your OOobject is your RDFsubject, your OOobject property is your RDFpredicate, and your OOobject property's value(s) is/are your RDFobject(s) (mind the nameclash)

your OOobject have URI fields, of course.

this also works with JSON.. which can be thought of as an OOobject serialization, and compatible with RDF so long as your property-symbols are URIs and each JSONobject has a URI property

theyre pretty much identical. even RDFs with its subclassing and subtyping is an OO model.. replace 'object' with 'resource' in the literature
