Brian, Sorry, but the approach described in the MT document currently up on the W3C site does *not* address the layering problem. It does with a change which introduces a small wording modification (but only the wording modification is small). As per W3C processes, we could rule the layering problem out of scope, etc. and quickly move to completion. But if RDF aspires to be a basis for OWL and other languages, it has to solve the layering problem. If it does not, OWL and others will be forced to introduce constructs which make RDF and them non-monotonic, etc. The current layering issue is focussed on being able to build pyramids of model theories. The problem of layering is broader and significant. A melange of model theories does little to ensure machine interoperability. A solution to this problem is what makes these two drafts interesting. guha Brian McBride wrote: > > > > The primary motivation for this work is addressing the layering > problem.
