It's good practice though that the provided RDF graph contains statements that help us to figure out what the URI denotes. > and > > for all URI it is owl:sameAs the bits downloaded via HTTP > using that URI > > provided an HTTP get returns 200 ok? No. A 200 URI doesn't denote the bits coming back; the bits are a *representation* of the denoted information resource. One information resource can have many representations in different languages and formats. I suggest Roy Fielding's dissertation [1][2] as further reading, though it is slightly out of date now, given the httpRange-14 compromise.
