The Music Ontology Specification provides main concepts and properties fo describing music (i.e. artists, albums, tracks, but also performances, arrangements, etc.) on the Semantic Web.
While dealing with this issue at the moment, I raised this agonized question one more time at the MBZ dev IRC channel:
<zazi> one release can different catalog numbers
<zazi> or
<zazi> a catalog number can have different releases
<zazi> ?
<ocharles> A release has multiple release labels (label/cat no pairs)
<reosarevok> zazi: all the labels and catalog numbers for a single release are supposed to be related to the same country-date (that is, the actual CD or whatever was published as a cooperation by two or more labels, or the label gave it several catalog numbers)
<reosarevok> (also, a catalog number can be in different releases, for example if the label gave the same catalog number to the CD and vinyl editions)
<reosarevok> (but AFAIK it doesn't link them in any way in the database, it just means they happen to have the same info in that field)
<zazi> yep, that's what I thought as well
My conclusion is that we should move the domain of mo:catalogue_number and mo:label to mo:ReleaseEvent instead of mo:Release. Any opinions?
