Flickr & MusicBrainz Machine tags: If you’ve got it, flaunt it

From Sander van Zoest at Uncensored Interview, a convention for representing MusicBrainz identifiers using Flickr’s Machine Tag mechanism.

Example:

A photo of Matthew Dear, tagged as follows:

It also includes a Wikipedia identifier which could be used to link to DBpedia (though this might duplicate information also available within MusicBrainz’s advanced relationships system). There must be many 1000s of artist photos on Flickr, perhaps we’ll see tools to improve their tagging so they can be re-used more easily…

MusicBrainz SQL-to-RDF D2RQ mapping from Yves Raimond

More great music-related stuff from Yves Raimond. He’s just announced (on the Music ontology list) a D2RQ mapping of the MusicBrainz SQL into RDF and SPARQL. There’s a running instance of it on his site. The N3 mapping files are on the  motools sourceforge site.

Yves writes…

Added to the things that are available within the Zitgist mapping:

  •  SPARQL end point
  •  Support for tags
  • Supports a couple of advanced relationships (still working my way  through it, though)
  • Instrument taxonomy directly generated from the db, and related to performance events
  • Support for orchestras

This is pretty cool, since the original MusicBrainz RDF is rather dated (if it’s even still available). The new representations are much richer and probably also easier to maintain.

Nearby in the Web: discussion of RDF views into MySpace; and the RDB2RDF Incubator Group at W3C discussions are getting started (this group is looking at technology such as D2RQ which map non-RDF databases into our strange parallel world…)
