Ronald and Pat,    (01)

There is no such thing as a single, ideal ontology that captures
every useful way of looking at everything from every possible
perspective and granularity for every purpose.    (02)

There are many different theories of contexts, situations,
and situated communicating and interacting agents.  Those
systems, theories, and implementations are valuable and
efficient for many kinds of purposes.  In fact, they reflect
the way people happen to be situated in some finite chunk
of reality from one moment to the next.    (03)

But other representations are useful for different applications,
and there are systematic ways of converting one to the other.
In particular, it's important to communicate with situated agents
in terms of the situation in which they are operating.    (04)

When an accident is imminent, you don't want to send a driver
(or the car) a fully-qualified 4D specification.  You just want
to say "STOP!"    (05)

Fundamental principle:  Any single uniform universal representation
is guaranteed to be awkward, inconvenient, or inefficient for a huge
number of critical applications.    (06)
