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://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,
"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:
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?
