Tom, Thanks for the reply; I really appreciate it. > I do not think that you should model theCommittee as a bag. > It would be better as the instance of some class (like > Committee), with a property, say, Membership.

These questions have suddenly > become moot - at least, they no longer arise for this example. So a possible XML serialization would be: <r:Description r:about="theCommitte" r:type="http://www.foo.com#Committee"> <ex:treasurer rdf:resource="http://www.bar.com#Jim" /> <ex:membership> <r:Bag> <r:li r:resource="http://www.bar.com#Jim" /> <r:li r:resource="http://www.bar.com#John" /> <r:li r:resource="http://www.bar.com#Jane" /> <r:li r:resource="http://www.bar.com#Jamie" /> </r:Bag> </ex:membership> </r:Description> Correct? And the Bag represents an unordered set (in the mathematical sense) of resource? What would be the difference between that and the following: <r:Description r:about="theCommitte" r:type="http://www.foo.com#Committee"> <ex:treasurer rdf:resource="http://www.bar.com#Jim" /> <ex:membership r:resource="http://www.bar.com#Jim" /> <ex:membership r:resource="http://www.bar.com#John" /> <ex:membership r:resource="http://www.bar.com#Jane" /> <ex:membership r:resource="http://www.bar.com#Jamie" /> </r:Description> Does that mean the same thing? How is the meaning different? And how is that different from: <r:Description r:about="theCommitte" r:type="http://www.foo.com#Committee"> <ex:treasurer rdf:resource="http://www.bar.com#Jim" /> <ex:membership r:parseType="Collection"> <r:type r:resource="http://www.w3.org/1999/02/22-rdf-syntax-ns#Bag" /> <r:li r:resource="http://www.bar.com#Jim" /> <r:li r:resource="http://www.bar.com#John" /> <r:li r:resource="http://www.bar.com#Jane" /> <r:li r:resource="http://www.bar.com#Jamie" /> </ex:membership> </r:Description> I'm a bit confused about the semantics of each of the container representations in RDF. -- Jimmy Cerra ] "My mind is slipping away... ] day by glorious day." - RAG III
