Hi Evan,

Thank you very much for your comments.

Yes, in the note [1] we provide a reference [2] to a first-order logic 
(FOL) axiomatization of the ontology, which includes a rich collection of 
axioms that tightly constrain the interpretation of the predicates and 
functions described in the note.

As the expressivity of the Semantic Web languages increase, depending 
on the logic they will support (e.g., full FOL or Horn logic), we would 
like to encode the entire or a subset of our FOL axiomatization of the 
ontology in the improved or new Semantic Web (rule) languages.

Please let us know if you have any further questions or comments.

Thanks!

- Feng Pan and Jerry Hobbs
