Aren't there refactoring tools integrated into ontology editors?

Yes, datatype properties are not supported, it's work in progress.
I'm not sure how constrained the set of cases without datatype properties
is. Some large ontologies (Galen?) don't use them at all.

That would be an easy change, but I think the round-trip requirement
is really important. It enables the "view source" effect, i.e. one can view
the OWL file in ACE, do some modifications (in ACE) and publish it
again (in OWL).
Knowing the details of ACE wouldn't be needed in many cases.

OK, but would you consider using verbs for properties in your next ontology
(that you have full control over)? :)
