Hi Ross,
I really need to polish the presentation of some of this... That email
was written very quickly before I had to run out of the office. But
anyways...

In the case of FRBR this was to avoid confusion since coopting its
classes means using them in ways that have different meaning.
frbr:Manifestation implies a frbr:Expression whereas obp:Manifestation
doesn't. Making a new obp:Work also happens in places where FRBR would
expect simply a new frbr:Expression.

I think you're right here. There don't seem to be much in the way of
domain/range restrictions on these properties so I don't see why they
couldn't be used.
For the W3 LLD list in the crosspost -- please let me know if this is
inappropriate for the list, might be getting ahead of ourselves a bit.
This is meant specifically in the context of the use case that is taking
a MARC record and turning it into RDF.
As it is, it looks like a MARC record at a minimum consists in:
* one xyz:Manifestation
o one dc:publisher
* one (implied) xyz:Work
o one or more dc:contributor (or sub-properties like author,
translator, etc)
o one or more identifiers, bibo:isbn bibo:issn etc
o one or more dc:subject from a controlled vocabulary
Cheers,
