There exists a bf:Instance identified by URI "http://bibframe.org/resources/BKw1416525962/779299instance18".

I'm not sure that the notion of aboutness is all that helpful, here. It's another case of RDF/XML leading us astray with the hypnotic allure of ghostly semantics that don't really obtain.

I think we use it (here) frequently and I don’t think it has ever been used (here, or in BIBFRAME) to mean rdf:Description. Is there another expression, that means “an RDF description” that you prefer? (We can always go back to calling it an “RDF record”.)

Note, for example, that rdf:Description isn’t manifested in other RDF serializations like a real class would be. It drops out.

I want to try to explain my view of what a BIBFRAME resource is, in simple terms, without using terminology that I don’t think we have agreed-upon definition for, such as “real-world-object”, “thingy”, and “r-ball”. (I have no idea what an r-ball is, only a vague idea what a thingy is, and I know what my definition of an RWO is but am not sure we all agree.) If I use any term that anyone thinks does not have a commonly agreed-upon definition, please call me out.

> Rob says (I’m paraphrasing) “you can’t have one single URI identifying both the thing and it’s description” . But we don’t. These are two distinct URIs. The trick is, if you click on the “thing” you get the description, i.e. you get RDF, and that’s because that’s what web architecture and linked data principles say is supposed to happen: if a URI identifies a resource which is an abstract concept, if you dereference that URI there should be an HTTP 303 re-direct to an RDF description of that resource.
