Hi! A lot of people these days have CDs stored as one big .FLAC file, with a .CUE sheet listing the offset of each actual track. To get Tracker to recognise these requires some sort of ontology addition to express the track offsets. As far as I can see, the best solution is the following: each logical track is a nmm:MusicPiece resource with its nie:uri pointing to the one .FLAC file, and a new nfo:audioContainerOffset property that specifies the offset in samples of the track into its file.
Is this the best approach? The name of the property and its unit also need nailing down - samples are the most accurate unit, and they apply to basically all types of audio other than .mod files, but of course that makes the property audio-specific (hence the suggested name nfo:audioContainerOffset). In terms of implementation, I'm going to have to add it to the libflac based extractor, because there's a whole lot of work to be finished up before gstreamer can handle this sort of thing[1]. Also, does anyone know the best way to contact nepomuk upstream these days? the only committer to the shared-desktop-ontologies[2] seems to be Sebastian Trueg (of KDE), they don't seem to have their own mailing list so I think I'm going to ask him where is best to get their opinion. Thanks!
