For example, in your schema for Dublin Core you define elements of type string. The problem with this is that Dublin Core elements can also be used like this: <rdf:Description dc:title="The story of q" /> or this: <rdf:Description> <dc:title rdf:resource="#q"> </rdf:Description> etc. So an XML schema (which deals with the format of the actual XML) isn't as useful as an RDF schema (which deals with the underlying abstract model). -- [ Aaron Swartz | me@aaronsw.com | http://www.aaronsw.com ]
