Hi Michael, Michiel Hildebrand wrote: > The rdfize is very nice. > It would be great if we could extend the api for batch processing. Yes, this sounds reasonable. Passing a URL parameter like a M3U [1] (a list of MP3 files), or an XSPF (XML file)[2] it could be an option. > > After uploading a mp3 file I get in return all the nice stuff about > the artist that was not in there before, however, I do not get the ID3 > stuff about the track. Good point! > Is this intended? Well, not really. I still need to implement some more stuff (the never ending story, you know!). So, all the ID3 tags I can extract (via python ID3 module), and their status in the mapping (ID3->MusicOntology, MO) are: * tags['title'] => DONE (already exported into RDF) * tags['artist'] => DONE (already exported into RDF) * tags['album'] => NOT DONE. I couldn't find a way to link a track to its album-release in the MO, only the other way around: "an album mo:has_track track". * tags['year'] => PENDING. My proposal is to link it with dc:date. * tags['comment'] => PENDING. My proposal is to link it with dc:description. * tags['genre'] => PENDING. My proposal is to link it with mo:Genre, but there are other proposals, like a SKOS taxonomy defining Musical Instruments [1], so probably doing the same for Musical Genres would be a good option (although nobody will agree on the taxonomy :-) ) * tags['track'] => PENDING. Probably link it with mo:trackNum [ BTW, Yves Raimond (Queen Mary University. London, UK) one of the creators of the MO is CC'ed, so he can comment whether I'm wrong! :-) ] + plus other attributes such as: duration of the track => PENDING. Probably link it with mo:signalTime Hopefully, the final version will include all these missing mappings in the code. But, as usual coding it takes much than expected... Thanks for the comments Michael. Cheers, Oscar [1] http://en.wikipedia.org/wiki/M3U [2] http://www.xspf.org/ [3] http://www.ivan-herman.net/Misc/2007/Mu.rdf
