User:Daniel Mietchen/Talks/JATS-Con Impromptu 2013/Keywords


 * OAMI uses keywords to assign Wikimedia Commons categories to media objects


 * JATS describes two main methods for tagging keywords:
 *  and any of  , , , , or 
 *  /  /  

Problems with JATS

 * Paradox of choice. There are too many options, with no clear guidance on the best practice for machine-readability / interoperability. (See all the examples from the  and  documentation.)


 *  cannot be applied to individual media or data files (but see this comment on the NISO site)

Problems with tagging

 * Bad keywords: typos, misspellings, etc. For example, the Wikimedia Commons category "Biophysic al simulations"


 * Inconsistent use of the @subj-group-type attribute. (examples)


 * Inconsistent use of the @kwd-group-type attribute. (examples)
 * No keywords or subject tags at all
