to see if we can figure something out.

Reference reuse is working fine when sourcing the same fact from Wikidata twice (say, in both the infobox and the lead), since we can just use  twice and they'll be merged. However, it isn't working when the same reference is used both from Wikidata to support one fact and in the article to support another. In this case, even if the display is exactly the same, the references remain separate. Moreover, it wouldn't be advisable to replace the article-based reference with the Wikidata-based one, since the Wikidata one could switch to a new reference that doesn't support the second fact. (Let me know if the above is confusing and I can provide an example.)

Would we be able to figure out any way so that the software can identify references that display the same and merge them, even if one comes from Wikidata and the other does not? &#123;{u&#124; Sdkb  }&#125;  talk 20:59, 10 February 2021 (UTC)


 * Hmm, experimenting a bit, this goes a little beyond just Wikidata.  display as two references, not one as they should, so the problem seems to be that the name difference alone throws off the software. I created a phab task. Even if we could have a working  , we wouldn't want to reuse   for instances where a difference fact is being supported, since the Wikidata reference could change. &#123;{u&#124;  Sdkb  }&#125;  talk 21:06, 10 February 2021 (UTC)
 * They display as two references because the name attribute is different. They only get merged if the name attribute is equal. I believe this is quite fundamental to the way references work in Mediawiki. If you want this module to use the same name attribute for any reference with the same contents that is defined in the article itself, then I guess the only thing that could be done is to get the article text (something that I've just figured out how to do as mentioned in the Dates don't respect MDY tag section) and scan for references. However, this is quite cumbersome and if the references are off by a few characters or show stuff in a different order, this is not going to work. On the other hand, if the references use the Citation template then we might be able to match on parameter values, but this still goes wrong quickly if a parameter has been set that this module doesn't recognise. Thayts   •••  23:11, 10 February 2021 (UTC)

As I suggested on Template talk:Cite Q, if the reference is described by a Wikidata item, for example: which uses, then the most appropriate name for this reference is Q25198336. Then if this reference is used again in the article, the same name can be used to group them together. &mdash; Martin (MSGJ · talk) 12:20, 11 February 2021 (UTC)
 * That would be possible indeed. However, Cite Q has more parameters than just the QID, for example "pages", "chapter" and "access-date". Module:Wd gives different names to such references that have the same QID but different parameters (because they are not completely the same). If you wouldn't do that, then only one would become prominent (and on some wikis even cause conflict errors) which might not be applicable to all instances. Also, this only works for references for which Cite Q can be used. Module:Wd also uses Cite web for references that contain a URL. Thayts   •••  18:27, 11 February 2021 (UTC)
 * , you seem to be talking about something different. Here's an example of what I'm trying to fix: at this revision of Scripps College, the academic staff count in the infobox has been converted to draw from Wikidata, with the code (slightly simplified), generating Academic staff:. However, the Common Data Set is also used to support Scripps' student body size in the body of the article, using the more typical code  , generating. These references are exactly the same, but they are not merged because the ref names are different (this is the bug I created a phab ticket for). We want to keep them separate in the code because, although they are using the same source, they are supporting different facts, and if the Wikidata reference is updated, it might switch to something that supports only the faculty count, not the student body size. However, we want them to be merged in the display for the reader because they are currently the same source. I'm pretty sure there's no way to do that until the phab ticket is resolved. &#123;{u&#124;  Sdkb  }&#125;  talk 20:02, 11 February 2021 (UTC)

Equivalent calls from within other modules
I was asked today how to call Module:Wd from other modules, so I made a brief demo at Module:Sandbox/RexxS/Wd and put some comparisons with the corresponding Wikidata calls on its talk page at Module talk:Sandbox/RexxS/Wd. I don't want to mess with your documentation, but I think those simple examples would prove useful to budding coders.

Get a person's date of birth from Wikidata
Good morning. Sorry if I write here, I don't know if it is the best place to ask the following question: How do I get from Wikidata the date of birth of a person expressed in day and month without the year (DD-MM)? Which template is the most suitable for obtaining this type of data? it's possible? Many thanks to anyone who would answer the courtesy and helpfulness. --Fierodelveneto (talk) 10:17, 23 April 2021 (UTC)
 * At enwiki, getting a date of birth from Wikidata is controversial although some templates do it. It's controversial because the result rarely has a reliable source and is easily broken by hard-to-find vandalism. However, if you can get a valid date, you can use #time (mw:Help:Extension:ParserFunctions) to change it to your desired format. For example,
 * In general, WP:VPT might be a better place for questions like this. Johnuniq (talk) 10:45, 23 April 2021 (UTC)

Titles from other wikipedias
, this is my first time looking at this, and I'm a bit overwhelmed. Is there a way I can extract the title of a linked Wikipedia article? For example: given Q43287 (German Empire) and a lang code 'fr', it should return the string 'Empire allemand', from the linked French article fr:Empire allemand. So, we'd have something like this:
 * → Imperio alemán

Is there anything like that present? I can't figure it out, from the doc. And with linked, then it would generate, etc. Thanks in advance. Mathglot (talk) 22:09, 18 April 2021 (UTC)


 * No, not as of now. The module has primarily been focused on supporting the local wiki only (i.e. returning values in the local language). But I might include an option in the next update! Thayts   •••  21:53, 22 April 2021 (UTC)

Making sure pieces of data belong to each other?
Hi, could someone explain more about this quote from the documentation? Combine multiple commands into one call to this template, instead of making multiple calls to this template with one command each, to be sure that all the returned pieces of information belong to each other. I assume this means that if I make multiple calls with one command each, then the pieces of information may belong to different statements. Is my understanding correct? If so, when and why does this happen, and can you give a working example? On another note, can multiple calls of the same module/template code result in different data being returned on different calls? Winston (talk) 05:23, 5 September 2021 (UTC)


 * Yes, your understanding is correct. For example, if you would like to take the of the  together with its  and you request those in separate calls, then you don't get the desired result:
 * → geoid (roughly)
 * If you are under the assumption that always the claim with the preferred rank is used, then you will be surprised to see "roughly" returned. This is because the preferred "geoid" property does not have a sourcing circumstances qualifier, but some with a normal rank do, so it simply selects these as they are the best ranked claims that do have a qualifier value of this type (I've added  just to return the qualifier of the first of two matching claims it finds). Instead, you should do this:
 * → geoid
 * You could use the  flag in the first example to restrict access to claims with that rank, but if there is more than one preferred claim then you end up in the same situation.
 * Also, I don't think multiple calls with the same parameters could result in different data, assuming that Wikidata always returns claims/statements in the same order (even for claims with the same rank). Thayts   •••  22:54, 15 September 2021 (UTC)

Controlling precision of dates
Often, when I'm fetching a date from Wikidata using this module, I'm only interested in the year, not the exact day, which would be too much precision for readers. I can accomplish that by wrapping the result in year, but that gets clunky (especially when there's references too).

Wrap label in nowiki?
At this testcases page, there is an example of a failure to render a retrieved label correctly, because the label has three ' (apostrophe) characters in a row. That string of three ' is rendered as bold markup instead of plain text. Please see this discussion for a similar problem with trusting raw wikidata values to be valid as wikitext output.

Can someone please wrap the label in nowiki formatting so that this problem does not happen? I suspect that there are subtle instances of this sort of error caused by this module on many article pages, not just this one testcases page. Here's a diff showing one way to handle the raw Wikidata text. – Jonesey95 (talk) 15:32, 17 February 2022 (UTC)
 * Pinging, for whom this might be a quick fix. – Jonesey95 (talk) 15:32, 17 February 2022 (UTC)
 * Okay, I fixed two things for that. First I did 1072641193 to fix the issue of escaping raw Wikidata labels when used in wikitext links but that did not fix the aforementioned test case because the testcase uses a Wikidata item that had no applicable sitelinks and the code avoided making a link for such cases (despite making links for properties which never have sitelinks). So then I did 1072645968 to make it so that Wikidata items will always yield links (when requested). They will continue to use applicable sitelinks when available but will fallback to linking to Wikidata in a fashion similar to how it handled properties (which never have sitelinks). —Uzume (talk) 19:22, 18 February 2022 (UTC)
 * Thanks for your attention. I never understand 100% of conversations when Wikidata is involved, but the testcases page that I linked above displays properly now. – Jonesey95 (talk) 19:31, 18 February 2022 (UTC)
 * Well, if you like, I can attempt to explain things at Wikidata in more detail. Let me know if you are interested. —Uzume (talk) 19:50, 18 February 2022 (UTC)

Linking non-notable people to Wikidata entry
I discovered here that when I use the "linked" flag, it produces this:. I want to use the flag so that NOAA will be linked, but when I do so, it also links to the Wikidata entry the author, who is not notable. This is not desirable, since only notable topics should be wikilinked. Could this behavior be disabled? &#123;{u&#124; Sdkb  }&#125;  talk 18:53, 20 February 2022 (UTC)
 * Another problem with  is that it adds access-date using the date of the most recent en.wiki article refresh.  Today, that is 20 February 2022.  Tomorrow it will be 21 February 2022 and etc.  That is wholly and completely wrong.  access-date is used to identify  date that a human editor confirmed that the cited source supported the text in an en.wiki article.  A fixed-in-time access-date allows editors to locate an appropriate archive snapshot if (when) the source goes 404.
 * —Trappist the monk (talk) 19:14, 20 February 2022 (UTC)

