I believe within RDF you can only merge to produce two sets of statements: <rdf:Description rdf:about="http://www.w3.org/TR/html4/strict.dtd" dc:creator="Dave Raggett" dc:creator="Arnaud Le Hors" dc:creator="Ian Jacobs" dc:publisher="World Wide Web Consortium" /> <rdf:Description rdf:about="urn:publicid:-:W3C:DTD+HTML+4.01:EN" dc:creator="Dave Raggett" dc:creator="Arnaud Le Hors" dc:creator="Ian Jacobs" dc:publisher="World Wide Web Consortium" /> but if you step up to OWL you could use owl:sameIndividualAs (or owl:equivalentTo) <rdf:Description rdf:about="http://www.w3.org/TR/html4/strict.dtd" dc:creator="Dave Raggett" dc:creator="Arnaud Le Hors" dc:creator="Ian Jacobs" dc:publisher="World Wide Web Consortium"> <owl:sameIndividualAs rdf:resource="urn:publicid:-:W3C:DTD+HTML+4.01:EN" /> </rdf:Description> (or vice versa) so the graph is pretty dull really - just another property hanging off the resource.
