Hi Chris, > ... > <dc:relation> > <dcq:references> > <dcq:URI> > <rdf:value>http://mkdoc.com/</rdf:value> > </dcq:URI> > </dcq:references> > </dc:relation> there is no class dcq:URI defined in our proposal. The concept of URI is implicitly contained in RDF, so there is no need to define such a class. Just use rdf:resource="..." instead. It may be necessary to define such a class in a non-RDF implementation of qualified Dublin Core. regards, stefan
