Mark, I prefer the modelling with the explicit accession record (method 2). It leaves open the possibility of annotating it with other information, like who/what/when/why like the 'credit' property that Kevin points out. With both approaches, it is now possible to separate out the Organization information as it is independent of the record. A separate record of organizations with the URI (already specified) reduces the size of each work item record.

Hopper Bequest</credit> <accessionNumber rdf:resource = "70.1650" /> </Organization> </owner> </Paintings> when several of these records are merged, the relationship between the painting and the accessionNumber is lost, because accessionNumber is a property of http://www.amico.org/laf/entities/whitney_museum_of_american_art, not the painting. There are two alternative ways of encoding this to avoid this: <Paintings rdf:about = "WMAA.70.1650"> <Title>(Self-Portrait)</Title> <owner> <Owner> <ownerIdentity> <Organization rdf:about = "http://www.amico.org/laf/entities/whitney_museum_of_american_art"> <name>Whitney Museum of American Art</name> <place>New York, New York, USA</place> <credit>Josephine N. Hopper Bequest</credit> </Organization> </ownerIdentity> <accessionNumber rdf:resource = "70.1650" /> </Owner> </owner> </Paintings> or alternatively <Paintings rdf:about = "WMAA.70.1650"> <Title>(Self-Portrait)</Title> <accessionObject> <AccessionNumber> <organization rdf:resource="http://www.amico.org/laf/entities/whitney_museum_of_american_a rt"/> <accessionNumber rdf:resource = "70.1650"/> </AccessionNumber> </accessionObject> <owner> <Organization rdf:about = "http://www.amico.org/laf/entities/whitney_museum_of_american_art"> <name>Whitney Museum of American Art</name> <place>New York, New York, USA</place> <credit>Josephine N. Hopper Bequest</credit> </Organization> </owner> </Paintings> Obviously the class and property names (owner, Owner, ownerIdentity and Organization in the first example and accessionObject, AccessionNumber, organization and accessionNumber in the second) can be tweaked. Does anybody have a preference or any other suggestions? thanks, best regards Dr Mark H.
