Sorry, spoke/wrote too soon. FRBR at vocab.org isn't using the FRBR 
attributes either. And it does have the entities as classes. I'm still 
not sure how one can model a relationship between RDA or bibo properties 
and FRBR Group 1 entities and their properties. RDA tries to assign 
descriptive properties (like 'title' and 'place of publication') to 
particular FRBR Group 1 entities, which I think doesn't work.

OK, I'm off to think about this some more. With some BIG pieces of paper.
