There's one hosted here:
	http://owl.cs.manchester.ac.uk/converter/

This is the one that would be hosted in W3C space. So it's not just  
for XML conversion.

Note that it's already being used by the test cases:
	http://www.w3.org/mid/200901211431.12300.mak@aifb.uni-karlsruhe.de
see the example:
	http://km.aifb.uni-karlsruhe.de/projects/owltests/index.php/Owl2-rl-rules
(Hmm. Gotta get the turtle in.)

I think we can make the interface a bit nicer there. I favor a tab view.

Note that this is the same code that drives Protege4.

The OWL API maintains all its historical parsers, so can consume OWL  
1, to OWL 1.1, to all the changes in OWL2.

OWL 1 can be parsed entirely (afaik) by a vanilla OWL 2 parser. So  
it's pretty peasy. A bit more fun woud be to have something that  
converted patterns to new syntactic sugar (e.g., lots of disjointWiths  
into an AllDisjoint).

Cheers,
Bijan.