 * Ideally, we can keep the "nowiki" part of change but revert the "linking" part of the change. – Jonesey95 (talk) 21:15, 21 February 2022 (UTC)
 * Okay, I commented out that part (at Module:Wd), however, this will likely still be an issue as I only implemented the "nowiki" fix on the linked label path when an actual link is created (that us why I forced it to always create the link when requested by the link parameter, falling back to linking to Wikidata when there is no local sitelink) as that was the only time I was sure client code was not expecting the raw unescaped label value. Reverting this will break testcases for Wikidata items with no local sitelinks (but that have labels needing to be escaped when used in wikitext), e.g., Template:LinkedLabel/testcases. —Uzume (talk) 22:36, 21 February 2022 (UTC)
 * Okay, I think I fixed this. When a linked label is requested the label is always "nowiki" escaped even when there is no local sitelink and an actual wikitext link is not returned. Raw unescaped labels can still be obtained via this interface by not requesting a linked label (i.e., unlinked labels are not "nowiki" escaped). I still think this should always return a wikitext link when a linked label is requested; when there is no local sitelink it should link to the Wikidata entity as is done for properties (which never have sitelinks). —Uzume (talk) 21:08, 22 February 2022 (UTC)
 * Thanks again! – Jonesey95 (talk) 22:24, 22 February 2022 (UTC)
 * I have undone this part as it introduced link obscurity for no apparent reason. Also, I'm not in favour of linking to Wikidata if there is no sitelink just because of the example shown by . When you want to make changes like these, please discuss them on this page first. Thayts   •••  17:10, 23 February 2022 (UTC)
 * I see no issue there. Such things just came about while working on the issues presented here and a little cleanup while trying to understand and make such modifications. Properties have no sitelinks (local or otherwise) but they link to Wikidata. It seemed to me it made sense to return a link when a link is requested even when there was no local sitelink available. If that assumption was wrong, I have no issues discussing and fixing things. You will notice that such a change was introduced while I was attempting to fix the "nowiki" escaping for labels that contain valid wikitext markup. —Uzume (talk) 17:38, 23 February 2022 (UTC)
 * Properties are specific to Wikidata, so it's logical to link them to Wikidata. However, the purpose of linking (non-raw) entity labels was to link to their respective Wikipedia articles, if they exist. This because the idea was to make it possible to enrich Wikipedia with data from Wikidata by using this module. Nevertheless, perhaps a new flag can be added to allow linking to Wikidata in such cases. I also don't really understand how nowiki escaping is dependent on either linking or not.

Help for YouTube infobox
I'm in the process of converting the sandbox of Infobox YouTube personality to rely on Wikidata subscriber counts, which are now being updated every time they change by 10% or reach a new factor of 10 milestone. The WikiProject has expressed interest, too. I'm not sure how to get Wikidata to work correctly with it, though. I'd like to have it so that it returns but only when the qualifier  is present (doesn't matter what it's set to). Help? &#123;{u&#124; Sdkb  }&#125;  talk 07:40, 19 March 2022 (UTC)


 * @Sdkb: Currently, there is just one way to do it without showing the qualifier (as far as I know):
 * This requires the qualifier to be present, but puts it inside an HTML comment so that it's not rendered. Thayts   •••  10:54, 19 March 2022 (UTC)
 * @Thayts, thanks for that workaround! It's pretty clunky, though, and unfortunately it gets thrown off as soon as I try to use it with Format price, which doesn't seem to be able to handle hidden comments within the input. Would it be possible to modify Wikidata to provide a more direct solution? This would be one of the bigger uses of Wikidata on Wikipedia to date, and would be a huge plus for those whose watchlists are cluttered with subscriber count updates (or who are spending time doing the updates), but we'll have to overcome this obstacle in some way to get it to work. It seems rather silly that Wikidata decided to lump together Twitter followers/YouTube subscribers/etc. in the same property, but given that, we definitely don't want Twitter followers to accidentally show up as YouTube subscribers. The edits so far to the sandbox are here. &#123;{u&#124; Sdkb  }&#125;  talk 19:04, 19 March 2022 (UTC)

 * This is the first time you've mentioned needing the subscriber date! And I'm not clear why you're using {format price} because it isn't a price? It might help if you could be clearer on exactly what output you are seeking. It seems a rather strange way to structure the data on Wikidata. A more traditional structure might be something like this:
 * → →  →  → 574000
 * If this structure is becoming common we should perhaps look at supporting it with this module. PS, I've just seen your post on WD and completely agree! &mdash; Martin (MSGJ · talk) 09:35, 23 March 2022 (UTC)
 * Indeed, if the only reason to use format price is to add delimiters, then you can simply use wd without the  flag as shown above. If you mean you also need  as the subscriber date, then you can use the same approach as I showed last time and you could even use the raw followers value to pinpoint the right claim like so:
 * By the way, I am still working on a version that allows you to select claims that have some value for a particular qualifier. Thayts   •••  08:28, 24 March 2022 (UTC)

Use of reference parameter should provide archive URL where available to deal with link rot
On Telugu wikipedia, we have started using Wikidata based infobox templates extensively.(Example page on Tewiki) When the citations are added, we are facing the problem of dead links when values of full work available at URL become dead as given below.

Arjunaraoc (talk) 04:03, 1 June 2022 (UTC)

Reference is shown differently on Tewiki when only 'stated in' is present
This code below does not show citation differently (only label is shown and the link, wikidata identifier for source is missing) on Telugu Wiki (Example test page) On English wiki, there is no problem. Telugu Wiki uses English wiki templates and Module code as much as possible, without even change of parameter names.

 * @Thayts and others, I have checked the availability of latest files of enwiki on tewiki.  The testcases 1 and 2  are failing. (See te:Module Talk:Wd/testcases/1 as an example.)

Arjunaraoc (talk) 09:21, 2 June 2022 (UTC)
 * The reference looks different because there is no Cite Q template available on that wiki. Testcases 1 and 2 are failing, because there is no Utrecht (province) article on the wiki either; you can better replace the Q-number with one that does have an article. And the issue with testcase 4 seems to be in te:మూస:Cite web, which appears to be a one-to-one copy from the English wiki that does not recognise the month name in your language. You should update all localised terms there. Thayts   •••  08:55, 5 June 2022 (UTC)
 * @Thayts, Thanks. I already copied Cite Q template to Tewiki, but did not update sitelinks on Wikidata. After updating Wikidata, the citation is same as on Enwiki, except for the non-localised date. Cite Web, which I think uses Module:Citation/CS1/Configuration has already been internationalised to used Mediawiki local language configuration as per discussion.   Citation showing  English dates is not  a major issue on Tewiki. Arjunaraoc (talk) 05:21, 6 June 2022 (UTC)
 * @Thayts, I made changes to test cases to use Q668(India) in place of Q55(Netherlands) and Q1159(Andhra Pradesh) in place of Q776 Utrecht (province). Still I got few Lua errors on some lines, which I commented for the timebeing. I found that though the actual, expected are same, the test is being shown as failed (example:  on te:మాడ్యూల్_చర్చ:Wd/testcases/1  _), which you may like to investigate and fix.

 * @Thayts, I tried to clean up the references for some entities, with the order of values against a property changed, I find that the references are not shown at all.

 * For now, you can change the rank of the claim for 2021 to "preferred" on Wikidata and then use .  Thayts   •••  20:22, 5 July 2022 (UTC)
 * Thank you! This is fine for just this one suburb, but its not really tenable for all the areas in Australia with population data from the 2016 and now 2021 census. A better solution is probably needed. Why can't current also consider the point in time property to work out the most CURRENT claim? It seems odd for this template to ignore the claim's point in time when getting the CURRENT value. Betterkeks (talk) 07:44, 6 July 2022 (UTC)
 * The "current" flag takes a period into account and checks the start and end time to see if the period is, well, current. A point in time is quickly outdated and 2021 is indeed no longer current. However, a "latest" flag would help here. Thayts   •••  09:09, 9 July 2022 (UTC)
 * A "latest" flag would work, but so would a polymorphic "current" that is also simpler. The 2021 census data are still being released and the population data were JUST released a short time ago. These data ARE the MOST current data available until the next census data are released in probably five years time. The wikidata template yielding data from 2016 as "current" DESPITE being able to yield MORE "current" data from 2021 does not seem right. Betterkeks (talk) 11:04, 9 July 2022 (UTC)
 * "Current" means "as of this very moment in time", which is inapplicable to census data, since it's always released months after the period over which it is collected. By the time it is released, it's no longer "current". It can be "latest" or "most recent", but it can't be "current". (Compare with the well-defined "current number of people on the ISS".) — UnladenSwallow (talk) 17:07, 22 July 2022 (UTC)


 * My dictionary defines "current" as meaning (1) passing in time, or belonging to the time actually passing: the current month, (2) publicly reported or known, (3) prevalent, and (4) generally accepted; in vogue. (It also defines current in terms of “flow”, but that isn’t applicable and so for brevity I haven’t listed these here.) The current census data is (2)-(4), and (1)-(4) when considered the currently best known data. However, even if CURRENT for this template is assumed to mean "as of this very moment in time" only (which is a much narrower definition than my dictionary provides), then it should ONLY yield the 2016 data on, or when given the date for, census date 2016, and NO data at all otherwise, rather than picking the first entered data that it yields currently.

