Over the last year, we have seen some discussion about if and how Wikidata can be useful for Wikimedia Commons. One aspect of this is maintaining meta data as structured data. I think that the technology of Wikidata would be very useful for this, but that the meta data should be maintained on Commons itself. On behalf of the Wikidata development team, I just posted a proposal for this: https://commons.wikimedia.org/wiki/Commons:Wikidata_for_media_info We hope you regard this as an invitation to discuss the proposal and to identify use cases that we do not cover with it. Please use the proposal's talk page as a central place for discussion about Wikidata and media meta data. Please invite others involved with the Wikidata or Commons projects or otherwise interested in media meta data to take part in the invitation. Thank you, Daniel Kinzler _______________________________________________ Commons-l mailing list Commons-l(a)lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/commons-l

Hoi, Why not have tags (that are in effect references to Wikidata) they would in effect be searchable in any language.

Sure it's possible, no problem. The example properties are meant to be read that way.

You won't be able to run queries that span both system though, like "give me the birthdays of all people shown on pictures in category x". But that's the only big limitation i see.

Commons should be the interface to maintain the data. The actual data can be stored in a different location.

So I can link images of the church to https://www.wikidata.org/wiki/Q1545193 (item on Wikidata)? I don't feel like having duplicate systems......

In the long run we should probably get rid of the categories.
