I brief update status.
1) I just fix multiple performers bug in flac analyzer.
2) nmm:albumArtist seems to be related to DB structure and is not a coding
bug. I just added nmm:albumArtist to SDO and now there is a nmm:albumArtist
in nmm:MusicAlbum. This is the code I added:
nmm:albumArtist
a rdf:Property, nrl:DefiningProperty ;
rdfs:subPropertyOf nco:contributor ;
rdfs:label "album artist" ;
rdfs:comment "Album artist" ;
rdfs:domain nmm:MusicAlbum ;
rdfs:range nco:Contact .
I will upload a patch to Review Board for the first one but, what must I do
with the second one?
