Re: Enhancing Data Interoperability with Ontologies, Canonical Forms, and Include Files

I must strongly object to these statements in your paper:
Ontologies can't State Relationships which Involve Transformations
Ontologies are not able to state relationships between entities that are
related via a transformation

The facts are:
Transformations are just special cases of actions.
Actions are just special cases of properties.
Any general purpose ontology must include actions!!!
