By direct support I meant evolution of RIM to layer on top of RDF and 
OWL allowing RIM defined metadata to be more extensible and semantically 
expressive. RIM ClassificationSchemes could evolve into OWL ontologies 
which could be used for classifying objects.

As for DAML-S, as you correctly observed, a mapping of DAML-S to ebXML 
Registry can be easily done based upon current version of the specs and 
could be added as a Technical Note.

However, with the "direct support" of RDF and OWL the mapping could take 
closer advanatage of the new RDF enabled type/attribute extensibility 
and OWL based ontology/classification support in RIM.
