There is a new ISO draft document (stage 0) titled Geographic information -
Logical location identification scheme (ISO 19151) - that is moving through
the process in TC 211 (geomatics). I let the authors of this document know
of the work in the GeoPriv WG and the possibility that the two activities
are complementary but at this point perhaps also overlapping. Some snippets
from the document are below.
So, I suggested that perhaps the relevant parties get together for a one day
meeting at the late September OGC meetings in Darmstadt, Germany. If anyone
is interested, please let me know. I can also provide a draft of the 19151
document. As ISO has rather strict rules regarding such joint meetings, we
need to know whether we can schedule such a meeting at least by the end of
next week.
Also, if anyone from the IETF community wishes to attend the joint meeting,
the OGC will waive all registration fees.
Thanks and regards

1 Scope
This Standard proposes a logical position identification scheme, u-Position
to be used for referencing spatial information in any distributed
environments without physical position data such as coordinates.
This Standard specifies
. u-Position naming scheme and
. interfaces for operations to handle u-Positions.
1.1 U-Position URI
The u-Position is a logical and seamless expression of spatial reference in
the form of a label or a code that identifies a location. The naming scheme
of the u-Position(called u-Position URI) is defined based on URI syntax and
ABNF notation, as described in IETF RFC 3986(Uniform Resource Identifier
(URI) : Generic Syntax) and RFC2234(ABNF: the Augmented Backus-Naur Form).
The u-Position URI is used to indicate or access spatial information. The
u-Position URI syntax consists of a hierarchical sequence of four components
referred to as the scheme, host, port, and path_upos. The scheme, host,
path_upos are required, and the port is optional. 'path_upos' must begin
with a slash ("/").
u-Position URI = "upos" ":" "//" host [ ":" port ] path-upos
