Change Details

**Main components:** * Wikimedia Badges **Problem:** The sidebar link to Wikimedia Commons on various Wikipedias currently uses `P373` ("commons category"). It would be better to use the interwiki sitelinks to Commons instead. This is one of the blockers for the eventual deletion of `P373` ("commons category") from Wikidata - see the ongoing discussion at https://www.wikidata.org/wiki/Wikidata:Properties_for_deletion#Property:P373 **Solution:** To use the interwiki sitelinks to Commons the logic would be: 1) If there is a sitelink to Commons in the attached Wikidata item, use that (optional: unless it is to a gallery page) 2) If there is a `P910` ("topic's main category") value, follow that to the category item and use the sitelink to Commons from there 3) If there is a `P1754` ("category related to list") value, follow that to the category item and use the sitelink to Commons from there 4) If there is a `P373` ("commons category") value use this as a last fallback 5) Otherwise, display nothing. This follows the logic of the "_getCommonslink" function of https://commons.wikimedia.org/wiki/Module:WikidataIB - which is used to display the links in https://en.wikipedia.org/wiki/Template:Commons_category . **Notes:** * As this is specific code used for the Wikimedia projects only, it should probably sit in the Wikimedia Badges extension, like the current `P373` code (see T94989). * The exact logic for getting “the” `P910`/`P1754` value is the same as in the current `P373` code (first string-valued best-rank statement). **Acceptance criteria:** [] This works as described (see "solution"). [] This needs to be able to cope with P373 being deleted without breaking things (and ideally it should be easy to remove the P373 fallback in that case). **Open questions:** * Should we include P373 as a last fallback (before it is removed)? **Community communication:** * Announce to the community in our wiki summary while we work on it. * Announce on project chat / let Mike announce.
