I have been following the LibDB
project, but have little actual knowledge of
programming or
FRBR for that matter. Having said that, I won't let it
keep me from giving my 2 cents.

The interface will essentially dictate that the
owner/cataloguer physically handle the item and enter
all works, expressions, and  manifestations correct?

Okay, now, after the initial data entry the other
identifiers mentioned (ISBNs, ISSNs, etc) will allow
said person to readily identify a given manifestation
of an expression so as to either:
a.Locate a physical copy
b.Cross-reference it with another work, expression, or
manifestation.
c.Replace a lost copy of a manifestation with an exact
copy.

Any other identifier (IMDB, MusicBrainz ID) would
allow one to reference information that is already
entered in LibDB(?). I say keep these "extra"
identifiers with the expression, or in the case of
ArtistID's (MusicBrainz example:
http://musicbrainz.org/artist/83d91898-7763-47d7-b03b-b92132375c47.html)with
the person or (corporate) body.
