Thanks John - this now works and loads into Protege. Great!

A couple of random comments from a first inspection:

- There are lots of individuals that seem to correspond to classes and  
object properties (and seem to be replaced by them, which sounds odd).  
Is this by intention?

- There is a class 'none'. Why? (It doesn't have a definition either.  
It seems to be used to indicate that some properties don't have a  
domain, but if that's true why not simply not provide a domain for  

- seeAlso often has the value 'not in ABCD', which is probably the  
wrong kind of value for this annotation.

- There are two classes with label 'Taxon' (but different URIs).  

- Same properties and some classes have the date suffix in their  
label. Intentional?

- Many classes and all object properties that aren't a subProperty  
have a date suffix in their identifier. Why, and if there is a good  
reason, why not all? Is term versioning the motivation? If so, are  
there so many updates expected that versions couldn't be handled by  
ontology releases (i.e., versioning through the ontology namespace,  
such as in http://purl.org/dc/elements/1.1).

The date suffix will become part of the element name in OWL instance  

	Ictalurus punctatus

Or am I missing something?
