Rather than FRBR (which isn't that great, even for books), I'd look at how MusicBrainz and/or Freebase do things (they're pretty closely aligned, I think). Composition https://www.freebase.com/m/048bf9 Single https://www.freebase.com/m/01hmyv3 Sticky Fingers album https://www.freebase.com/m/01hmy3x primary album release https://www.freebase.com/m/03436qv Brown Sugar track on that release https://www.freebase.com/m/0l44n1g Brown Sugar recording which appears as that track on the album https://www.freebase.com/m/0frvqbn Each of these, except for the release-recording connector, is linked back to the corresponding entity on MusicBrainz, so you can see how they present the same information. The advantage of following a schema like MusicBrainz is that you get to take advantage of the knowledge of domain experts who've thought deeply about how to structure this information. This is something like the third major revision of their schema, over many years, so a *lot* of thought has gone into it. The advantage of the Freebase view is that it shows how the music specific piece integrates with other general knowledge elements and external information sources like Discogs <http://www.discogs.com/release/1489020> in a manner similar to what Wikidata would want to do. https://www.freebase.com/music/album?schema= https://www.freebase.com/music/release?schema= https://www.freebase.com/music/recording?schema= https://www.freebase.com/music/recording?schema= https://www.freebase.com/music/artist?schema= https://www.freebase.com/music/composition?schema= https://musicbrainz.org/doc/MusicBrainz_Database/Schema Tom On Thu, Dec 31, 2015 at 10:32 AM, Federico Leva (Nemo) &lt;nemowiki(a)gmail.com&gt; wrote:
