There are two resources modeled: http://viaf.org/viaf/111894442/#skos:Concept and http://viaf.org/viaf/111894442/#foaf:Person (well, obviously there are more than that minted at: http://viaf.org/viaf/111894442/rdf.xml) the first would appropriate for biographies of Bob Dylan, etc. the latter for works by him. -Ross.
