The relationship between RDF and DAML+OIL has been unfairly characteristed.

In any case we ought to be looking at the relationship between RDF and OWL
at this stage in the game. The relationship between the two formal semantics
is a technical tour de force (IMHO) whose clarification has been a year or
more in development. See: http://www.w3.org/TR/owl-semantics/ for rather
precise details. I'm sure you'll agree that OWL has quite its own
contribution to the collective semantics.
