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

Hi Folks,

Several weeks ago we had an excellent discussion on expressing the
relationship of entities that use different units-of-measure.  The more
general problem is - how do we express relationships that require a
transformation between the entities?

Based upon our discussions I have synthesized an approach to expressing
transformation relationships, and an approach that applications can take
to use this relationship information to enhance interoperability.  Here
is the URL to the paper I have written:
