[Person-ontology] Methodology using an upper ontology

[Schoening, James R Mr CIV USA AMC]

All,

It was posted (not sure by who):
	
	"Construct an ontology. It almost does not matter exactly where
you
	start, but either the very top (most general) or the very bottom
	(data) is not usually a good place."

Question: Why not use an existing upper ontology?  Wouldn't it provide a
good-enough top-down structure?  Wouldn't it also provide many (maybe
half) of the needed concepts? Of course, in parallel, gather
requirements and work from the bottom up.
