Hi Mark,

I agree with your assessment that ebXML Registry version 2.5 currently 
provides generic Content Management (CM) support but does not yet 
provide first class support for Semantic Content Management (SCM) based 
upon RDF and OWL.

Above are very insightful and thought provoking questions.

The ebXML Registry standard has plans to align with the W3C Semantic Web 
Activity (SWA) in version 4 with first class support for managing RDF 
and OWL content. In version 3, CM was our focus. In version 4, SCM will 
be the focus.

We intend to make ebXML Registry a "Semantic Web Server" in future. We 
hope that in this future vision, ebXML Registry will be to the Semantic 
Web what Web Servers are to the Web today.

In a recent conversation with Eric Miller of SWA I was pleasantly 
surprised at the close alignment in our vision of the future and the 
role of ebXML Registry in the Semantic Web. In fact it was on Eric's 
suggestion that I joined this list to learn more about SIMILE and 
explore potential for collaboration between SIMILE and ebXML Registry.

IMO, The ebxmlrr project being open source allows a collaborative effort 
to enhance it further to support RDF and OWL ahead of the standard. The 
current ebxmlrr functionality provides a decent functional subtsrate 
upon which to build support for SCM based upon RDF and OWL.

I hope this collaboration potential is as interesting to the SIMILE 
folks as it is to the ebXML Registry folks. If so we should engage in 
further exploration of the idea.
