Exactly what I suggested to Svante you would do. I stated that you have a
need and you would spec out what your implementors would do. You are
deciding to do solve your need via rdf:types. What we provide is the
extensible mechanism (thanks to RDF) to do so. Now, Svante wants the
general solution to that problem (which I believe exists and its needed)
but I think we would be going outside our responsibility and scope. I
suggested to Svante that it is a separate spec built on top of ODF metadata
that he and KOffice and others can agree.

I think we have a really good and tight (yet general) specification. Any
more specific ontology classes and predicates will be looking for trouble
and decisions that we might wish left for a later time.
