Generating UML from the ontology

Is there a way to generate a UML diagram. Essentially, I used an SQL ORM lately and having the capability of generating a UML diagram of reality was really great. That got me thinking this would be a great feature if Stardog Studio or other would support this.

Depending on your ontology (ignore me if you know this already, and yours will be fine), a mapping to UML won't typically be feasible in a useful way. If you have Sparx Enterprise Architect available to you (I think they have a 30 day trial), you can load an RDF file into that and it will generate UML as best it can.


Is there any MacOS software that can be used to convert an ontology to UML ?
