I am reading the RDF Semantics document carefully, and am having a little trouble with the following passage http://www.w3.org/TR/rdf-mt/#instlemprf [[ To be precise, a Skolemization of E (with respect to V) is a ground instance of E with respect to V with a 1:1 instance mapping that maps each blank node in G to a URI reference that does not appear in G (so the Skolem vocabulary V must be disjoint from the vocabulary of E) ]] It does not seem to be explained what the relation between E and G is in the above passage. To me it would make sense if E=G, ie: [[ To be precise, a Skolemization of E (with respect to V) is a ground instance of E with respect to V with a 1:1 instance mapping that maps each blank node in E to a URI reference that does not appear in E (so the Skolem vocabulary V must be disjoint from the vocabulary of E) ]] What have I misunderstood?
