RDF-ISSUE-85 (identity-of-values): Update RDF Semantics to distinguish between the identity of values and the (numeric) equality of values to be in line with XSD 1.1 [RDF Semantics] http://www.w3.org/2011/rdf-wg/track/issues/85 Raised by: David Wood On product: RDF Semantics XSD 1.1 distinguishes between the identity of values and the (numeric) equality of values. As far as [Alex] can tell, RDF Semantics is defined strictly in terms of identities (I would appreciate confirmation of this from one of the editors). To avoid confusion, it might be worth noting this distinction in the section on datatype entailment and explicitly stating that datatype entailment deals with identity and not equality, if that is indeed our position. [For SPARQL, pattern matching deals with identity and the '=' operator deals with equality.] The RDF WG Charter says that we must, "Consider reconciling the core RDF(S) documents with semantic features and extensions defined by other W3C Recommendations since 2004". Richard conducted a poll to determine how WG members felt about various interpretations of literals. This poll was conducted as part of the discussion of string literals (ISSUE-12), but also asked about numericals.
