Here is some stuff I found reading it - if you think I am off base or confused on any of this, well, you are probably right so phone me up and tell me the document is fine as is. A bunch of my comments are the same as when were at the EMS workshop.
I'm worried about the statement
It is RECOMMENDED that where uncertainty is included, a confidence of 95% is used.
Imagine that I have a 2d circle and 95% confidence is a radius of 100m and 99.9% confidence is 500m. For privacy reasons I might want to change the radius to 10,000m
I'd like to have the spec worded something more like the recommended is that the regions represent an area that 95% or greater confidence. I'm not sure exactly how to get these words correct but I think you see what I am getting at.
When you say
The edges of a polygon are defined by the shortest path between two points in space (not a geodesic curve).
You mean the points in real space on the earth? this is not really possible without the elevations. I think this needs a bit more clarity. I'll probably agree with whatever you put, It just is a bit vague.
Polygons SHOULD be defined with the upward normal pointing up.
I think this needs to be a MUST or don't bother with it at all a SHOULD will lead to bad bugs
Points specified in a polygon MUST be coplanar a
not exactly sure what this means in the geometries we are interested in
when discussing the GML point, please make it clear if implementation can treat these ad a ieee double or not. I'm basically get at the question about if 34.407 is the same as 34.407000 or not. I don't care about what the answer is, I care about having an RFC that clearly says it one way or the other so we can not argue about it.
#6, clarify what the reference north is for angles in arc band are (i.e. not magnetic)
(same for ellipsoid)
Allowing the prism to have a negative height makes it much harder to have a canonical representation for a prism. This makes it hard to compare and if we ever start signing stuff, harder to get things to canonical form for signing. Do you really want this flexibility? I'm OK with if you say yes, but please think about it. Some implementation will just get this wrong and I don't see what it buys.
Where it says
The shapes defined in [GeoShape] are the recommended shapes to ensure interoperability.
This needs to say the shapes defined in section 5 are the recommended shapes to ensure interoperability. And in
All above-listed shapes are mandatory to implementation
The above-listed shapes are MUST be implement.
where you have
it is recommended that Polygon shapes be restricted to a maximum of 15
this needs some normative language MUST or SHOULD
It's a style thing but the RAI documents mostly use the MUST/SHOULD style instead of RECOMMENDED / SHALL style. It would be better to be consistent on this.
I'm surprised there is not a circular prism shape as many devices end up with this. Trying to use a sphere is hard for some of these because the vertical accuracy is much better than the horizontal.
uh, not at all sure you should do this, but an example that showed how to take what came back from a DHCP response and turned it into some shape defined here would be really useful for implementors
This one is pretty irrelevant to the draft but given there are some IESG folks that care about URNs.
You have some examples like
This is sort of contriversial because no mac URN is defined (other than type 1 uuids). RFC 4478 does have mac:8asd7d7d70 but RFC 4480 has urn:x-mac:0003ba4811e3 as well as urn:device:0003ba4811e3 which is not an not an URN. By RFC 5025 we have
which is at least a valid URN. I'd recommend the last form of device-id.

The Presence Information Data Format Location Object
specification provides a flexible and versatile
means to represent
location information. There are, however,
circumstances that arise
when information needs to be constrained in how it
In these circumstances the range of options that
need to be
implemented are reduced. There is growing interest
in being able to
use location information contained in a PIDF-LO for
applications. To allow successful interoperability
applications, location information needs to be
normative and more
tightly constrained than is currently specified in
the RFC 4119
(PIDF-LO). This document makes recommendations on
how to constrain,
represent and interpret locations in a PIDF-LO. It
recommends a subset of GML that is mandatory to
applications involved in location based routing.
Working Group Summary
This document reflects a strong consensus of the
GEOPRIV working group.
The document was well reviewed within the working
group and received
comment from SIMPLE participants (specifically about
ensuring it took the
presence data model into consideration)
Robert Sparks is the Document Shepherd. Cullen Jennings
is the responsible AD.
The document has no IANA considerations.
