I'd rely on the Barcode for later grouping of discs but I'd store the
disc catalogue #. The album catalogue number could be put in an
annotation. I'd do it this way because the day we will create an
object to grop discs, we won't have to change anything to the data
stored in the discs release events. All we will have to do is group
discs by barcode and check in the annotations to get the album
catalogue number.
1) not all musical releases have barcodes. i don't think we should
rely on it for anything.
2) from a label point of view, the set cat# is most important. eg,
most vinyls will have different cat#s in the run out grove (eg 1
1234-A vs 1 1234-B) but that is pretty much extra info. the only time
the specific cat#s of a CD disc would be useful is if you owned 1
disc, without the cover. that way you'd be able to track down what set
the disc belonged to.
if anything goes to the annotation it's the individual disc cat#s,
IMO. we must must must store the album cat#, if our label support is
gonna be useful.
