reports your longitude, lattitude, velocity, city and/or country using gps, ip address mapping, cell tower triangulation or other means. > - why is it a Gnome project? because some GNOMiEs started it. it has minimal dependencies at this point, though. > Shouldn't we be getting > this kind of data from a SPARQL endpoint out on the web somewhere? I did once we know the physical location of the device, sure. but until then ... what good would a SPARQL query be? and that's the part that geoclue fills in. the downsides of geoclue are, imho: * there are exactly zero packages for things that aren't maemo * there is nearly zero documentation online for how to use the damn thing * it's written in C, but that's more a personal preference than anything i suppose ;) the upsides of geoclue are, imho: * it exists and works (both on my laptop and on my N810) * there are no other F/OSS equivalents out there that i know of * the geoclue people are excited to work with us, and the lead dev attended Akademy and presented on it all the actual location<->context/data mapping will, of course, happen within nepomuk itself. geoclue is just there to answer "where am i", everything else happens in more sane locations. -- Aaron J.
