In the utility domain UML has been pretty extensively used for defining
abstact schema which are then converted to RDF schema.  I maintain some web
pages with links about this [1,2].  There are various standards bodies and
discussion groups involved.

We convert these UML models to (extended) RDF schema using a tool [3].
Unfortunately, the full detail of the UML/RDFS mapping is not documented
properly yet.  But the main points are to be found in a related OMG
specification [4] (section 8.2).

I personally don't find UML as flexible as an RDF-based ontology. I would
suggest that the basic problem is that UML makes classes first class
citizens but not properties (associations/attributes). However, it is well
accepted and has a graphical representation that people like.
