I used the Protege editor some years back and due to my issues around requiring support for multiple inheritance in my Schemas, i decided to see where it hasd got to. Well, it has added full OWL support and some excellent tutorial papers.

So, when working with OWL, here is my suggestion.

1. Download Protege 3.2 with the full plugins.
2. Create a new OWL document using OWL/RDF Files
3. Use OWL DL
4. Install Pellet as the reasoner and run the DIG Server on port 8181

With this creating and reasoning with your Ontologys is really quite simple. In fact, structuring them properly is harder than using the tools - the tools are really quite excellent now.

The cool thing is that with the reasoning engine and Protege taxonomy option, you can get multilpe inheritance indirectly by defining based on a monotonic inheritance hierarchy, but using inference through the reasoner to build your hierarchy. Now I can start looking at building some of these things now!
