Personally I prefer the first form except for the 'Owner' versus 'owner' distinction which is lost to me. Indeed, why not: <Paintings rdf:about = "WMAA.70.1650"> <Title>(Self-Portrait)</Title> <owner> <Organization rdf:about = "http://www.amico.org/laf/entities/whitney_museum_of_american_art"> <name>Whitney Museum of American Art</name> </Organization> <accessionNumber rdf:resource = "70.1650" /> <place>New York, New York, USA</place> <credit>Josephine N.
