I am starting to work with OWL using Protégé. It is all very intuitive for someone with a background on ontologies. With the onotology specified I would need to implement it as a relational schema in a DBMS. I have so far found references to two tools, none of which are usable in my case:
An old plug-in for Protégé exists, but can only deal with mySQL.
A article from the International Journal of Advanced Computer Science and Applications refers to a tool named OWLMap, but it is nowhere to be found (I wonder how this article was reviewed).
It is not difficult to use a OWL library to load a model into an OO language and then derive a relational schema from it. But if a tool or method already exists I would rather avoid developing something new.
