User:Bjohas/ShareAlike

We're creating Creative Commons guidance for Schools (that will be licensed under CC-By), in which we're trying to explain details of ShareAlike. This page is for a discussion of the ShareAlike licence, and what you can and cannot do. This is not advice, but it's meant for community discussion, so the statements below may or may not be true!!

Let's assume that the work is CC-By-SA licensed, http://creativecommons.org/licenses/by-sa/4.0/legalcode.

= (1) I can do this, and the work stays under the same licence and attribution (no new work produced) =


 * 1) Make copies of the work, e.g. copying a lesson plan, copying worksheets, etc.; printing the work onto paper
 * 2) Share these copies it with others
 * 3) Post it online - on the schools website or school intranet.
 * 4) Perform the work (e.g. perform music or plays).
 * 5) Convert the format (e.g. from Word docx to OpenOffice odt, from odt to PDF; from jpg to png; from wav to mp3; from wmv to mp4)
 * 6) Resize an image (from 600x400 to 60x40)
 * 7) Transcode a movie (from high bitrate to low bitrate)
 * 8) Convert an unencrypted DVD to a movie (e.g. mp4)
 * 9) Play an unedited video in the background of a live concert

= (2) I can do this, but it generates a new work, and if I publish the new work, I need to licence the work as CC-By-SA =


 * 1) For images or diagrams: crop, adjust colour (e.g. black and white), add text or other graphics to the image/diagram
 * 2) For text:
 * 3) Edit the text, e.g. add/remove words
 * 4) Translate the text.
 * 5) For movies: When using an audio track in a movie, the movie is classed as a derivative work, and needs to have the same SA licence.
 * 6) For movies: I.e. if a Cc-By-SA  image is included, then the whole movie needs to be CC-By-SA.
 * 7) Translating a short story from one language to another
 * 8) Photoshopping a picture to add to or alter its original elements
 * 9) Using a sample from one song to make new song

= (3) I can do this, and do not need to licence the resulting work as SA =

Without the work being "translated, altered, arranged, transformed, or otherwise modified", and with the work being attributed (which needs to include the source, author, and original licence) I can
 * 1) reproduce the work on a website (the website itself does not need to be CC-By-SA licensed)
 * 2) include the work in a document (e.g. text document, presentation, pdf, ebook; the document does not need to be SA licensed)  (See User_talk:Bjohas/ShareAlike)
 * 3) include a short story in a collection of short stories
 * 4) meaning that I can create a zip file that collects the individual pdfs
 * 5) meaning that I can create a single pdf with all the stories in it.

= Questions =


 * 1) Are all of the above correct?
 * 2) Are all of the above correct for all versions (1.0 - 4.0) of the SA licences? In all countries?
 * 3) Is 2.4 ("For movies: I.e. if a Cc-By-SA  image is included, then the whole movie needs to be CC-By-SA.") correct? (I think yes, because of "Adapted Material is always produced where the Licensed Material is synched in timed relation with a moving image.")
 * 4) Is 3.2 ("include the work in a document") correct? (I think yes, see User_talk:Bjohas/ShareAlike, and licence extracts below: "derived ... and ... translated, altered, ...")
 * 5) Are the terms for ND the same? i.e. (1) and (3) can be done under ND, but (2) cannot.

Additional questions:
 * 1) What if I record an academic lecture, and the slides contain SA licensed material?
 * 2) In 1.5, what if the DVD is encrypted with the usual DVD encryption, but the DVD content is CC licensed? Can I use DVD decryption software to encode to mp4?

The relevant bits of the licence, http://creativecommons.org/licenses/by-sa/4.0/legalcode would appear to be:

''Section 1 – Definitions. (a) Adapted Material means material subject to Copyright and Similar Rights that is derived from or based upon the Licensed Material and in which the Licensed Material is translated, altered, arranged, transformed, or otherwise modified in a manner requiring permission under the Copyright and Similar Rights held by the Licensor. For purposes of this Public License, where the Licensed Material is a musical work, performance, or sound recording, Adapted Material is always produced where the Licensed Material is synched in timed relation with a moving image. ''

''Section 2. Scope (a) 4 Media and formats; technical modifications allowed. The Licensor authorizes You to exercise the Licensed Rights in all media and formats whether now known or hereafter created, and to make technical modifications necessary to do so. The Licensor waives and/or agrees not to assert any right or authority to forbid You from making technical modifications necessary to exercise the Licensed Rights, including technical modifications necessary to circumvent Effective Technological Measures. For purposes of this Public License, simply making modifications authorized by this Section 2(a)(4) never produces Adapted Material. ''
