I think we should just state the location is the information necessary to place the POI in the world....whatever that information is. I don't think it should be empty, but it should be possible to state position in a number of ways. Location (at least one of; lat/long/alt OR a referance to another POI+x/y/z displacement from it OR a RFID string to identify a signal OR a image to match again + possible x/y/z displacement from it OR ..... ) The requirement of the location value shouldn't stop there being many possibilies within it. I dont think we need to define all the possibilties now either. ~~~~~~ Reviews of anything, by anyone; www.rateoholic.co.uk Please try out my new site and give feedback :) On 27 April 2011 06:19, 전종홍 <hollobit@etri.re.kr> wrote: > I think we should consider both. > > So, I think that Location is only the one of optional information. > > Best Regards, > > --- Jonathan Jeon > >> -----Original Message----- >> From: public-poiwg-request@w3.org [mailto:public-poiwg-request@w3.org] On >> Behalf Of Seiler, Karl >> Sent: Wednesday, April 27, 2011 6:32 AM >> To: nathan@webr3.org; Andy Braun >> Cc: Roy Davies; Thomas Wrobel; Hegde, Vinod; public-poiwg@w3.org; Dan >> Brickley >> Subject: RE: Categorization + Whether a POI must have location >> >> I am beginning to feel like this is a recurring and circular discussion. >> Things (people, staplers, cars) have highly variable locations and places >> (a park, buildings, a store, a photo spot, a scenic drive) also have low >> volatility locations. >> >> Are we encompassing both or just places. >> >> _______________________________ >> Karl Seiler >> Director Location Technology & Services >> NAVTEQ - Chicago >> (T) +312-894-7231 >> (M) +312-375-5932 >> www.navteq.com >> >> -----Original Message----- >> From: Nathan [mailto:nathan@webr3.org] >> Sent: Tuesday, April 26, 2011 4:25 PM >> To: Andy Braun >> Cc: Roy Davies; Seiler, Karl; Thomas Wrobel; Hegde, Vinod; public- >> poiwg@w3.org; Dan Brickley >> Subject: Re: Categorization + Whether a POI must have location >> >> Overlaying the current location of a train/bus on a map or augmented on a >> street view?
