[Person-ontology] Upper and middle ontology for interoperability purposes

[Schoening, James R Mr CIV USA AMC]

Pat,

	I agree that when building a stand-alone ontology, an upper
ontology isn't needed and is costly to use.

	But Higgins needs interoperability in various respects.
Extensions will be developed in finance, education, medicine, home
maintenance, and other areas where people want to store and share data.
People will want to interface with vendors, governments, and other
people.  Wouldn't the use of an upper ontology (OK, add a middle
ontology for common concepts) help with consistent interoperability
across these domains and sharing partner?
