I just started a D2R mapping for Musicbrainz, which allows to create a SPARQL end-point and to provide linked data access out of Musicbrainz fairly easily. A D2R instance loaded with the mapping as it is now is also available (be gentle, it is running on a cheap computer :-) ).

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 ;
  • Linked with DBpedia for places and Lingvoj for languages

There is still a lot to do, though: it is really a start. The mapping is available on the motools sourceforge project. I hope to post a follow-up soon! (including examples of funny SPARQL queries :-) ).

Update: For some obscure port-forwarding reasons, the SNORQL interface to the SPARQL end point does not work on the test server.

Update 2: This is fixed. (thanks to the anonymous SPARQL crash tester which helped me find the bug, by the way :-) )