 * It seems to me wrong for you to include  tags in format. To me, that belongs outside of the  .  But, since you did include  tags, why did you omit the <li ></li> tags?
 * For open date ranges like that of your example, a simple tweak to the string replace works (<ul ></ul> tags removed):
 * Because it is to be expected that not all dates will be open ended, you could write something like this (here the return from  is a mockup):
 * result when returned string has two dates:
 * result when returned string has one date:
 * The above assumes that there will be at least one dd Mmmm YYYY date.
 * According to MOS:RANGES, the correct separator for a range of two whole dates (dates that contain spaces) is spaced endash: 30 April 2013 – 30 April 2015. The above does not support that because your format always uses an unspaced endash.

Using this to access the latest release date
Could somebody who understands this template (and accessing Wikidata generally) have a look at WP:Teahouse? The problem is that the call of this template in the infobox in diagrams.net was picking up the release dates of all the versions in d:Q59339175, rather than the latest. I tried to fix it by adding  - which got rid of all the dates, but actually doesn't produce any because none of them have been marked as "preferred". I was investigating how d:Help:Ranking worked, and was going to set the latest release to be "preferred", but it occurred to me that this must have arisen before, and there must be a better way to handle it. I wasn't sure whether to ask at Wikidata, or VPT, or here, but I thought I'd try here first. Pinging, who raised the issue. ColinFine (talk) 17:34, 2 September 2022 (UTC)


 * To re-mention what @ColinFine said above, we want the Diagrams.net article to use the latest software release version number that has been entered in its associated Wikidata page.
 * I tried to copy-paste the Wikidata property usage from the infobox template on an existing page that already pulls its data from Wikidata, like Adobe Photoshop, but it appears that there must be more that needs to be copy-pasted (or changed) than just what’s in the infobox template, because doing so didn’t work. I’m not sure if there is additional Wikidata syntax on (as an example) the Adobe Photoshop page that I missed, or if there is some additional syntax that needs to be entered separately on the affiliated Wikidata page.

Broken row in documentation
In the table at Template:Wikidata/doc, the last row appears to be displaying incorrectly. I think the " " is meant to go right under "edit" but it's instead appearing one cell to the left.

Add a 'maxvals' option as in Module:WikidataIB
Hi, We are currently trying to import referenced data from WD into infoboxes but we have the issue that for some items, lists could get too long. So having a 'maxvals' parameters as in https://en.wikipedia.org/wiki/Module:WikidataIB would be really nice! (as WikidataIB does not allow to retrieve references) Has anyone seen this? Could this be doable? AdrianoRutz (talk) 08:42, 7 October 2022 (UTC)

Possibility to get historic labels
Hello, is there any way to fetch older labels of a subject? For instance, I would like to get Kirovabad (linked) for Ganja via P1448 using a date interval (1935–1989). That would be helpful for getting the correct labels during a person's lifetime. <span style="font-family: 'Droid Sans', Calibri, Verdana, sans; color: silver;">— Toghrul R (t) 07:02, 1 November 2022 (UTC)


 * I don't know of any way to do that currently, but I can see it could be useful. Complications: there could be several values which are valid in a certain date, would need to filter results by language. I can't see any way it could be linked because these are text labels and so not linked to any articles. &mdash; Martin (MSGJ · talk) 08:12, 1 November 2022 (UTC)

Area
I have been using the template to create lists of suburbs in LGA articles (see Shire of Serpentine-Jarrahdale as an example). It was pointed out to me that the statement drawn from Wikidata, "3.5 square kilometre", is actually incorrect and it should be the plural "square kilometres". The way around this is just to use the "raw" parameter and add square kilometres at the end of the template. Apart from this, it would also be handy to be able to convert the value to the US square mile. I achived this with the convert template, resulting in the rather complicated undefined km2. Is there currently any either way with the template to achieve the following two:
 * Substitute the Wikidata unit with an abbreviated unit (like km2)
 * Convert the unit from SI to Imperial and vice-versa

Thanks for any advice. Calistemon (talk) 04:40, 28 November 2022 (UTC)
 * When I look at the Wikidata entry for Byford, I see "19.6 square kilometre" under "area" and "64 metre" under "elevation above sea level", which appear to be wrong. That is not a valid way to write distance or area in SI. The table at MOS:UNITNAMES even makes this explicit for those who need to hear it: "SI unit names are pluralized by adding the appropriate -s or -es suffix". I think that strange way of writing units is where the problem lies, so fixing it at Wikidata is probably best. – Jonesey95 (talk) 06:29, 28 November 2022 (UTC)
 * @Calistemon: please use  which produces undefined undefined &mdash; Martin (MSGJ · talk) 07:24, 28 November 2022 (UTC)


 * Or just  to produce undefined undefined. Betterkeks (talk) 09:00, 28 November 2022 (UTC)

Access value by date using P585 point-in-time
Why isn't it possible to access specific values by comparing date against P585 point in time not just start and end time? Say call for a value that has point-in-time value in January 1st 2022 because not all values can be correctly described as having start and end points, some for example population is specifically point-in-time value as it is changing day by day. Is it not implemented because it is not possible or it hasn't yet been deemed useful? If it's possible how could it be done? Does someone else add the functionality or do I copy the code and try to add the functionality and then if it is successful it may be added to main Module? Liinisx (talk) 11:48, 5 January 2023 (UTC)

Template-protected edit request on 5 January 2023
Add functionality to call for a property value if "date=..." matches P585 date-in-time value As I understand it is not possible for now and one can call for a value by date only if it has start-time and/or end-time qualifiers Liinisx (talk) 14:21, 5 January 2023 (UTC)
 * Unless you can code this yourself in the sandbox and test it, this probably will not get done. This module is no longer actively maintained, and the last time I tried to edit the code I made little progress.

Examples in the main page
The examples in the main page are kind of difficult:

↓ 17,282,163 (2019), 16,829,289 (26 August 2014), 16,779,575 (2013), 10,026,773 (1950), 17,000,000 (21 March 2016), 17,132,854 (2017), 17,181,084 (1 January 2018), 17,622,200

The results aren't in any order - neither by time, nor by size.

What I want is eg Santa Fe, Cebu using P150 which can have a number of elements in alphabetic order. They are each similar eg Q26763388, and from each I want (P1082) the most recent population, and the closest earlier. If I can work it out, that can do the whole job is one line (adding text where needed). - Auntie Kathleen (talk) 06:05, 6 January 2023 (UTC)


 * I guess it is giving the values in the order that they are on Wikidata. I have changed the order on there (using wikidata:Help:Statements and now it displays 2019 first (which is the statement marked as preferred) and then all the others in chronological order, and then the undated one.

Is there a risk for overusing this module?
Hello. Thank you for developing this amazing module. I am working in the Ladin language Wikipedia, where I have created this module by copying this code and it works well. I have started using this module a lot on many articles, because the Ladin Wikipedia is very small and there aren't enough people to regularly update information, so I try to automatise everything as much as possible. I have found that when an article contains several instances of "module:wd", like five or more, it can take a while for the page to display the information. I include this module both in infoboxes as well as in the text of the article. When it takes longer to display the information from Wikidata, it may even show only certain information from Wikidata but not other. I don't think it's a syntax issue, because other pages with the same syntax did not have this issue.

Therefore, I wonder whether there is a recommended guideline against overusing this module, whether using it five times on every single page in the entire Wikipedia would slow everything down considerably. Or is this practice fine? Do the long loading times only happen when the Wikidata item or the Wikipedia article are edited, and otherwise it just loads the information once and then it's fine?

Thanks for helping. Asenoner (talk) 13:01, 19 March 2023 (UTC)

Edit request 4 April 2023
Description of suggested change: I would like to update this module with my revision of its sandbox (permalink). I've made the module slightly simpler by simplifying its conditional statements, and fixed two minor errors in pattern matching (attempts to escape w/ backslash instead of %). I've checked my changes in /testcases, and my version appears to fare equally to the current revision.

