Topic: Use Case Review
13:42:37 [matt]
-> http://www.w3.org/2010/POI/wiki/Core_Scope Scope chart
13:42:43 [Ronald]
Alex: is a search for rich content (entrance fee) part of POI or is it a web search
13:43:46 [Ronald]
gary: rich content out of scope
13:44:20 [Ronald]
gary: only add it as extensible, but don't make it part of the POI core. Principle 10
13:44:38 [Ronald]
Alex: how is rich data facilitated
13:45:10 [Ronald]
gary: extension mechanism. it is up to the content provider
13:45:56 [Ronald]
gary: let's go over all use cases and see what's in scope and what is out
13:46:36 [Ronald]
gary: getting really rich content is a specialised effort with high cost
13:47:23 [Ronald]
alex__: all search use cases are out of scope
13:48:22 [Ronald]
gary: historical pricing information is not part of the spec, but extension supports it
13:49:06 [andy]
andy has joined #poiwg
13:50:00 [Ronald]
matt: we should look at one or two use cases and describe how it would be done
13:50:32 [Ronald]
alex__: thinks it is a useful exercise, but not for the F2F
13:50:57 [Ronald]
andy: concerned on why to adopt the standard
13:51:14 [Ronald]
gary: standard does not enforce the business model
13:51:30 [Ronald]
karl: standard helps in aggregating data
13:52:23 [Ronald]
alex__: in an AR browser like Layar will benifit from a standard

karl: categorization will be proprietary, but knowing what field contains the category helps in mapping
13:54:50 [alex__]
what is qdos?
13:54:50 [Ronald]
gary: being the first to implement the W3C standard is good for your company
13:55:01 [Ronald]
kudos
13:56:06 [Ronald]
alex__: standardisation will help more people to create content
13:56:27 [Ronald]
alex__: end value seems to lie in the extensibility, but we should not underestimate the power of the core
13:56:45 [Ronald]
karl: separating of the location from the POI is useful
13:57:13 [matt]
[[ I poked around looking for free/cheap YP databases, and I am distressed at how limited the data set is: ID, Categorie, SubCategorie, Name, Address, City, State, Postal Code, Phone, Fax.]]
13:57:40 [Ronald]
gary: every current system embeds the location in the information, and it gave an editorial nightmare
13:57:48 [Ronald]
s/gave/gives/
13:58:19 [Ronald]
gary: POIs are human artifacts and can change, but locations are static
13:59:19 [Ronald]
gary: principles are good, but it will take effort to flesh out the primitives provided in the principles
13:59:43 [Ronald]
gary: we have a skeleton of a draft recommendation, but we have a lot to flesh out to get the draft recommendation

