I am right that such a pointer to external data would have to be a literal? The way I read the XMP standard is that only literals, blank nodes, rdf:Bag and rdf:Seq are allowed as object of a triple. This would rule out standard options like: <this_document> rdfs:seealso <rdf_document_about_pdf_document> <this_document> owl:sameAs <pdf_document_uri> Which would enable agents to find and regognize RDF data about the document.
