Hello all, As you may know, WMF, WMDE and volunteers are working together on the structured data for Commons <https://commons.wikimedia.org/wiki/Commons:Structured_data> project. We’re currently working on a lot of technical groundwork for this project. One big part of that is allowing the use of Wikidata’s items and properties to describe media files on Commons. We call this feature federation. We have now developed the necessary code for it and you can try it out on a test system and give feedback. We have one test wiki that represents Commons ( http://structured-commons.wmflabs.org) and another one simulating Wikidata ( http://federated-wikidata.wmflabs.org). You can see an example <http://structured-commons.wmflabs.org/wiki/MediaInfo:M13> where the statements use items and properties from the faked Wikidata. Feel free to try it by adding statements to to some of the files on the test system. (You might need to create some items on http://federated-wikidata.wmflabs.org if they don’t exist yet. We have created a few for testing.) If you have any questions or concern, please let us know. Thanks, -- Léa Lacroix Project Manager Community Communication for Wikidata Wikimedia Deutschland e.V.
