The open source ebXML Registry and Repository project [1] at SourceForge 
is planning
to support ontologies in its next version. The current version is 
capable of managing
arbitrary content (e.g. OWL ontologies) and standarized metadata.

Curently its supports simple hierarchical taxonomies and has concrete 
plans for implementing
support for OWL ontologies.

If any one is interested in contributing to that work please contact me 
directly. Thanks.