-> http://www.w3.org/2010/POI/wiki/Terminology Terminology
14:00:43 [Gary]
Gary has joined #poiwg
14:00:53 [Ronald]
matt: lets review terminology page and check if it fits the things we discussed
14:01:30 [Ronald]
gary: should be an action for post F2F to reflect the new reality we defined
14:01:53 [Ronald]
andy: are we done with the use cases
14:01:53 [matt]
ACTION: Gary to scrub wiki and terminology pages to reflect consensus notion of location and place terms
14:01:54 [trackbot]
Created ACTION-23 - Scrub wiki and terminology pages to reflect consensus notion of location and place terms [on Gary Gale - due 2010-12-22].
14:02:10 [Ronald]
alex__: no, let's go over them all
14:02:41 [Ronald]
alex__: location is broader than the current definition, it is any type of attribute to define the location
14:03:05 [Ronald]
alex__: computer vision might be used to detect the an object and use that as the location
14:03:22 [Ronald]
karl: is it a landmark that can be recognized?
14:03:47 [Ronald]
alex__: yes, but we may not care about the location, but we know that the object is in front of the user
14:05:20 [Ronald]
gary: instead of computer vision, can we call it proximity sensor, as that covers much more
14:05:38 [matt]
PROPOSED RESOLUTION: A location may be a number of things, including: wgs84 coords, civic address, a vector with absolute or relative positioning, minimum bounding rectangle, unknown, a 3d model, or (?? computer vision stuff)
14:08:27 [Ronald]
gary: is proximity something we should include? it does not specify the location
14:09:17 [Ronald]
gary: if you just use proximity, you still don't know your location. all you know is that you are close
14:12:40 [matt]
PROPOSED RESOLUTION: A Proximity Sensor is something that determines the location of something else relative to the sensor.
14:12:50 [matt]
Gary: No, it doesn't tell you the location, just distance
14:13:04 [matt]
alex__: That's maybe a technological limitation that you're carying.
14:13:08 [matt]
Gary: I think it's out of scope.
14:15:43 [matt]
matt: I think we are all comfortable with wgs84, even if it is getting updated next year, addresses, a pain in the neck, but understood, going down the list? 3d model? proximity sensor? How do we pick what those are and how we represent them?
14:17:09 [matt]
matt: Can we say something like "proximity" rather than "proximity sensors"? e.g. standardize on "I am within X meters of Foo_POI and Y meters of Bar_POI and Z meters of Bang_POI" -- what those POIs are -- bluetooth sensors, whatever -- is irrelevant.
14:17:58 [matt]
scribe: Matt
14:18:34 [matt]
Gary: With RFID you're saying things like "this parcel is now in this warehouse"
14:18:44 [matt]
Gary: I'm okay with relative location.

14:20:16 [matt]
PROPOSED RESOLUTION: A location may be a number of things, including: wgs84 coords, civic address, a vector with absolute or relative positioning, minimum bounding rectangle, unknown, 3d model, TBD relative location spec
14:20:28 [matt]
matt: Is an MBR just two WGS84 coords?
14:20:56 [matt]
Gary: In it's pure form it's a spatial box with minimal information. Always two opposite corners. Using a positioning coordinate system.
14:21:21 [matt]
Gary: In this world it's typically two Cartesian points relative to WGS84.
14:21:44 [matt]
kseiler: The footprint and MBR seem similar, MBR being a subset of footprint.
14:22:36 [matt]
alex__: I was going to flesh out extents for this meeting.

14:23:27 [matt]
alex__: Extent and location are related in that it's you can derive a location from MBR extent.
14:23:28 [cperey]
hello
14:23:32 [matt]
Gary: sometimes it's all you have though.
14:23:45 [matt]
alex__: The breakout may have real value though.
14:23:52 [matt]
Gary: Extent I think is an attribute of location.

