Are we not at risk of keeping the wiki beautiful, rather than digging into the nuts and bolts. 14:16:31 ggale: The email is a better medium for discussing things. Then maybe each week someone volunteers to clean up the topic areas. 14:16:39 cperey: I think that's fantastic and agree. 14:17:00 cperey: I just wanted a discussion framework. 14:17:04 ack nex 14:17:07 ack next 14:18:18 zakim, mute me 14:18:18 Matt should now be muted 14:18:29 matt: I was thinking the front page would be more like our home page. 14:18:46 matt: if there's lots of topics, I wouldn't want it to be obstructing the rest of the info on the page. 14:18:50 If the wiki gets more than 2 screenfuls on the home page then it needs tidying 14:19:03 cperey: Yeah, I don't like Resources as a name. And I liked upcoming events. 14:19:03 We're verging on that now 14:19:07 zakim, unmute me 14:19:07 Matt should no longer be muted 14:19:27 zakim, mute me 14:19:27 Matt should now be muted 14:19:31 cperey++ 14:19:44 matt: I think we all like it, let's move the discussion offline. 14:19:47 Topic: POI data format 14:20:01 andy: Temporal POI was the first sub topic. 14:20:12 andy: POI associated with refugee camps moving for instance. 14:20:20 +q 14:20:50 +q 14:21:05 q? 14:21:08 ack k 14:21:36 karl: Going back to ggale's definition of POI, if we can separate location from the definition... I think it'd be great for it to have a start and end. 14:21:43 "POIs have the shelf life of bananas" ... quote of the day so far 14:22:06 karl: Then there are temporal attributes of POIs. There's ones that exist at a time and cease, and another temporal aspect of "movies are from this time to this time", the theater doesn't end. 14:22:18 ack ggale 14:22:28 q+ 14:22:38 ggale: Aren't we in a chicken/egg situation. If we're trying to decide on a data format for something that we haven't decided on a definition of what it is. 14:23:04 ack mliebhold 14:23:12 mliebhold: I have a suggestion: it's easy to make things way more complex early on and then spend months digging out from premature complexity. It's either information about a place or a thing. 14:24:27 +q 14:24:27 mliebhold: I think for information about a place, there's only one characteristic that's critical: the degree of accuracy of the x,y,z coordinates. A POI could be an ornament on the build, which would need millimeter accuracy. For a thing, place isn't so relevant, and the only way I know how to do that is through a marker or trigger, a visual search, so a URI pointing to this. Everything else can be handled in RDF and triples handling any metadata they need. 14:24:29 ack ggale 14:24:55 ggale: I agree that we can make this arbitrarily complex then spend months digging ourselves out of the hole. 14:25:07 +q 14:25:16 ggale: Maybe I can ask if we're happy with the three tier model I put on the wiki, and if so, have others flesh each out on the wiki. 14:25:40 ggale: Then let's see if we can use existing codifications/standards. 14:25:48 ggale: See if we can merge them back into a single entity. 14:25:55 ggale: Then check the use cases, see if we can cover those. 14:26:03 karl: I haven't had a chance to look at the wiki yet. 14:26:49 karl: I'm working on the terminology page. Then we'll try to make the vocabulary consistent. This goes back to defining a model that's grounded in existing standards and definitions. If you think I'm introducing complexity let me know. 14:26:52 ack jdesmit 14:27:06 jdesmit: I like your approach, and I like Mike's comment about a 'thing'. 14:27:29 jdesmit: ?? place definition on the wiki ?? 14:27:46 karl: Let's write up the place definition on the mailing list and get people to make edits on the wiki. 14:27:48 good proposal 14:28:09 ??: Have three or four people drive the definition down. 14:28:21 ggale: I'd rather have the debate on the mailing list. 14:28:23 matt that last was Karl S 14:28:26 ggale: rather than the wiki 14:28:26 +1 14:28:31 s/??/Karl/ 14:28:33 +1 on mail over wiki 14:28:34 +1!! 14:28:38 q? 14:28:42 zakim, who is noisy? 14:28:53 matt, listening for 10 seconds I heard sound from the following: Andy (24%), +1.347.661.aajj (14%) 14:28:53 zakim, unmute me 14:28:56 Matt should no longer be muted 14:29:01 so what is the w3c method to form work teams 14:29:10 zakim, mute me 14:29:10 Matt should now be muted 14:29:30 thing (cute name) 14:29:44 an object? 14:29:46 zakim, unmute me 14:29:46 Matt should no longer be muted 14:29:57 zakim, mute me 14:29:57 Matt should now be muted 14:29:59 i volunteer to be on the POI detailed definition work team 14:30:07 ACTION: mliebhold to put out a definition of a 'thing' to the mailing list. 14:30:07 Created ACTION-13 - Put out a definition of a 'thing' to the mailing list.

