For example, I've abused the Music Ontology modeling in the past by creating my own term to specify the composer associated with a classical music recording http://open.vocab.org/docs/composer (which de-refs to a nice html page in browser or an rdf description w/ appropriate headers all thnx to open.vocab) -Kurt J