14:29:38 [cperey]
yes! I hear you
14:29:51 [cperey]
I was listening!
14:30:21 [matt]
cperey: I sent a message to the list saying it's sometimes absolute and sometimes relative.
14:30:24 [matt]
ack next
14:31:16 [cperey]
location is a point in place. three dimensional world
14:31:30 [cperey]
can be absolute. can be relative and can be inferred
14:31:38 [cperey]
+1 on that last statement
14:31:46 [matt]
alex__: Location is a point in space somewhere with an extent around
14:31:49 [cperey]
technologies which can be used to infer where you are from other data
14:31:52 [matt]
Gary: They can be relative and infered.
14:32:06 [cperey]
used as a feedback cycle to verify the veracity of the data you have received
14:32:16 [cperey]
relative to some frame of reference
14:32:32 [cperey]
but you also have to have explicitly called out so that it is workable
14:32:58 [cperey]
if we start throwing around semantic terms such as relative, we will ignore it. Real world workable
14:33:35 [cperey]
gary says: sure, you could argue that location is a relative system, but include that it includes relative frames of reference to other points, potential, to oursevelves, to a device, or relatie to an adress
14:33:42 [matt]
alex__: We need to codify that it can be relative to things via proximity, or relative like an address, or 100 meters from blue house.
14:34:05 [cperey]
as long as we agree that we have relative frames of reference...
14:34:24 [matt]
alex__: While we're deep in location, let's talk about this notion of where is something.
14:34:44 [matt]
alex__: The driveway to the McDonalds really matters, but some people would argue it's just part of going to McDonalds and it's just extra data.
14:34:48 [cperey]
Karl said (recapping) is this notion of where is something (discussion about driveway to McDonalds) is just a part of something ELSE, the "extra" data
14:35:16 [matt]
alex__: How are we going to codify these things as they get more complex?
14:35:32 [matt]
alex__: I say we associate them with further points of interest.
14:35:47 [cperey]
Alex feels we should go with basic principle that there is no short list...a POI is any place you would want to go
14:36:35 [matt]
PROPOSED RESOLUTION: A location may be a number of things, including: wgs84 coords, civic address, a vector with absolute or relative positioning info, a minimum bounding rectangle, unknown, a 3d model w/wgs84 or TBD relative location spec,
14:37:04 [matt]
Gary: Yesterday I tried to push name into location, but we decided location is where it is, everything else is in this other bag called place
14:37:10 [matt]
s/Gary/Karl/
14:37:29 [matt]
Karl: Place is the bag for everything else: names, locations, ids, etc.
14:37:45 [matt]
alex__: We think this method is maybe how increasing fidelity is dealt with.
14:38:11 [matt]
alex__: It's a bit scary how much data there will be.
14:38:20 [matt]
andy: Didn't we eliminate known or unknown?
14:38:27 [matt]
s/known or//
14:38:52 [matt]
karl: Maybe a business is forming, but has no location yet. Can it have a POI?
14:39:55 [matt]
alex__: There's some semantics on pointers being null, whatever, but what's important here is if Alex's office is contained within the TSRB and it exists as a POI, is it okay that it's location is unspecified further.
14:40:38 [matt]
alex__: Maybe it has no parent and has no location it has little value, but they exist.
14:41:16 [matt]
andy: Example?
14:41:27 [matt]
alex__: A welcome message.
14:41:58 [cperey]
this has a location, I simply don't know where it is at the moment
14:42:04 [cperey]
this was suggestion by Matt
14:42:13 [cperey]
still come back to the loosey goosey of the word POI
14:42:15 [matt]
matt: I think there is value to having an "unknown" location rather than just no location.
14:42:38 [cperey]
place vs. stuff
14:43:04 [matt]
karl: McDonalds a store vs McDonalds as a whole thing. One is a place the other isn't.
14:43:36 [matt]
alex__: My car for instance, I can tell where it is until I'm in a tunnel. Then I could probably guess with low accuracy that I'm still on earth. Place seems a bit rigid.
14:44:27 [matt]
alex__: A person, place, or thing -- there are extremes that make your hair stand up, but there are real things like OnStar trying to find my car, then there are places that might not have a known location.
14:45:10 [matt]
Gary: I don't see why there isn't a way for people to create things from places that we've described here, but I think it's a minimal edge case. So minimal we should move on. No reason you can't do this, I would question why, and if you wanted to, you wouldn't call them places.
14:45:17 [cperey]
NO this is not all about places
14:45:40 [cperey]
that is a negative attitude
14:45:46 [cperey]
on the contrary
14:45:53 [cperey]
AR is very general topic
14:46:19 [cperey]
thank you, Alex
14:46:22 [matt]
Gary: This is the POI working group, so we're about places.
14:46:33 [matt]
matt: I see no reason why we shouldn't be working towards such a thing.
14:46:42 [cperey]
let's not hamstring to the point where people can't use it that way
14:46:46 [cperey]
we're not creating the theory of stuff
14:46:53 [matt]
alex__: Let's not hamstring it so that it can't be done this way.
14:46:55 [matt]
Gary: We're not creating ethereal stuff, we're agreeing on what a place is.
14:46:56 [cperey]
we're creating a workable definition of ...
14:47:16 [matt]
Gary: We agreed on what a place is yesterday.
14:47:19 [cperey]
I didn't see that agreement
14:47:20 [matt]
matt: I think unknown location is still key.
14:47:28 [cperey]
was it sent out to the list?
14:47:41 [matt]
Gary: We have to have temporal and unknown locations sure.
14:48:06 [matt]
Gary: We have to say the location is unspecified/unknown.
14:48:48 [matt]
alex__: I want to make sure the door isn't slammed in the face of these esoteric use cases.
14:49:10 [matt]
andy: I would prefer we didn't say they're esoteric, I think there's far more use cases for stuff than places.
14:49:19 [matt]
Gary: But this isn't the stuff WG.
14:49:34 [matt]
Gary: We're not here building a data model of everything in the world and their relationships.
14:50:02 [matt]
andy: I think the movie poster is a POI and it has an unspecified location.
14:50:16 [matt]
Gary: I'm saying it is too, but it has to explicitly have an unspecified location. If you make it optional --
14:50:18 [matt]
andy: I think that's fine.
14:50:28 [matt]
alex__: The movie poster is in front of you, it is a location.
14:50:33 [matt]
andy: It's just not important.
14:50:45 [matt]
alex__: It is. Someone could walk in front of it and the information goes away.
14:51:07 [cperey]
+q
14:51:11 [matt]
alex__: If you take out where it is, just recognize that there is a movie poster, then go to a website, that's not a POI.
14:51:33 [matt]
alex__: POI is about where it exists in the world.
14:51:50 [matt]

