[georss] [OWS-4-SWE] Georss extension

Ron,

As I mentioned earlier, this is not an addressing scheme. This is a way to
support geolocation representation using different granularities
(zone/region/country/state...) to support areas as well as points earth-wide
and not just over land.
It would be great to have it fall under the GML umbrella so we could use a
custom profile to use it (like georss or geonames as a fallback).

Pat.

Carl:
 
This idea wa pursued in early GML 3 days base on the (I think) US postal
model. Idea was to have in effect a dictionary of postal address components
that could be expanded for localization but with positional or other forms
of equivalence.  Such a dictonary was created but there was no agreement on
this approach and we dropped it.

Ahh - gotcha. Perhaps, then, we need a simple xAL schema that then allows
the application developer the flexibility to use existing coding schemas
(ISO for country codes, SALB for administrative units, Flinn-Engdahl
zones/regions or any other designation as required. This would imply an
allowed list of region/zone taxonomies and perhaps something like a geo-mime
type. 

 

Cheers

 

Carl
