Well, the document does not explicitly cite the Named Graph paper (Caroll et al. 2005), so I was mainly relying on intuition: if X's name is Y's name, then X and Y should be the same (as "names" on the SW are unambiguous names...). And btw, the Named Graph paper confirms that intuition: For every Named Graph ng ∈ N, we have I(name(ng)) = ng > Moreover, "an information identified" should be replaced by "an > information resource identified".

"entity" and "resource" have precise meanings when it comes to HTTP, and they are distinct. I should have written The RDF payload is an entity, not a HTTP resource; it is *not* identified by the URI of the corresponding HTTP resource. > Do you mean RDF Resource? "Resource" as in REST? see above > Everything can > be identified by a URI and everything is an RDF Resource. Of course... But you will agree that a g-box/graph-content, a g-snap/graph and a g-text/payload/entity are three different resources, and should therefore not be considered to have the same IRI. pa