Reference formatting bug when using "author name string" (P2093)
When a reference on Wikidata includes the "author name string" qualifier, the resulting citation is formatted improperly. It should be formatted the same way as when the "author" (P50) qualifier is used. See the reference 1 on GNU GRUB for example. This issue was already discussed in 2020, but it seems that it wasn't solved. Janhrach (talk) 09:58, 6 January 2023 (UTC)

 * Thanks for looking into this. Have you got any test cases where we can check that everything is working properly? &mdash; Martin (MSGJ · talk) 17:21, 2 March 2023 (UTC)
 * I don't have any new testcases. I'm not sure how do the testcases of this module work, but Module:wd/testcases/1 references only the original module and testcases 2 and 3 also reference the sandbox. I've made a tweaked copy of testcases/1 at Module:wd/sandbox/testcases/1 and its output seems to be the same as before my edits (5 errors reported). The output of the testcase 2 and 3 is also the same as before. However, I've made a very basic test page for my changes at User:Janhrach/sandbox. Janhrach (talk) 06:11, 3 March 2023 (UTC)
 * User:Janhrach/sandbox proves the point that I made below; the template called from wd/sandbox is using authors so that thing in your sandbox will, if used in mainspace add the article to .  So, I oppose the proposed change.
 * —Trappist the monk (talk) 15:48, 3 March 2023 (UTC)
 * If I understand what it is that this change accomplishes, I think I'm opposed. At line 69 of Module:Wd/sandbox/i18n is this:
 * If I understand the purpose of that, it is supposed to assign whatever value wikidata has for P2093 to the parameter authors.  Use of that parameter is discouraged and it will (someday) go away.   assigns P2093 values to author as a fallback (if one is to believe the module documentation at line 245).  Neither of these solutions is a good solution when P2093 lists more than one name.  Because P50 can (and does) hold more than one name it seems to me that wikidata q values using P2093 should be fixed to use P50 and this module tweaked to support that.  Assigning P2093 to authors seems to me a hack that will come round to bite someone later.  Don't do that.
 * —Trappist the monk (talk) 18:19, 2 March 2023 (UTC)
 * I have just noticed that P2093 is supposed to hold one author at once, and if there are more authors, the reference will have more P2093s. For example, see the items listed at the "Most recently created items" URL at d:Property talk:P2093. I suggest to use  (instead of  ) for holding P2093s. Janhrach (talk) 14:55, 3 March 2023 (UTC)

Please copy the contents of the revision 1142767581 of Module:wd/sandbox/i18n into Module:wd/i18n and the contents of the revision 1142771233 of Module:wd/sandbox into Module:wd.

I've implemented the handling of P50 and P2093. In my implementation, each P50 and P2093 has its  parameter, with (template) parameters for P50 having lower   than parameters for P2093. For compatibility reasons, I have retained code that would handle multiple properties other than P50 and P2093. I've also tweaked the fallback display of citations (used when a citation has parameters not supported by Cite web or when it doesn't include title or URL). The authors from P2093 are now displayed properly and the author separator was changed from " & " to "; ". The parts of the citation are now separated by ". ", not by "; ". For output examples, see User:Janhrach/sandbox. Janhrach (talk) 09:18, 4 March 2023 (UTC)

Edit: see the comment from March 11.
 * This cite seems to be more-or-less correct; this cite does not. It appears that for some reason you are inventing your own citation style which would be ok if it were the only style to be used in articles that use this module.  Alas, editors like citation consistency.  I'm guessing that the reason for this different style is to prevent the embedded  template from emitting an error when wikidata does not have a title for the citation.  Titles are required so when  emits a missing title error, that is a good thing, because someone can go to wikidata and fix it (P1476).  I'm inclined to oppose because of the non-standard citation style.
 * —Trappist the monk (talk) 15:02, 4 March 2023 (UTC)
 * I did "invent" a new citation style (which is a slight modification of the previous one), but I did not come up with the idea of a fallback mode. See the updated version of my sandbox for the original behavior of the module. So, is your opinion to remove the fallback mode and issue an error instead, or is it to keep the fallback mode and to issue an error only if the title is missing? Janhrach (talk) 16:21, 4 March 2023 (UTC)
 * I would get rid of the fallback format as it exists now. If that is not possible, at the very least, the fallback format should look (to the reader) just like a cs1|2 template rendering.  Maybe fallback format can use  with cs1:
 * This looks much the same as the and  template renderings; sort of.  In the event that there is no url but there is a title,  will treat the citation as a book cite:
 * One thing that should be done with this referencing stuff is to set Wikidata Q&lt;number> so that editors know where to go to fix missing/broken url/title/whatever. yeah, there is a pencil icon... forgot about that.
 * I should say that while I have contributed to Module:Cite Q, I am, in general, opposed to its use and, by extension, to this module because both create buggy, hard to fix citations.

Deactivating edit request as still pending discussion and not ready to be implemented. * Pppery * <sub style="color:#800000">it has begun... 22:15, 4 March 2023 (UTC)
 * I've changed my opinion, I disagree with using Citation as the fallback mode. In my opinion, there are two good options – the fallback mode would retained, but it would issue a warning; or the fallback mode would be removed and an error would be issued if the module is unable to produce a valid template. I think the fallback mode (if retained) should be only temporary, and in the case a citation triggering the fallback mode appears, the citation (or, in special cases, this module) should be modified to produce a valid template. Janhrach (talk) 08:51, 5 March 2023 (UTC)

I'm reopening this edit request. The discussion above is not directly related to my proposed fix. I made minor changes to the fallback display of citations, which (the changes) are partly unrelated to the rest of the fix. If you dislike them, please replace the main module file with the sandbox revision 1142765292 (instead of 1142771233). The below above discussion is about completely changing the fallback display of citations (as the resulting citations are not formatted consistently with CS1/2), which is neither something I wanted to address in my fix, nor something I am experiened enough to do. Addressing the inconsistency of fallback mode-generated citations can (and, in my opinion, should) be done later by more experienced editors than me. Janhrach (talk) 14:43, 11 March 2023 (UTC)

 * —Trappist the monk (talk) 15:32, 26 March 2023 (UTC)
 * I have removed the fallback mode, see my sandbox for the output. One problem is that Wikidata doesn't seem to mandate any other reference parameters than URL. See the first error in Module:Wd/sandbox/testcases/1. The  command breaks, because one of the references triggers the (now inexistent) fallback mode, which can be considered a problem.

 * Emitting a Lua script error is clearly the wrong thing to do because it misleads the reader into thinking that the problem is in the Lua module when it is really in the wikidata:
 * Lua error in Module:Wd/sandbox at line 250: A reference contains malformed parameters.
 * Why would you have the module emit an error message like that? Error message must be meaningful or at the very least link to documentation that explains the error message.  Further, using <strong ></strong> and a larger font size for error messages is a lot like SHOUTING; don't do that.

In technical sense, the term "[incompatible] combination of parameters" includes the fact that the citation lacks the needed parameters. Since it will be probably unclear what it means, it can be replaced with something like: "Error: Unable to display the reference properly. See the documentation for details." The documentation would include something like this (under the subtitle of the error): "The Wikidata reference doesn't contain the minimal set of parameters (title and reference URL for Cite web, "stated in" for Cite Q) or has a set of parameters incompatible with both Cite web and Cite Q". As for the error that disappeared, the reason for its disappearance is that the new error message is returned from the getReference function to avoid terminating the whole script, as calling error did. The "sourced" command counts error-returning references as valid, and I don't think it's a problem – there is no policy that only statements with references renderable with Cite web/Cite Q are considered sourced. Janhrach (talk) 14:19, 30 March 2023 (UTC)
 * Most editors at en.wikipedia are not technical. Error messages or the explanatory text  from the error message must be written so that any editor can learn what is wrong and how to fix it.  'Technical' answers have no place in error messaging unless the 'fix' is only intended to be fixed by technical editors.
 * As an example of poor documentation, look at . That section is the only place where  is mentioned.  As it turns out, the mention is incorrect; the citation is rendered by, not by .  I went looking because stated in is not a  parameter just as reference url is not a  parameter.
 * Just because I was curious, I switched the example template at to use the ~/sandbox:
 * Really? Should that error message be there?  The  rendering produced by the live version of  is exactly the same as the reference produced by ~/sandbox – neither are 'good' citations but that is one of the huge failings of.

 * The example from the Cite Q documentation is wrong because new claims (about the area of Regensburg) have been added since the example was written. Now (as opposed to the time the example was written), there are 2 references supporting the newest claim (as opposed to the one that was intended to appear in the example), but they aren't enclosed in ref tags because of the raw command, so on the first look, they look like one citation. None of the references uses stated in, so they can't be rendered using Cite Q. If you don't understand me, just look at . On the "80.85 square kilometers" claim (which is inadvertently used on the documentation page), the first reference lacks a title, so it causes the error. The second reference is just a normal URL reference. The "80.81 square kilometers" claim is probably the one intended to appear in the example in the Cite Q documentation.
 * As for the inexistent  parameter, it isn't used because the   Wikidata property is mapped to the   parameter of Cite web in Module:wd/i18n. The   property is mapped to the first (unnamed) parameter of Cite Q.
 * As for the new error message suggested in my last comment, is something wrong with it? Is it still too technical? Janhrach (talk) 14:49, 31 March 2023 (UTC)
 * I wasn't trying to get you to justify or explain the poor documentation at . I used it as an example of what  to do.  Apparently I failed to communicate – a personal failing that has oft been commented on at en.wikipedia.
 * Error: Unable to display the reference properly. See the documentation for details. What 'documentation' where?   to it.
 * The Wikidata reference doesn't contain the minimal set of parameters (title and reference URL for Cite web, "stated in" for Cite Q) or has a set of parameters incompatible with both Cite web and Cite Q" A point I was trying to get across is that  does not have a parameter called reference URL and  does not have a parameter called stated in.  I don't know that it is necessary to distinguish between  and .  Perhaps you should avoid the word 'parameters' because wikidata doesn't have parameters.  The  help text should explain what properties are required and how to decide whether to use  or to use  and.
 * The help text should also describe how to find the reference that needs fixing.  The  documentation is an example worth noting.  Wikidata change at the whim of wikidata editors who aren't necessarily wikipedia editors so error messages will pop up unexpectedly on en.wiki articles.  Editors at en.wiki won't know why the error messages have suddenly appeared and don't know how and where to fix them.  It is important that non-technical and/or novice en.wiki editors be told where to find the source of the error and be given instruction on how to fix that error.

