Hi Primavera, I'm no admin in Commons, but I think I can say few things. As you know, Commons, as the all other Wikimedia projects, is based on MediaWiki, which cannot manage metadata properly (i.e. in dedicated databases).
So far, we just have parsers and bots which read our templates (in Wikipedia as in Commons) to retrieve some metadata. Another way is to work directly with the dumps (it happens with DBpedia, I think). As far as I know, it has been discussed *many* times to upgrade/shift to a more granular, structured system, but right now there is not. There are some extensions in MediaWiki that could help (as Semantic MediaWiki), but they are not implemented for security reasons. People interested in GLAM partnerships (Galleries, Libraries, Archives, Museums) discuss often about the need of managing metadata, but it's a big and not easy issue, involving the very core of MediaWiki. (I'm the guy obsessed in having an OAI-MPH extension for MediaWiki, so I understand you perfectly :-) So, the only thing you could do is ask our developers/tecchies for bots and other fancy script which currently are doing a similar job. Aubrey PS: to Commons admins: please corret me if I siad something wrong, but this is the picture I have. 2011/8/19 Primavera De Filippi <[email protected]>: > Hi all, > I write to you on behalf of the public domain working grouf of the > Open Knowledge Foundation.
