[rdfweb-dev] updated geoonion vocab - feedback welcomed

[Dan Brickley]

As some of you know, we have a little geo vocab in a w3c 
namespace, not standards-track but just to help move things along...
it has lat/long/alt properties and classes for Point and SpatialThing, 
ie. very minimalistic. 
http://esw.w3.org/topic/GeoInfo and
http://www.w3.org/2003/01/geo/ have details.

I'm interested in finding similar minimalistic conventions for hooking
descriptions of points up to more socially interesting things, and 
have on and off been playing with a vocab for this, in discussion w/ 
zool, damian and others.

http://esw.w3.org/topic/GeoOnion has what little detail there is. I have
today updated the draft in the wiki, with a couple of sample scales 
(powers of 5, and of 3, with metres as the unit).

I'm looking for a bit of sanity checking on this, then maybe its time 
to create a namespace and schema for it.

The FOAF connection: it should come in handy for stuff like photo 
annotation, describing in more detail where things are (either in
realtime, per http://rdfweb.org/topic/FoafMobile) or as an elaboration of
the http://xmlns.com/foaf/0.1/#term_based_near concept. It should be 
useful for describing local small businesses and 'postcard in 
shop window' buy/sell apps. The trick is to pick the right scale, units
etc so the circles are usefully space.

I'd also love an SVG visualization of this. "Show me restaurants within
5^5 metres from <here>" etc., again with the mobile/gps use cases...

Following up the Foodie use case, more notes and data (Grubstreet,
ChefMoz etc) on that can also be found in the ESW wiki, 
http://esw.w3.org/topic/RestaurantRecommendation

"play me audio reviews of restaurants within 5^4 metres that serve 
vegetarian food, where the reviewer was vegetarian..."

previous notes on related use case:

	http://rdfweb.org/pipermail/rdfweb-dev/2002-December/001408.html
	foaf use case: vegetarian / airline bookings

	and prev vocab for that bit: http://www.cs.umd.edu/~golbeck/daml/vegetarian.daml


people, places, food, mobile phones, gps, audio/multimedia,
annotations... did I mention lately that everything's connected?
