I'll not explore the concept of a university too far, since very
little about groups of people is relevant to OSM!

However, if you were to say "What is the physical aspect of a
university" then I would say it's a collection of one or more places -
usually parcels of ground, often with buildings. In OpenStreetMap we
tend to represent collections of entities with a relation, unless the
tagging of each part is substantially the same (i.e. no need for a
relation when you split a road and add bridge tags.

I note that the amenity=university tag is used mostly (exclusively?)
on buildings, and I think that this is incorrect. I would expect a way
tagged amenity=university to indicate that everything within that way
- buildings, gardens, carparks etc - was part of the university. So we
can probably retag things to cut down the numbers by using perimeters
around particular areas.

Yep, I certainly agree with you there. But when things are tagged
'incorrectly' (fsvo incorrect, of course), then we need to change the
tagging.

Yep, I've gone on at length about this with people wishing to change
the order of the characters within a particular tag - it's
infuriating.

Be careful. To say that we need to support your old tagging scheme
indefinitely would seem to be a slap in the face for all our
volunteers, now and in the future.

Thanks,
