Re: Proposal:GeoJSON

Hi, Strainu.

I wonder whether the approach you are proposing can be generalised for
other types of encoding / representation of geometries (WKT, GML, KML, RDF,
or even human readable documents).

BTW, this could allow re-use of "geometry URIs" (as those operated by
Placetime.com [1] and Ordnance Survey), i.e., URIs identifying geometries
and resolving to different geometry encodings / representations, following
Linked Data principles.

As an example, see:

http://data.ordnancesurvey.co.uk/id/geometry/37256-10

which resolves to

http://data.ordnancesurvey.co.uk/doc/geometry/37256-10

The different supported representations have also specific URIs:

http://data.ordnancesurvey.co.uk/doc/geometry/37256-10.html
http://data.ordnancesurvey.co.uk/doc/geometry/37256-10.rdf
http://data.ordnancesurvey.co.uk/doc/geometry/37256-10.ttl
http://data.ordnancesurvey.co.uk/doc/geometry/37256-10.json
