RE: general question

The charter states we don't worry about that.
The answer is, there are quite a few methods,
any of which will work:

1. GPS
2. Triangulation of a radio transmitter
3. Dead reckoning
4. Others too numerous to mention

A combination may often be used.

Interestingly, there are plenty of uses where
the thing we want to find the location of doesn't
actually move. The one of interest to me is
a telephone. Most phones don't move. An office
phone "might" move, but the socket it is plugged
to in the wall doesn't (don't mean to imply
"EVER" here). I want the geopriv object to
work in that case -- the location might be
manually entered in such a case.

Of course, we get to an old issue with reporting
location - in what form? Many times, people
assume that it's lat/lon/altitude, but often
we want country/state/county/city/street/building/
floor/room. You can translate from one to the other
with a database.

What does this mean to geopriv?

 - the object has to work with a wide variety of
location determination mechanisms, including
manually entered.

 - the object has to work with stationary objects

 - The object has to support both ways of representing
location simultaneously (that is, both representations
may be in a single report)

 - There has to be a way to support a translator as an
independent entity in the path from producer to
consumer.

 - The object has to have some flags that tell you what
the original format was, and identifier of
who translated it.