14:53:23 [cperey]
thanks matt :-)
14:53:24 [matt]
andy: In location based advertising, pushed info or whatever, those have locations?
14:53:35 [matt]
alex__: They do matter where you are.
14:53:44 [cperey]
this is exciting and I understand 100%
14:53:47 [matt]
alex__: Those are about POIs definitely.
14:53:53 [cperey]
I would rather you SCRIBE
14:53:59 [matt]
karl: What's the point? To drive you to the store front.
14:54:02 [cperey]
than pay attention to me
14:54:03 [matt]
s/front./front?/
14:54:17 [matt]
gary: Geofence advertising is based on position, proximity and your movable point and radius.
14:54:55 [matt]
gary: a geo-fence is not a place, it's a boundary trigger.
14:55:25 [matt]
gary: What we're doing here with place intersects with boundary, and geo-fencing and boundaries intersect on the other side, but doesn't imply that geo advertising is part of place.
14:56:53 [matt]
Gary: You may utilize a place based repository to figure out where the geo boundary occurs, e.g. these POIs for Arbys are here, and the geo-fence is therefore around them.
14:57:25 [matt]
Gary: We said Chicago is a place, but it's an abstraction. I don't think you are going to stop people from creating abstract places with this spec.
14:57:54 [matt]
Gary: But it doesn't mean it's part of geo based advertising. You can setup a fence without knowing the place: just the vector that describes it.
14:59:23 [matt]
alex__: Is it unreasonable to have a Theater District described by this spec to then fire off a coupon?
14:59:39 [matt]
Gary: Yes, but place is not fundamental to the concept of location based advertising. Place is just one tool to define a geofence.
15:00:20 [matt]
alex__: If people use this spec for this, do we need some other construct to achieve that or can they use/abuse POI to do that?
15:00:33 [matt]
Gary: You can create Karl's geofence.
15:01:15 [matt]
Gary: Going back to small granular POIs: we can create a place for this table in this room, and you can say I'm going to derive a geofence from that place. That will fire whenever I'm within a foot of this table. I know it's a place, I know it's extent, I've got a vector that describes it's shape.
15:01:58 [matt]
Gary: Within a meter, it sets off a coupon or whatever. But as an advertiser, I can make a vector trace somehow [walks around table], I don't need the table to create it, the table is just a stepping stone.
15:02:16 [matt]
Gary: One is a tool to create the other.
15:03:11 [matt]
Gary: The point is you can have a geofence without a place.
15:03:55 [matt]
Gary: Most geotargetted advertising looks at say, newspaper press zones and those zones have these zips, and then aggregate those together and make the vector and then target those.
15:04:54 [cperey]

