But if you want to get into treating fedora-model:hasModel as a sub-property of rdf:type, that's automatically OWL Full, if I remember right. IMO, the important first step is to get the basic object/datastream properties in machine readable form. > 3.

That would drag some datastream properties into the mix. I think having them all would be helpful.
