This work is part of the Semantic Content Management sub-committee of the ebXML Registry TC [1] at OASIS. The goal is to provide support for publish, discovery and use of OWL ontologies and knowledge bases, and more generally RDF content, within an ebXML Registry. I would be interested in collaborating with others on this activity. Would it be possible for you to share your work-in-progress? -- Regards, Farrukh [1] http://www.oasis-open.org/committees/tc_home.php?wg_abbrev=regrep
