LCSH, MESH, or even a local subject heading set).  The question then is how to describe the subject itself.  SKOS is currently a default in this area, we should start to lobby those that manage these to start adopting Schema in addition to SKOS.

However to handle this you will always be disenfranchising some identifier backing group.  Isbn seems to of got in because it is know by everyone, oclcnum is obvious from where I sit (but that does not make it right).   I think we (in all of Schema, not just the bib domain) need an identifier Type with properties of ‘identifierValue’ and ‘identifierType’ - which could handle either an enumerated list or at least well known identifier names.