I have clarified the sentence you have mentioned. In the sentence I originally assumed it is clear that the module attempts to use Cite Q only after using Cite web has failed, but now I agree with you that the original sentence needed to be clarified. As for the tables, I don't think it's a good idea to merge them, because they describe different citation renderings which shouldn't be confused. Janhrach (talk) 17:03, 14 April 2023 (UTC)

Support for rounding
One of the most common things I do with information I draw from Wikidata using this template is rounding, since it sounds terrible to say "the museum has approximately 14,747 items" rather than "the museum has approximately 15,000 items," which is easier to read and doesn't imply a false precision. However, the current functionality of the module requires me to fetch the raw value, round it, and then fetch the unit/references separately, which is very clunky. Would it be possible to build in functionality for rounding so that this can be simplified and used more widely? &#123;{u&#124; Sdkb  }&#125;  talk 21:25, 9 May 2023 (UTC)

Non-ASCII numeric delimiter
This is probably not so important for enwiki, but people are copying the module to other wikis and might find it useful. When the  in Module:Wd/i18n is set to a non-7bit-ASCII value (for example, to , narrow no-break space) the   method reverses UTF character bytes in

A quick solution is to first use some symmetric ascii-7 improbable character combination, such as :

References mapping
I cannot find the discussion, but I know I've talked a bit previously about how it can be difficult to map the properties used for references on Wikidata to the CS1 parameter fields here on Wikipedia, particularly when it comes to the website/work fields.

The current mapping uses for website. That's generally good, although I often see "stated in" (mis-?)used on Wikidata for things that we'd consider here to be a publisher because they're not italicized (whereas websites/works are italicized). However, there are also other related Wikidata properties.

is sometimes used when the work/website doesn't have its own item. I think that it should probably map to.

is also sometimes used. The distinction between it and "stated in" doesn't appear to be as well-defined as it could be.

I'd appreciate some high-level discussion about how we could improve this mapping. &#123;{u&#124; Sdkb  }&#125;  talk 20:49, 7 June 2023 (UTC)

 * I gotta say, I rarely use the work / website parameters with any kind of precision. Lots of times the citation is to a source that's published in print but accessed via the internet. I do a lot of cleanup of script-assisted refercing, and if the script does something dumb like keep the name of the website after a pipe or ndash in the title= parameter while filling out the website= parameter with the first bit of the URL, I'll just reparameterise the human-readable name of the website to publisher, since it displays the same to the reader. Also since you can't double up on website and work, I've put the name of the periodical (or whatever) in the work parameter, and the website in via=. I hope nothing critical is depending on using these parameters precisely, and if so I'd recommend as a first step that Citoid change its output from website= to via=. Folly Mox (talk) 23:35, 7 June 2023 (UTC)
 * The cs1|2 templates produce COinS metadata for those readers who consume citations with reference management software (Zotero is one such tool – which, by the way, is a significant contributor to Citoid... we cannot complain about the quality of the data that it produces without we first put our own house in order). publisher is not defined for, so not included in, the metadata for  or for any of the periodical templates .  work is a generic alias of journal, magazine, newspaper, periodical, and website.  Omitting these parameters from their associated templates prevents that important bit of bibliographic data from getting to Zotero and other reference management software.  Similarly, work and its aliases are not defined for, so not included in, the metadata for book, encyclopedia, conference, etc templates.
 * via is a visual-only parameter not defined for the metadata for any of the cs1|2 templates. It would be very wrong of Citoid to use that instead of the appropriate work parameter.  Further, via has a specific purpose: to minimize astonishment when the reader lands at an on-line location that is different from the publisher's on-line location; see the (not really very good) documentation.
 * It is good to [parameterise] the human-readable name of the website but it should not be to publisher. website should only get the domain name when the source is best known by that name.  See also: .  We are citing the publisher's work, not the company.

 * I am trying to create the best citations possible – in general: sometimes I get lazy and perform the reparameterisations described above – and I don't want to come off as oppositional, since I recognise we're on the same team. But if website= should only get the domain name when the source is best known by that name, why do scripts assign that parameter the domain name more than nineteen times in twenty? Can things be adjusted such that the website= parameter gets assigned the domain name for a whitelist of domains, a human-readable name when the appropriate function can determine one, and remains unassigned in all other cases?

Problem in Template:Infobox Russian inhabited locality
I recently edited Kazan as part of a citation repair project, and one of its references displays the pink text Error: Unable to display the reference properly. See the documentation for details., with "the documentation" linking this module.The error is coming from Template:Infobox Russian inhabited locality, in the bit about 2018 population estimates, where it calls.

gsub pattern bug?
I was editing the module on another wiki and the editor warned me of an invalid escape sequence in

If I'm reading the manual correctly, the escape character is indeed %, not \. So  should be replaced with   (twice). Ponor (talk) 21:44, 25 May 2023 (UTC)
 * You are probably correct but try these in the debug console:
 * → something 1
 * → something 1
 * → something 1
 * Number three is probably the 'most' correct. I expect that number 2 works because is doesn't make sense to quantify the zero-width assertion  .  Does number 1 work because of a flaw? because   is a character-in-a-string-escape-character (similar to:  )?  I don't actually know.
 * —Trappist the monk (talk) 22:25, 25 May 2023 (UTC)
 * I'm only guessing (and mostly repeating your ideas), but it could be that whatever parses that pattern-string first reduces #1 to #2 (there's a mention of something similar with \ddd), which then works because + means nothing but + after that ^.

 * I thought that that might be the case, "Category:Module:Wd reference errors" would be fine.

I've fixed the handling of database references. The sample output in my sandbox. Previously, database references were displayed using Cite Q with an additional id parameter, see for example the reference no. 8 in my sandbox. Now, the module fetches properties from the item in. Then a URL is generated from the first P1687 whose datatype is external-id and is present in the reference; the generated URL is then handled in the same manner as. Additionally, I have modified the handling of to use it as title only when a URL is present to avoid bugs. I would be happy if you reviewed my code. Janhrach (talk) 16:28, 3 July 2023 (UTC)
 * After a bit of work with Ponor I've just put through a set of titles for refs on Philippine town items, which should clear about 1500 pages out of this category when it's finished processing (hopefully later tonight). Sampling some of the others I think the majority are likely to be also missing a "title" field. However, there are a few complicated ones - eg I have no idea what is going on with Canadian English, where the references seem to have the right metadata. Andrew Gray (talk) 22:38, 27 June 2023 (UTC)
 * Just to be clear, it was my unsuccessful attempt, and Andrew was kind enough to sort things out properly. I'm only thinking: wouldn't it be better to have a link in those red messages that takes you straight to wikidata, where a title is missing, instead of the generic message that leaves you clueless where and what needs to be done?

 * Thanks! Cleared off another 200-odd now. I think that might be the easiest ones but I'll see if there's others that can be solved in a batch - there seems to be some possibilities with Swiss data there but I haven't quite disentangled it yet.
 * Looking at Canadian English which I mentioned above, I think the problem here is that the reference statements have . This isn't supported by the mapping for either cite web or Cite Q, which I think is why it's going to an error message.
 * This particular case is a weird one, but in general this is a fairly common pattern for things which are sourced with an ID property - combine "named as" with and an ID property - example. I wonder then if it would be worth tweaking Cite Q so that it can treat  as a backup to  if an actual title is not present (the ID properties are already supported by Cite Q). That might clean up a swathe of them. Andrew Gray (talk) 23:26, 28 June 2023 (UTC)
 * Don't quote me on this, but I believe this is all using Cite Web not Cite Q. -- LCU ActivelyDisinterested ∆transmissions∆ °co-ords° 00:29, 29 June 2023 (UTC)
 * Yes, you are right. And is right that the problem is with . I think it is a good idea to modify this module to use P1810 as title when  is not present. By the way, I thank Andrew Gray very much for his work on eliminating the errors. Janhrach (talk) 13:32, 30 June 2023 (UTC)
 * I've implemented the suggested changes in the sandbox. A sample output is in my sandbox. The first test shows that the module correctly removes . The second and the third reference in the second test shows that the module uses P1810 as the title if is missing. However, the output isn't correct – the replaced title is actually the name of the database. But this is just a consequence of the incorrect handling of database references. Until I will have completely fixed the handling of database references, I am not going to make an edit request fixing P1810. Janhrach (talk) 15:34, 1 July 2023 (UTC)


