I hadn't raised it myself in the metadata context for exactly that reason. But certainly there is a lot of overlap between https://www.mediawiki.org/wiki/Files_and_licenses_concept and https://www.mediawiki.org/wiki/Multimedia/Structured_Data Even if the goals aren't completely the same, if nothing else, some of the schemas should really be made to line up. > The plan for the structured data project is to create Wikidata properties >> for legalese, install Wikibase on Commons (and possibly other wikis which >> have local images), make that Wikibase use Wikidata properties (and >> sometimes Wikidata items as values), create a new entity type called >> mediainfo (which is like a Wikibase item, but associated with a file), and >> add legal information to the mediainfo entries. >> >> Part of that (the Wikidata properties) could be reused for articles and >> other non-file content - the source, license etc. properties are generic >> enough.
