Hello,

To which document are you referring here: the structural specification (http://www.w3.org/2007/OWL/wiki/Syntax) or the UML metamodel
(http://www.w3.org/2007/OWL/wiki/MOF-Based_Metamodel)?

I believe that the UML metamodel document is the proper document to align OWL 1.1 with OMG ODM.

In contrast, I don't think that this should be reflected in the structural specification document. There, we used UML just as a
simple light-weight mechanism for specifying an object model. The main reason for having the object-model based specification was to
ease the life for developers. I have had some positive feedback from the implementers of the new OWL API on this -- they turned this
object model more of less directly into interfaces of the API. Thus, I believe it is important to keep this object model simple, and
I don't consider alignment with OMG ODM in this document appropriate.

If the name "UML" poses problems as such, we can simply remove all references to UML from the structural specification document and
simply call it an "object model".

Regards,

	Boris