 * @Janhrach the output there looks good, thankyou for looking into it! Andrew Gray (talk) 21:20, 4 July 2023 (UTC)
 * I was hoping this would help clear down the cat, big it's doesn't seem to have happened. Wasy expectation wrong or is there some other update that has to happen? -- LCU ActivelyDisinterested ∆transmissions∆ °co-ords° 12:14, 11 July 2023 (UTC)
 * I think most of the errors are caused by missing titles in URL-only references or similar. That couldn't be fixed any other way than by improving Wikidata. Janhrach (talk) 12:37, 11 July 2023 (UTC)
 * Thanks for the explanation. -- LCU ActivelyDisinterested ∆transmissions∆ °co-ords° 12:39, 11 July 2023 (UTC)
 * @ActivelyDisinterested I think someone may have enabled a new infobox lookup or similar as well - it was down to about 1000 at one point and has now risen again. So I guess that new additions are outpacing any corrections. Wonder if it's possible to track those numbers somehow, hmm.
 * I'll see if I can figure out some more potential batch fixes on the WD side to try and bring it down again. Andrew Gray (talk) 16:59, 11 July 2023 (UTC)
 * PetScan allows you to output the content of categories (the output tab allows you to download the results). I do the same for my work on Category:Harv and Sfn no-target errors. It would manually running the scan periodically though. -- LCU ActivelyDisinterested ∆transmissions∆ °co-ords° 17:58, 11 July 2023 (UTC)
 * Very belatedly, but FYI I'm now running a regular script to check on this - logs the current number and the most recent item. Usually drifts down by a couple of items a day. Will keep an eye out for sudden spikes which indicate a batch that could be addressed.
 * After some further investigation, it looks like the vast majority of these seem to be software version numbers that reference the release notes with a plain URL, and while it's straightforward to add a title to the reference manually, it's unfortunately a bit beyond my abilities to write up a bot to do it at scale. Andrew Gray (talk) 20:58, 8 August 2023 (UTC)

Edit request on 5 July 2023
Please copy the sandbox to the main module page. The new code fixes handling of database references (as described in my last reply in this discussion) and uses as the reference title when a URL is present in the reference but  is not. Janhrach (talk) 12:15, 5 July 2023 (UTC)

Using appropriate CS1 templates
It appears that Wikidata always uses Cite web. Sometimes that differs a bit from e.g. Cite news or other CS1 templates, though. Would it be possible to improve the module so that it recognizes when it's citing a newspaper/book/journal and uses the appropriate template? &#123;{u&#124; Sdkb  }&#125;  talk 04:23, 2 September 2023 (UTC)


 * Basically, there are two types of sources on Wikidata: ones using and ones using . Per Wikidata:Help:Sources, newspapers, books and journals should use the former option. Only citations containing P854 are formatted using Cite web. Janhrach (talk) 06:48, 2 September 2023 (UTC)
 * This touches on the discussion about mapping above. Currently, for something like a newspaper article, the correct procedure seems to be to use for the newspaper name and  for the article URL. Only using P248 would be an incomplete citation, as it would not lead back to the specific article. &#123;{u&#124;  Sdkb  }&#125;  talk 16:02, 2 September 2023 (UTC)
 * should contain not the newspaper item, but the article item. The Wikidata guideline says that every cited article should have its own item. Janhrach (talk) 06:45, 3 September 2023 (UTC)
 * @Janhrach, that would be wildly impractical for simple newspaper articles. &#123;{u&#124; Sdkb  }&#125;  talk 13:40, 3 September 2023 (UTC)
 * I understand, but that's a Wikidata policy. I am not sure, but I think I have read somewhere on Wikidata about a tool for generating newspaper article items on demand – it may be useful. Janhrach (talk) 19:06, 9 September 2023 (UTC)

Coordinates precision
Forgive me my laziness, I'm hoping someone will know the answer without digging too deep into the code. I would like  to return instead of How do I set the precision? I see it in the code, but not in any of the examples. Thanks. Ponor (talk) 15:13, 24 September 2023 (UTC)


 * The code probably uses the precision set in Wikidata, not in Wikipedia. Janhrach (talk) 14:38, 27 September 2023 (UTC)

Built-in citation needed function
Would it be possible to build in a mechanism for the references function of Wikidata to output a Citation needed tag if it does not come up with any references? For instance, when we use the template to fetch the number of students at a university, it's theoretically possible that someone in the future will update the (setting the more recent value to preferred rank) but not add references. If that happens, it'd be nice for there to be a citation needed tag rather than for the references function to just not display. &#123;{u&#124; Sdkb  }&#125;  talk 04:21, 4 October 2023 (UTC)
 * I'm seeing a use case for this sort of thing at Associated Students of Pomona College, where Module:WikidataIB should be used instead of this module, per the documentation and a related RFC. Using that module will take care of sourcing for you and will decline to show data when sourced numbers are not available. You could tell the module what to display or output a tracking category if if can't get a sourced number. – Jonesey95 (talk) 04:57, 4 October 2023 (UTC)
 * @Jonesey95, thanks for the reply; I'll look into converting to Module:WikidataIB there. The particular use case that prompted me to ask here was the first sentence of, where the number of students is used in the prose, so just blanking isn't an option. When I was updating the data for this semester on Wikidata, I tried waiting a moment to add the reference for the new data, hoping that I'd configured the  flags (or whatever it is I need to be configuring; perhaps I need to only allow  -ranked data?) well enough that it would identify that a reference is missing. But it just spit out all the references for the old data instead. The flags are a confusing enough part of the template that I just haven't been able to get them to work quite right. &#123;{u&#124;  Sdkb  }&#125;  talk 05:41, 4 October 2023 (UTC)
 * As far as I know WikidataIB does not yet display any references &mdash; Martin (MSGJ · talk) 09:06, 4 October 2023 (UTC)

Adding names to the coordinates list
I'm using GeoGroup on Misty Range where I pull the coordinates into the table of mountains using wikidata: e.g.  That works fine but when I click the OpenStreetMap link, the coordinates list on the left is showing "#1", "#2", "#3", "#4" for the names/labels for each coordinate. If you call coord directly and pass the name parameter, then OSM will display that name rather than "#1". However, I don't see how can set the coordinates name when I'm using wikidata to extract the coordinates. RedWolf (talk) 22:10, 4 September 2023 (UTC)


 * From a quick look at the source code of the module, it seems that is doesn't implement named coordinates. Janhrach (talk) 13:55, 14 September 2023 (UTC)


 * Thanks. I wonder if we could add a new named argument such as "coords_title" and then modify Config:getValue to append this argument (if given) to the URL it builds when datatype = 'globecoordinate'. RedWolf (talk) 17:19, 23 September 2023 (UTC)


 * I have created Module:Titled_coords and its helper template Titled_coords to address this issue. RedWolf (talk) 21:33, 20 October 2023 (UTC)

Problems with this module
I get it, semantic web shit is cool for nerds, but this doomed tech experiment is hurting Wikipedia instead of helping it. The people responsible should switch focus; their goal should be to help Wikipedia editors and not the likes of Google and LLMs and other cringe techbro buzzwords. I understand that the ideal solution, getting rid of wikidata, will not happen, so we should try to minimize the harm it is causing.

There are a bunch of problems with this module:


 * 1) This module shows errors, but it is not clear how to fix the errors unless you spend 73 hours trying to understand how it and Wikidata work. The solution should be two-fold:
 * 2) * It should be made clear on wikidata and in the article which attributes are missing/incorrect. Nota bene, currently this is explained in neither of those places. One or the other is not an acceptable solution. It should be explained in both places.
 * 3) * Someone should write a detailed tutorial/helppage. But a link to that is not enough; in addition we need specific instructions which piece of data is causing the problem.
 * 4) The warning messages are alarmist and displayed very prominently, even when it is an incredibly minor problem or not a real problem at all. A very large majority of the pages in Category:Module:Wd reference errors do not have a problem that is big enough to warrant such a obnoxious warning message.
 * 5) *For example: A reference url without a title (which appears to be optional at Wikidata) is handled poorly. For comparison,  produces: https://github.com/andresriancho/w3af/releases/tag/1.6.54. { { cite web }}: Missing or empty |title= ( help )  That still gives a clickable reference and the red message is less prominent. The Wikidata equivalent instead shows nothing. No explanation of what is wrong or how to fix it. All you get is this message that explains nothing and links to generic advice that isn't applicable: Error: Unable to display the reference properly. See the documentation for details.
 * 6) The message doesn't even link to the reference URL.
 * 7) The message falsely claims it is an error when no error has occured. There is just a missing piece of wikidata. 99.99999% of people who see that message are not willing and able to add that piece of wikidata.
 * 8) The message doesn't even link to the place on Wikidata where the problem is.
 * 9) The message uses crimson while other messages like the cite web template use #d33.

