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.

Hi Team,

I've been looking at the sample Amico data and there is a problem with the
way that owner is encoded

<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>
    <place>New York, New York, USA</place>
    <credit>Josephine N. 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
