Al (et):

I concur with the vision statement.
Personally I believe that this work should (obviously) leverage the
valuable insights gained through Thesaurus management , and the Metadata
managment knowledge generated by the OASIS ebXMLRegistry (& Repository)
Semantic Content SC and the Business Centric Methodology TC (which
leverages a Semantic Layer that my be populated with  controlled
vocabularies, thesauri, OWL ontologies etc). AND that this SKOS Core work
will be referenced by many OASIS TCs.