This means that people would have to read and understand all that documentation, find the location where the reference is inserted, figure out they have to click on the pencil icon, discover an entirely new and incredibly unuserfriendly interface on a separate website and figure out how to fix the error there, then go back to the article to see if they actually managed to fix the problem, discover they have not or that there are other problems and repeat the process (newsflash: 99% of Wikipedia editors won't do all that, why are you trying to force them to).

Even if you do something that should be simple, e.g. you add an infobox to an article, you get the message and no way to fix it. For example Infobox Swiss town causes problems for example in Lausanne, Geneva, Zug, Montreux, Bern, Solothurn (I got too lazy to find more examples).

I understand that this is people's baby and the WMF probably wasted a fuckton of money on it; but it should be clear that this is a net negative for 99% of editors at the moment. Things used to be so simple. More complexity is not an improvement. Polygnotus (talk) 04:00, 24 October 2023 (UTC)
 * That is quite a rant. I agree with one point, at least. In Lausanne, reference #2 displays "Error: Unable to display the reference properly. See the documentation for details." instead of displaying "https://www.pxweb.bfs.admin.ch/pxweb/fr/px-x-0102020000_201/-/px-x-0102020000_201.px/table/tableViewLayout2/?rxid=c5985c8d-66cd-446c-9a07-d8cc07276160", which is the source that supports the population figure. Showing only the error message is unhelpful. Showing the URL along with a more explanatory error message would be helpful; something like "Error: url requires title in Wikidata" (with a link to the relevant section of P1082 in the article's Wikidata entry) might lead ambitious editors to fix the actual problem. – Jonesey95 (talk) 04:26, 25 October 2023 (UTC)
 * On the problems you listed:
 * The relevant section is four-paragraph-long. While it doesn't directly describe how to fix a reference, it makes it clear when is the error printed. Everyone who doesn't understand can ask on this page. Yes, the messages could refer to specific parts of the reference which are invalid, I will work on that later. Note: this module is not directly related to Wikidata as a project, it is a Wikipedia module for rendering data.
 * Yes, the messages should be more specific. As for the messages being too alarmist, see this discussion. User:Trappist the monk wanted an error message if the reference is not renderable using CS1, and I agree with them.
 * See 2.
 * See 2.
 * Ok, this should also be fixed.
 * This is a minor issue fixable with an edit request.
 * In the end, all good arguments against Module:Wd can be summarized into following:
 * The error massage should be more specific.
 * Right now, I do not spend much time editing Wikipedia. The reference handling function should be cleaned up first. To fix it, it is needed to fix the testcases.
 * Janhrach (talk) 13:04, 26 October 2023 (UTC)
 * The citation (reference #2 in Lausanne) is renderable using cite web, though. It looks like this:
 * The error message is incorrect. This basic problem is not yet fixed. – Jonesey95 (talk) 14:44, 26 October 2023 (UTC)
 * By "renderable using CS1", I meant without errors. Also, I mentioned the phrase only in the last comment. The documentation is more specific.
 * I know the error message should say what extra properties does the reference contain, or which needed properties it does not, but I will fix that later. Maybe the module should leave reporting a missing title for now, as a temporary solution. Janhrach (talk) 14:59, 26 October 2023 (UTC)

Bot task: adding "title" to a reference url
It's Grumpy again; is there a bot that adds the title to a reference URL on Wikidata if its missing? It could simply scrape the HTML tag. The results wouldn't be perfect, but of course they would be better than the current situation. The bot could leave a short message on the relevant talkpage explaining this is a bot action and humans are invited to make improvements where they see fit. Polygnotus (talk) 16:58, 26 October 2023 (UTC)


 * I've asked on Wikidata. Janhrach (talk) 13:14, 27 October 2023 (UTC)
 * I see your post here but shouldn't we ask on WP:BOTREQ instead? Polygnotus (talk) 10:19, 28 October 2023 (UTC)
 * This is an intriguing idea, but it'd have to be handled with care. Bot messages on every talk where this happens is not handling with care (it's asking for "external links modified" 2.0). &#123;{u&#124; Sdkb  }&#125;  talk 13:41, 28 October 2023 (UTC)
 * (I assume you meant d:WD:BOTREQ) The page says that asking on the Project Chat is preferable, so I decided to ask there first. Janhrach (talk) 19:30, 1 November 2023 (UTC)

Edit request 15 December 2023
Description of suggested change: Add optional globalSiteId parameter, for getEntityId usage to get the QID from a non-enwiki sitelink

Diff: See Special:Diff/1190036817

Testcase: See Special:Diff/1190040466

Example: should yield Q1141358. Implemented on sandbox and verified all test cases pass. It should not affect any existing behavior, as it only adds a new feature. If there is no opposition to this change, I can implement it. --Habst (talk) 16:12, 15 December 2023 (UTC)


 * What is the use case? &mdash; Martin (MSGJ · talk) 16:30, 15 December 2023 (UTC)
 * @MSGJ, in my case, I wanted to use it to help translate foreign-language pages in my userspace. If I could easily (with a regex) translate all wikilinks in a dewiki article into  (or a template that would make this syntax shorter), I could combine that with LinkedLabel to effectively translate all the wikilinks in a dewiki article into their enwiki equivalent titles.
 * This is very helpful, because often times when translating an article, even if you understand the words, it can be difficult to know for sure what the appropriate target for a wikilink is. This can currently be done manually by clicking each wikilink in dewiki and then clicking "view wikidata item", but that's a painstaking manual process that only works one link at a time. --Habst (talk) 21:48, 15 December 2023 (UTC)

Wikidata reference errors at Taguig
There are two. I have to go to work soon and don't have time to figure out what's wrong over at Wikidata; can I irresponsibly pass ownership of this problem to someone here who understands how to fix it? Folly Mox (talk) 13:58, 12 January 2024 (UTC)


 * Well I've retrieved archived for the deadlinked 2015 and 2019 "poverty incidence" reference URLs at d:Q1643: 2015, 2018.I can't figure out how to edit these in at the Wikidata item (which is greylocked) even in desktop view. Folly Mox (talk) 03:40, 13 January 2024 (UTC)
 * I have fixed that, the reference had missing a title. Janhrach (talk) 08:32, 13 January 2024 (UTC)
 * Thank you for those fixes. Is there any way the error output of this module could be made a bit more specific? As a moderately technical editor with at least a basic understanding of where to look for Wikidata errors, I'm not sure how long it would have taken me to guess that the problem here was a missing title. Folly Mox (talk) 15:22, 13 January 2024 (UTC)
 * I have this in my to-do list, but I don't know when I'll do it. The problem is that the testcases are currently triplicated in three pages. I have started centralizing them, but it is tedious and repetitive, so I rarely work on this. I don't want to substatially modify the module until the testcases are ready. So until the testcases are centralized and the module is modified, I will answer editors' questions here. Janhrach (talk) 15:37, 13 January 2024 (UTC)

 * I have made a fix in the sandbox:

 * Looks good to me! My view is that it should be displayed the same as it would in CS1: I agree that the display in CS1 isn't ideal, but that's a larger issue for CS1 to deal with (and not a particularly dire one — having the specific location might help someone trying to verify the information, but it's not really going to harm anyone confused by it). Cheers, &#123;{u&#124; Sdkb  }&#125;  talk 23:01, 3 February 2024 (UTC)

Accessing titles from other Wikipedias
Still interested in this feature: given a wikidata Q-id and an ISO-639 code 'xx', return the title of the article at xx-wiki for that item. Perhaps as in this mockup:

There's also another editor interested in this; adding. Thanks, Mathglot (talk) 08:59, 14 February 2024 (UTC)


