Here's a simple OWL question, that all of these tools seem to answer in 
a different way: What is the connection between the physical URI of an 
ontology definition document and the logical URI that is used for the 
owl:Classes defined in that document?

Here are some possible answers for what the logical URI is:

1) It's the same as the physical URI.

2) It's the default namespace of the definition document (the 
xmlns="namespace").

3) It's the value of the rdf:about attribute of the owl:Ontology element.

4) It's not even in the document, but has to be supplied by a 
"LogicalURIResolver", which somehow has access to a database of 
logical/physical mappings.

5) None of the above, so you had better hard code it in the definition 
of  every single class.

The published OWL Guide/Reference appear to me to be using (2), but 
nothing explicitly says that that's how it should be. Any guidance?

Thanks,

Jeff
