The mo:myspace property points to a document (the myspace page), whereas we're asserting sameAs links between the same artists in Musicbrainz and Myspace. Try something like: PREFIX mo: <http://purl.org/ontology/mo/> SELECT ?myspace WHERE { ?x a mo:MusicArtist; owl:sameAs ?myspace. FILTER ( REGEX(str(?myspace), "^http://dbtune.org") ) } LIMIT 10 Cheers! yReceived on Thursday, 16 July 2009 09:33:25 UTC