How do we see this information model being used? Are services harvesting around the internet and then we do our own queries or...? 14:33:07 lost him? 14:33:15 zakim, unmute me 14:33:15 Matt should no longer be muted 14:33:28 -Raj 14:33:31 zakim, mute me 14:33:31 Matt should now be muted 14:34:00 ggale: Sounds like the question Raj was asking was: are we defining the reference model or defining the services that expose the reference model? Or are we building the reference model. 14:34:20 karl: I think the root of it all, the value, is for information exchange between systems. 14:34:24 karl: That is fundamental. 14:34:53 +1 looking for a data exchange model 14:35:10 ggale: I see us looking at how this is exchange rather than building stuff. 14:35:22 agreed. services are what we use eventually, but I think data exchange format should be the focus 14:35:51 +q 14:35:52 + +1.617.642.aall 14:35:53 andy: We don't want to be in the business of building services. We're looking at building something that exists today. What use cases do we need to satisfy? But I don't think we need to be in the business of defining how the sevices work. 14:35:54 +1 14:35:57 ack ahill2 14:36:05 services development are how companies differentiate themselves 14:36:42 q+ 14:36:42 ahill2: Those of you with more experience building services around data models, can anyone comment on, if what we want to do is build a data exchange model, is there advice on what to look out for? Or can we just ignore services when we're constructing a data model? 14:36:49 zakim, aaii is rsingh2 14:36:49 sorry, matt, I do not recognize a party named 'aaii' 14:37:18 Carl: If we wrap ourselves around the services that make the data model sing, we'll be wrapped around the axel. 14:37:24 ahill2: That sounds like a reasonable suggestion. 14:37:27 q? 14:37:29 +1 14:37:31 ack ahill2 14:37:41 zakim, unmute me 14:37:41 Matt should no longer be muted 14:37:44 zakim, mute me 14:37:44 Matt should now be muted 14:37:51 Karl seiler will intro himself as "seiler" 14:38:07 jacques: Services will be useful to test the data model, but ??noise?? 14:38:11 zakim, unmute me 14:38:11 Matt should no longer be muted 14:38:20 zakim, mute me 14:38:20 Matt should now be muted 14:38:24 -Andy 14:38:54 jacques: I want to make a list of triples in XML or RDF that could be useful, they're on the mailing list. 14:38:58 +1 for jacques action item 14:39:01 zakim, unmute me 14:39:01 Matt should no longer be muted 14:39:20 jacques volunteered Action Item to write up some triples according to suggestion on the mialing list 14:39:27 ok 14:39:38 ACTION: jacques to collect triples on the mailing list 14:39:38 Created ACTION-14 - Collect triples on the mailing list [on Jacques Lemordant - due 2010-11-17]. 14:40:04 Carl: It's a worthy effort, perhaps cart before the horse. There's a lot of standards in this area. 14:40:10 a new thread in discussion framework 14:41:29 http://www.w3.org/2010/POI/wiki/Related_Specifications 14:41:44 +q 14:41:49 ack ahill2 14:41:52 ack ahill2 14:41:53 ack jacques 14:42:18 ahill2: As we're fleshing this out, could we have examples 14:42:19 +1 14:42:22 seiler - good idea 14:42:23 +1 14:42:41 +1 to Alex suggestion to have examples 14:43:04 Carl: Seems to me that until we have a data model or agreed definition of POI, then evaluating specific encodings is premature. 14:43:04 +1 to examples 14:43:23 matt: Maybe we do this after we have data model and use cases in place. 14:43:35 ahill2: When it does happen, I'd vote for having things inline, rather than separated out. 14:43:48 ahill2: There's a tendency to have definitions that lead other places. 14:44:10 jdesmit: As we try to agree or converge on a data model then let's introduce examples. 