[Geopriv] Some comments on draft-thomson-geopriv-uncertainty-08

[Brian Rosen <[e-mail]>]

I’ve read this draft, and think it is an excellent explanation of the
issues we face in geopriv with measurements.  I highly recommend that we
adopt the draft and process it as a work group item.  I am particularly
happy with the definitions it offers for the various quantities.


I find it lacking in two areas:


1. I think the draft needs to discuss the issues of comparing measurements
with different confidence.  I think the bottom line on that is: don’t do
it, use one agreed upon confidence.

2. I think we need to stop expressing measurements as just the uncertainty
area.  While I understand why doing so is attractive, I think it is not
what real systems do.  Real systems express a measurement and explicitly
state the uncertainty of the measurement.  I think we need a way to express
that.
