[Nepomuk] NMM: Representing music file, that contains several tracks.

[Roman Evstifeev]

Imagine a pretty long DJ-mix, represented on filesystem as one big
file(mp3, for ex.) with corresponding CUE-file. CUE describes several
tracks, that appears on that mix, their start position inside a file,
length, title...

How this can be represented in Nepomuk, assuming that user should be
able to assign tags and ratings to distinct tracks inside this mix?

I can imagine this would be something like this. but not sure:

nepomuk:/res/mixfile
      a nfo:FileDataObject .
      nie:url
         file:///home/mix.mp3 .
      nie:interpretedAs
         nepomuk:/res/mix .

nepomuk:/res/mix
      a nmm:MusicPiece .
      nie:isStoredAs
         nepomuk:/res/mixfile
      nie:hasLogicalPart
         nepomuk:/res/mix-track1
      nie:hasLogicalPart
         nepomuk:/res/mix-track2
      ....

nepomuk:/res/mix-track1
      a nmm:MusicPiece .
      nie:isLogicalPartOf
         nepomuk:/res/mix .


Am i right to represent the mix and it's tracks as nmm:MusicPiece's ?
Am i right to use nie:hasLogicalPart property to relate them?
How should i repersent a start position of the track inside the mix?
should i create a new property?
