MotivationEdit

Sometimes it is important to be able to indicate which particular revision of a Commons image a Wikidata or SDC statement refers to. For example, georeferencing information will fail to be correct if an image has been cropped. A mechanism is therefore necessary to be able to specify a particular version of a Commons file.

  •   Comment This is not going to work properly, because, when someone will upload a new version, the file will change its version number, but the value in the property may stay the old one. Moreover, there was a discussion with WMF team, that it's not possible to track different versions so they cannot be stored in Wikidata. --Juandev (talk) 20:21, 29 September 2019 (UTC)
    • @Juandev: The whole point is that we want the property to point to the old version of the image, because that is the one that the georeferencing was done against, not any later reupload that may potentially have been cropped. Jheald (talk) 22:15, 13 October 2019 (UTC)
  • I think the (current) samples give the revision of the file description page, not the image version. --- Jura 09:35, 13 October 2019 (UTC)
