If you'll send me a small example UML model in Poseidon UML or ArgUML and
tell me what RDFS/XSD should result, I'll implement that, add that beginning
XSLT implementation to exff.sourceforge.net and make anyone interested in
helping a developer on that project. If there's a more appropriate
open-source project, 

All my work so far has been to generate OWL but RDFS support sounds like a
good idea too. FYI, the draft OMG ODM standard includes a metamodel for RDFS
and UML and will include a mapping so there will be a standard to implement
at some point next year. The next draft from the ODM team is due in January.
The current draft does not include any mappings.

All my work is XMI-based as it's written as XSLT. This architecture was
chosen because several tools provide XMI export but no API. FYI, I have also
used the Poseidon PE Velocity Template engine to generate XML Schema from
UML and from that you access to its API.

I have done some work with ArgoUML so understand its XMI format. Most of
what's there now works with Poseidon UML Community Edition.
