Fabrice Florin, the WMF's head of Multimedia has just pointed me to an interesting meeting that will be taking place at the Hackathon of Wikimania:
https://wikimania2014.wikimedia.org/wiki/Hackathon#Structured_Data
*Structured Data *The Multimedia and Wikidata teams will host a roundtable discussion on our new Structured Data project https://www.mediawiki.org/wiki/Multimedia/Structured_Data, to implement machine-readable data for storing information about images and media files on Wikimedia Commons. We plan to develop this project together in fall 2014 and winter 2015, and it is likely to have a major impact on all aspects of multimedia usage, from viewing to uploads, editing, curation and using files on articles. We welcome the participation of all users familiar with using multimedia on Commons and other Wikimedia sites.
I think this sounds very much like the kind of thing that users of the GLAMwikiToolset (who are attending Wikimania) would be interested in knowing about - especially in the context of any future development in this field that will help bring WIkimedia Commons and Wikidata closer together. I'm sure this also fits well with the scope of Europeana's strategic interests too.
You can sign up at the link above (no specific time give just yet).
Sincerely, -Liam
