    I concur with that.

    It will be interesting to see how that will work in DAML or OWL.
    The same ontology could have a function to give the default center 
    point or address of a city in order to handle situations where a 
    point-based representation is desired.
    Probably a collection of functions:  Municipal center, centroid, etc.
