Hi again friends, My apology Dan, I was, of course referring to your http://www.w3.org/2003/01/geo/ basic vocabulary and to the early related geoRSS adopted by Yahoo and others. re: > ... > Objectives > The Geospatial XG has three objectives which address needs of the Local Web: > * Immediate: update and harmonization with GeoRSS of the GEO vocabulary, aka simplest useful geospatial ontology. < ... Thanks Chris, for starting the discussion I expected this w3c working group would engage. Since many user communities are already entrenched using two alternate vocabularies, How can we agree on minimally simple mechanisms to reference and accept the alternate non native version of geoRSS ?

A constraint of this kind not directly expressable in OWL - so some of the rules are left unformalized. Still, I hope that what is present is correct. Comments welcome of course!

My own favored option would be to add geo:lat and geo:long to the set of properties that can asserted of a _Feature - endorsing this as an alternative to georss:point for expressing simple location. geo:latlong could be included as well (I don't really have an opinion on this one) I wouldn't include geo:Point nor geo:SpatialThing, because more semantic discord than harmony would be the likely result (also my bet is that these primitives have been less widely used than lat or long) Geo:alt should be excluded for a different reason: georss is 2d, so it doesn't really make sense to insert this as the only way of making an altitude statement - and one that is not applicable to lines, polygons, etc. > > That's only my opinion.

As (for SW Interest Group) editor of http://www.w3.org/2003/01/geo/ and the wgs84-based little RDF namespace there, am interested to hear of any proposed updates. What's the status of "neogeo"?
