we'd like to offer some positive reasons for optionally allowing the
RDFIG namespace for geo:Points with latitude and longitude referenced to
the wgs84 datum;


- the WGS84 datum is assumed in the schema so there's no need to send a
datum attribute with each point.
- having lat and long as separate properties arguably makes parsing and
validation easier
- it is trivially extensible with properties from other RDF vocabularies shows a guideline for a simple
'geoannotation' object which uses the FOAF vocabulary[0] to make
assertions about the person or other presentity who annotated that point
in space and time, and the media optionally attached to it. shows a
simple rdf/xml -> GML converter for those who really want GML. This was
done at a collaborative mapping workshop at the Emerging Tech conf last
week, at which some of us saw Jon Peterson's talk about geopriv and
presence work, which led us here. thanks.
