To me, "describes" and "represents" are pretty clear:

A URI can represent something. It, in itself, does not describe
anything, since it's just a URI. A document can describe something,
but does not represent anything. A URI can potentially represent the
document you get when you dereference it, or it could represent the
thing that is described when you dereference it. The document can
usually clear that up (is that URI a foaf:Document or foaf:Person, for
instance?).

The question is, is a BOB more like a document, or more like a URI? I
had assumed it was more like a document, since people had been
discussing how it would "contain" assertions sufficient to identify
the entity in question.
