Re: [Geopriv] [VCARDDAV] The "geo" URI draft

Just to jump in:

There is a related ISO TC 211 activity similar to this proposal - but more
broad reaching (19151 - Geographic information - Logical position
identification scheme). They already have a level 0 document (first step on
the ISO standards track). I have to find out if I can share the draft
document. At a TC 211 meeting last week, I suggested they consider the work
of the GeoPRIV community. FYI, the submission team has working
implementations.

PS: From the document

1 u-position naming scheme(u-position URI)
The u-position is a logical and seamless spatial reference in the form of a
label or a code that identifies a location. 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
