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. kc Karen Coyle wrote: > Ross Singer wrote: >> Right, but that's how it would work. If these resources were modeled >> in RDF, they'd have URIs.