14:44:39 ahill2: What we really want to do is hash out the data model first and get ourselves happy with that before we move on. 14:44:57 Karl: Isn't the data model work bounded by the definitions work? 14:45:15 ahill2: I maybe meant definitions. Definition of POI and the four tiers that have been mentioned. 14:45:23 ahill2: The three original ones and 'thing' that has been suggested. 14:45:43 +1 on the discussion of order of focus but, isn't this going to be an iterative process? 14:46:14 matt: So, we'll work on definition of POI, data model, then use cases, then standards. 14:46:35 rsingh2: I'd like to make a radical proposal that a POI is just a location and time. We're not going to be able to agree on the other things for now. 14:47:07 rsingh2: I can see people having databases of a few thousand POIs in these use cases. And then most of the sophisticated stuff could be done in the client. 14:47:22 rsingh2: A definition that has more than location, geography and a start and end time is going to have us going in circles. 14:47:36 Carl: I just added a third definition of POI that the IETF uses. 14:47:59 Carl: So, it comes down to location and time, everything else are optional properties. 14:48:02 zakim,unmute me 14:48:02 Matt was not muted, matt 14:48:07 +Q 14:48:20 -Mike_Liebhold 14:48:22 -q 14:48:25 zakim, mute me 14:48:25 Matt should now be muted 14:48:26 location, time and content 14:48:41 zakim,unmute me 14:48:41 Matt should no longer be muted 14:48:44 q? 14:48:55 I'm going to drop off, will dial back in 14:49:04 -cperey 14:49:12 +q 14:49:26 zakim, mute me 14:49:26 Matt should now be muted 14:49:30 +Mike_Liebhold 14:49:42 ahill2: When we say UUID, are we talking about the location, or the event? 14:49:48 ahill2: Is it the place or the location? 14:50:15 karl: I think it's a POI. I think the definition of places, which are often bounded by polygons, can be prescriptively defined. There's a lot of standards we can comply with or meld. 14:50:21 karl: Same thing with addresses. 14:50:24 zakim, unmute me 14:50:24 Matt should no longer be muted 14:51:42 karl: I think we can define location, there's a lot of definitions for that, places, polygon structures, then... our definition of POI should be simple, very open ended. I like the IETF definition. 14:51:44 +q 14:51:52 ack next 14:51:52 -q 14:52:28 mliebhold: I sent mail, we can start with them associated only with location, but you can frankly have a POI attached to a physical object. We might postpone that discussion, but we'll have to get to it. 14:52:28 +1 to mike 14:52:37 +1 4 dimensions + POI 14:52:42 -Carl 14:53:04 Topic: Use Cases 14:53:05 http://www.w3.org/2010/POI/wiki/Use_Cases 14:53:59 +Q 14:54:08 ahill2: Whenever the subject of visual recognition and temporal moving objects comes up, I would make the initial suggest that I'm not sure the data model needs to necessarily... location can be transient... moving objects, or things, be folded into location, so that we don't have to keep track of whether something is a moving object or distinguish it from a fixed place 14:54:09 + for tracker information in the data model 14:54:09 ack next 14:54:39 mliebhold: That would require every object to disclose it's location. That's probably a burden that isn't appropriate for everything. A POI as a loaf of bread. 14:54:47 ahill2: I think we should take this to email.' 14:55:36 rsingh2: I don't think it's an edge case. There's things like lunch trucks that serve every day or hour serving different people. 14:55:50 ahill2: Not an edge case necessarily, but from a practical standpoint how to fold it into the definition. 14:56:07 -q 14:56:29 +cperey 14:56:47 I need to sign off ... next meeting in the day job calls 14:56:59 matt: On use cases, any volunteers for this?
