For me it doesn't matter if the Ontology is complex or not as long as the API is simple. But it is of course an advantage if the Ontology is also light weight as long as it can cope with requirement r07: "Introducing several abstraction levels in the ontology". Maybe "dc:source" is enough!

   I agree whole-heartedly - the first version of this spec should  
take as minimalistic an approach as possible.

   I believe a single abstraction layer will be quite powerful, and  
additional complexity can be built on top of this in the next version  
of the spec *if* it proves to be necessary as people use the first  
version of the API.