 * Theres a suggestion on the courtesy linked page to use >>, @Mathglot. Ponor (talk) 12:18, 16 February 2024 (UTC)
 * Thank you for your comment. I thought I missed a reply in that discussion or something, but it turns out that it came from a different discussion in section, and unfortunately I never saw that one. Also, I believed the response I got in the original discussion that it wasn't possible, so this is a very pleasant surprise. That's some eagle-eyed sleuthing; thanks again! Mathglot (talk) 23:12, 16 February 2024 (UTC)
 * Oh... thank you, @Mathglot, I learned something new too. This could be made into a separate template, if needed, so other people can find it:  //  → es:, or whatever you wanna to call it. It's a 10 minute job. Ponor (talk) 23:50, 16 February 2024 (UTC)
 * , yeah, and creating a template wrapper for it got added to my list the minute you replied and I saw it was workable. Only for me, it's more like a 2–3 hour job: ten minutes to code and test it, just as you say; then maybe 30-45' to write the doc page and maybe create a couple of template shortcuts, and another hour-plus or so to hunt down some RW examples in a few languages, and another hour or so to write the test cases page. Maybe I need to go to perfectionist jail for a while . I think it might need several redirect names; probably 'sitelink' is a good template name, but won't mean much to those who think 'foreign wikipedia title' and it's not obvious to me how to ensure it is findable; all your suggestions would be welcome.
 * As it happens, I'm deep into a wrapper creation right now: Draft:HasTemplate, which is going to be incredibly useful once it is released. It's got a backstory that is turning out to be a lot more complex than I ever expected; you can look at this discussion if you're curious, but fair warning: it really gets into the weeds on some things, so what I thought was going to be a terse, one-sentence, one-response discussion, is way more than that. (Feel free to wade in there, if you're not afraid of drowning in the details.) So, I will definitely write sitelink (or whatever we decide to call it) but you never know when something that seemed like a ten-minute thing at the time, turns out to have all sorts of little issues around it and goes on a lot longer, but I hope not! Mathglot (talk) 00:33, 17 February 2024 (UTC)
 * Well... I did something here: Template:Sitelink :) People will probably find it in its category, with other similar templates. Need to figure out how to make the foreign titles wikilinked, nothing like es:xxxx worked.
 * : (was cheap to get)
 * in any article should also work
 * Feel free to play further! And whoever's reading this. Ponor (talk) 01:22, 17 February 2024 (UTC)
 * Well, you just saved me ten minutes.  (I went ahead and updated the doc a bit more; see what you think.) I tested  at German Empire, and it worked perfectly, although there probably won't be much call for that. On the other hand, being able to use it from the associated Talk page would be very useful; I tested it at Talk:German Empire, and of course no big surprise that it returned empty. Any way it could be updated to detect namespace, i.e., switch to SUBJECTPAGENAME if it were on the Talk page? That would be very useful. Mathglot (talk) 02:52, 17 February 2024 (UTC)
 * @Mathglot: I have a few usecases on my 'other' wiki, for example when pointing readers to full documentation page for templates taken from enwiki, as in (ha! I used  here). I'm pretty sure something can be done about the talk pages, let me think about it. Should that be one wiki's talk page to another wiki's talk page or something else? One can always use QIDs and page titles, I wonder if adding more complexity to our little wrapper template would be worth it. Ponor (talk) 14:17, 19 February 2024 (UTC)

"Not enough memory" errors
At Comparison of cross-platform instant messaging clients, many of the table entries are displaying for various wikidata calls. I don't know anything about wikidata lookups, just passing along a message left on that article's talk-page. DMacks (talk) 04:13, 27 February 2024 (UTC)

A systematic way to avoid reference errors may be needed
I wonder, looking at just the "Comparison of ..." articles in (currently 1,181 pages), whether a change to the module might help fix some of these errors. Having an error message displayed instead of a reference, especially when nothing has changed in the Wikipedia article, is not good practice. It may be helpful for someone familiar with this module and with Wikidata's structure to look through a sample of these errors to see if a default setting like "prefer the most recent reference when a reference is requested" or a similar preference might help fix some of these errors. – Jonesey95 (talk) 18:55, 28 February 2024 (UTC)


 * The vast majority of the errors are caused by missing titles. The error messages were introduced into this module as a result of this discussion. I do agree that the current message, which doesn't specify what exactly caused the issue, is not good, and I plan to fix that in some time. However, this might be a complex problem, and I don't think I will have time for that in several months, at least.
 * As for the errors specifically, you might want to propose a change the module to not need titles in Wikidata references. In that case, you should read the mentioned discussion. Janhrach (talk) 18:51, 5 March 2024 (UTC)
 * A template-based reference that is missing a title is (a) incomplete, and should generate an error message, and (b) should generate an error message saying specifically that the title is missing. I hope that will not be difficult to achieve. – Jonesey95 (talk) 19:15, 5 March 2024 (UTC)
 * So we can do nothing about the number of the errors, except editing Wikidata. (Making a Wikidata bot adding titles to references is possible, but I can't do so.) As for no. 2, I am going to fix that sometime. Janhrach (talk) 19:59, 5 March 2024 (UTC)
 * A missing title is not an error and should not generate an error message. I asked about making a wikidata bot to add titles to references and all I got was Module_talk:Wd/Archive_1 6 months ago you also said "Right now, I do not spend much time editing Wikipedia". Why do we have to depend on 1 busy volunteers spare time to fix this important problem? Perhaps some of that $180.2 million of WMF revenue could be spent on something actually useful? Polygnotus (talk) 20:24, 5 March 2024 (UTC)
 * See WP:BAREURL. If not an error message, then at least append Bare URL inline to tag the reference for cleanup. – Jonesey95 (talk) 20:31, 5 March 2024 (UTC)

Reference call returns blank on te.wikipedia.org in one case
On te.wikipedia.org, the code used in infobox template for displaying reference is not working in some cases. Example url: https://te.wikipedia.org/wiki/%E0%B0%AA%E0%B1%8D%E0%B0%B0%E0%B0%A4%E0%B1%8D%E0%B0%AF%E0%B1%87%E0%B0%95:ExpandTemplates

template code that does not work

similar template code that works

On en.wikipedia.org at the URL https://en.wikipedia.org/wiki/Special:ExpandTemplates the code works for both cases.

The Templates and Modules involved are replicated on Telugu Wikipedia from English Wikipedia. I request help to address the problem.--Arjunaraoc (talk) 10:43, 20 February 2024 (UTC)


 * I think I have found out the cause of the issue, but I am not certain. Could you send me more examples of this bug?
 * I didn't have much time for Wikipedia recently, and I think I won't have in the immediate future, so don't expect this to be fixed in less than ~2 weeks. I will ping you when a fix is ready. Janhrach (talk) 17:19, 23 February 2024 (UTC)
 * @Janhrach, The code that I cited is used in 670+ pages on Telugu wikipedia. I found the  references call with P854, P1476 working properly (Q60165513 and corresponding Telugu Wikipedia page https://te.wikipedia.org/wiki/%E0%B0%87%E0%B0%82%E0%B0%95%E0%B1%8A%E0%B0%B2%E0%B1%8D%E0%B0%B2%E0%B1%81_%E0%B0%AE%E0%B0%82%E0%B0%A1%E0%B0%B2%E0%B0%82). So I updated almost all entries to use the working code.  So while this is not a priority, let me know when the fix is ready. Arjunaraoc (talk) 10:53, 27 February 2024 (UTC)
 * @Janhrach, Today I found another test case where the  code works on both English and Telugu Wikipeidas
 * Hope that helps.. Arjunaraoc (talk) 07:04, 28 February 2024 (UTC)
 * I think I know what causes the issue, but I am sure I won't have time to fix the issue in the next two weeks, if not more. Be patient, please. Janhrach (talk) 18:22, 5 March 2024 (UTC)

Getting Template:Update tracker working with qualifiers
I've been working on developing Update tracker and its child Update tracker item, templates for articles that use Wikidata that create a table for the talk page that lists which information needs to be updated (convenient for subjects like colleges that have a lot of data that needs updating every year).

I've gotten it mostly functional, except that I can't figure out how to get it to work with qualifiers (see the testcases). To function, it needs to call extra qualifier commands only when the qualifier or qualifier-value parameters are defined. I don't know of a way to conditionally add extra parameters, though, and keeping them blank causes an error.

Does that make sense? Anyone able to help? <span style="border:3px outset;border-radius:8pt 0;padding:1px 5px;background:linear-gradient(6rad,#86c,#2b9)"> Sdkb  talk 14:05, 10 April 2024 (UTC)


 * @Sdkb: what do you mean by "there's an error" (in your testcases)? Is it an error thrown by the module or is it just the wrong data that you're getting? I suppose you tried


 * Did you leave out the vertical bars in the last two variables? I did a quick test in your code, previewing your test cases while editing, and the previous code did return some values and no obvious errors.


 * I see another problem here / for . This:
 * → (current WD value is 2019)


 * seems alright. However, in
 * you'd expect the result to be 2020 (right?), but without any qualifiers the call returns the first of the two values of:
 * This would require a change on WD, another "applies to" or "rank: preferred", I believe.
 * This would require a change on WD, another "applies to" or "rank: preferred", I believe.
 * This would require a change on WD, another "applies to" or "rank: preferred", I believe.


 * Although, this does seem to work, so qualifier should be given with no value when there are other nonempty qualifiers for the property:
 * Ponor (talk) 12:56, 10 April 2024 (UTC)
 * Thanks for the reply, ! The error I'm referencing came from the fact that qualifier and qualifier-value are optional, and the most simple use case (the first two test cases) leave them out. The previous code I tried removed the equal sign if they were not present, causing the template to evaluate as, where the pipe and blank parameter at the end causes it to become blank. Curiously, using your more basic method, the template evaluates as  , which I didn't even try because I presumed it would produce even more of an error, but it actually seems to cause it to work as intended. So that resolves my problem, although I don't trust that blank equals signs will always be okay for Wikidata as it evolves in the future, so if there's a more durable solution that'd be good to know about. <span style="border:3px outset;border-radius:8pt 0;padding:1px 5px;background:linear-gradient(6rad,#86c,#2b9)"> Sdkb   talk 19:45, 10 April 2024 (UTC)
 * @Sdkb: glad it worked (wasnt' sure what exactly wasn't working). I don't think the blank equals sign will cause any problems; when there's nothing on its left, it should be discarded. If, however, you want to run some tests on your variables, you can try  Someone more familiar with parsers and stuff might tell us if there's a better way; something tells me there has to be a hard-coded = sign, and not its replacements.
