The following claim from RDF Semantics, Section 0.3, is incorrect: In particular, any graph obtained by replacing all blank nodes by new blank nodes not in the original graph is an instance of the original and also, by inverting the mapping, has it as an instance. By our convention, such isomorphic graphs are considered to be identical. To see this consider the ``original'' graph a:b c:d _:a . a:b c:e _:b . and the ``new'' graph a:b c:d _:c . a:b c:e _:c . peter
