Thanks for the enthusiasm

I think that Yves Raimond thought about that possibility, you should probably contact him for more information.

Related to D2RQ, I don’t know if it is possible, but take care about some properties values: you need to do some transformation from the values that came from the RDB to the mapping into RDF. Check out the couple of SQL Procedure in the middle of the RDF View document for more information about these specific cases.

I will, but the problem right now is that Musicbrainz is quite huge, and that we had a performance isssue with some long row. Ivan is developing a fix that should be available soon to make this view performing well.

What I suggest is that as soon as this fix is available, I will setup a demo server where people will be able to send a series of SPARQL queries that I will write for that purpose. This demo server shoul be available next week, or in three weeks if the if is not finished next week (because I am in vacation from the 27 April to the 11 may in California).

So I will keep you updated via my blog. In the mean time, people will have another example of how the Music Ontology can be used

Take care,

Fred
