And if one wants to autoconvert UML to OWL there is this tool at

      UMLtoOWL: Converter from UML to OWL

 


      General information

The UMLtoOWL tool converts extended Ontology UML Profile (OUP) models in 
XML Metadata Interchange (XMI) format to The Web Ontology Language (OWL) 
<http://www.w3.org/TR/2004/REC-owl-ref-20040210> ontologies. The tool is 
implemented by using eXtensible Stylesheet Language Transformation 
(XSLT). With UMLtoOWL we do not need to modify the existing UML tools. A 
UML tool can export an XMI document that an XSLT processor (e.g. Xalan 
Java 2 <http://xml.apache.org/xalan-j/index.html>) can use as input. An 
OWL document is produced as the output, and this format can be imported 
into a tool specialized for ontology development (e.g. Protégé 
<http://protege.stanford.edu/>) where it can be further refined.

This work is a part of the Good Old AI <http://goodoldai.org.yu/> 
research effort to develop an MDA based ontology infrastructure 
<http://www.comsis.fon.bg.ac.yu/ComSISpdf/Volume01/Papers/DraganDjuric.pdf>.
