Go to the RDF WG website and read the current versions of the documents there, especially the MT and the N-triples spec. The WG some time ago decided that the graph syntax (as expressed in Ntriples) was primary, cf. http://www.w3.org/2000/03/rdf-tracking/#rdf-equivalent-representations Summary: Resolution: On 16th November 2001, the RDFCore WG resolved: * The WG agrees that: - the graph model which is the basis for the model theory - the n-Triples representation of an RDF graph - the diagrams of graphs used in documents such as the RDF Model and Syntax document are currently all equivalent * The WG resolves to maintain that equivalence (this is a statement of intent rather than a certified fact) * The WG notes that the RDF/XML syntax as currently defined is unable to represent an arbritary RDF graph. In particular, the RDF/XML syntax cannot fully represent a bNode which is the object of more than one statement. * The WG believes that extending the RDF/XML syntax so that it can represent all RDF graphs is beyond the scope of its current charter and resolves to postpone consideration of this issue. * The WG actions the editor of the RDF Syntax WD to include in that document a clear statement of the RDF graph structures that RDF/XML is unable to represent.
