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 .
This looks good. I am only concerned about having performer and producer on the tracks and artist on the album. Shouldn't that be in sync somehow? After all an album is also produced, right? A compilation has a producer and each track has a possibly different producer...
I will upload a patch to Review Board for the first one but, what must I do with the second one?
The normal approach is to create a ticket at https://sourceforge.net/apps/trac/oscaf/

Solution: * 0 to n nmm:albumArtist resources must be added to nmm:MusicAlbum. * 0 to n nmm:performer resources must be added to nmm:MusicPiece. 2) Albums: * there is no url in nmm:MusicAlbum so two different albums with same name are considered one unique resource. * determine album url is tricky, you need to obtain the url from a track, a method complicated because previous problem. Solution: * add nie:url to albums. * two albums with same name but different path are different albums. This have a side effect with sets if sets are in different paths, but I think is better that sets are considered different albums, than two different albums are the same resource. On the other side, this could be handle with some smart path detection assuming some kind of organization with paths. Other solution could be using nmm:albumArtis to determine if two albums are different but, then we have the problem with various artists compilations. * added nfo:depiction as a cover, an image that could be handled by Bangarang or Nepoogle. * maybe more nfo:depiction for scans? 3) Genres: * mp3: is not working. * flac: works fine, supporting unlimited genres. Solution: * bug with mp3 files must be fixed. 4) Sets: * there is no total tracks per set. * the total tracks is equal to the total tracks number in the last track scanned. Solution: * a solution similar as seasons in tvshows. * a total tracks and a total tracks per set must be handled. I'm only using flac and mp3 so the same or other issues could be in other music formats. Sets problems is a minor issue, but the other three, must be fixed. As practically all my music is in flac format I will try to fix problems 1 and 2 in flac analyzer, I'm crossing my fingers because is C++, but I wish to hear comments/suggestions before begin to code. -- Best wishes, Ignacio -- Best wishes, Ignacio _______________________________________________ Nepomuk mailing list [email protected] https://mail.kde.org/mailman/listinfo/nepomuk
