Hello Chris,

while I agree it is disputable whether there is something geo specific to
the naming of geo-referenced entities, it should not be overlooked that
there are several areas where there is a need for a standardized geo
vocabulary, namely (to name a few):
 - topological relationships
 - geometry descriptions
 - coordinate systems
 - ... (everyone please complete the list)

Besides, one of the purposes of this group (in my understanding) is not to
reinvent the wheel, but choose among the many wheels already existing and
come to an agreement on the most suitable one in a geo context. Or bridge
them.

my 2c,

--p.