karl: I think we're fleshing out what the name primitive is.
15:25:50 [matt]
karl: I think we should also consider a label.
15:26:02 [cperey]
I like label, but express that as a "trigger"
15:26:04 [cperey]
+q
15:26:27 [matt]
karl: Common name, etc, different names for the same thing.
15:26:53 [matt]
alex__: I was assuming from the get go that name would subsume that. That we don't need another field for that sort of thing.
15:26:59 [matt]
karl: Name consists of a UTF string plus a language code and a label.
15:27:20 [matt]
Gary: Normalized form of the address could be used to populate the name primitive.
15:27:36 [cperey]
is this an IETF classification code topic?

I want to wait until I have the floor :-/
15:29:11 [matt]
Gary:180 Lunvaden Straße and 180 Lunvaden Strasse and 180 Lunvaden Str are all the same thing.
15:29:44 [matt]
karl: We need the name, the language code, and then there are all sorts of vanity addresses that exist.
15:30:04 [matt]
ack next
15:30:54 [matt]
Gary: There are all sorts of valid names, maybe we need a textual primitive, a unicode text string together with the language code that is then used.
15:31:06 [Gary]
It's Invalidenstraße by the way :-)

15:35:26 [matt]
alex__: If a POI establishes that there is something at a location, or somewhere, it has an extent, I might bump into it or say something to it or whatever. So, what defines the interactivity between me and it. A div on a website that's clicked for instance is a trigger. So what's the trigger mechanism between my behavior and POIs?
15:35:42 [matt]
alex__: I think that Christine was saying that there be some linkage between the name/label and triggers.
15:35:45 [cperey]
Yes, I was asking if there
15:35:47 [cperey]
is a connection
15:36:03 [JonathanJ]
we need to consider the I18N(Internationalization) of POI. Ref: http://www.w3.org/International/
15:36:16 [cperey]
but a little bit no!
15:36:22 [matt]
Gary: Isn't that an application level thing?
15:36:28 [matt]
alex__: It's on the borderline of being out of scope.
15:36:41 [cperey]
if you define a label/extensions, then you have to be able to use the extensions
15:36:58 [matt]
alex__: There's extensions and extensibility for things down the line for AR, but it's not obvious to me that it needs to be built in.
15:37:08 [matt]
Gary: That seems like a business specific specialization.
15:37:53 [matt]
Gary: Does this trigger metadata be part of the place itself? It's one way you'd facilitate discovery of the data based on this, but it is but one of a multitude of business specific specializations. It could almost be a use case.
15:38:44 [matt]
alex__: On one hand it sounds like geofencing. There's information within a POI that would facilitate that, but there is also other information that may help. There's a tacit implication that the discovery will come from things like a geospatial search. The notion of a trigger could get more rich down the line.
15:39:03 [matt]
alex__: Imagine a future where a proximity searched doesn't matter, but what I can see is the search.
15:39:07 [matt]
karl: That's not even the future.

15:40:02 [cperey]
Matt I need to change phones. I'll hang up and dial back in
15:40:03 [matt]
alex__: If only information a POI has is lat/lng coordinates, you can't do that type of search, but with richer info you can do different types of searches.

address representation
15:47:12 [cperey]
that sounds important for me to have heard
15:47:35 [cperey]
will those standards bodies be at the International AR Standards meeting in Feb?
15:47:47 [cperey]
IETF
15:47:56 [cperey]
they have 50 fields
15:48:21 [cperey]
complicated, GeoLocation WG decided on 12 fields
15:51:47 [cperey]
If I ask for POI and I get back a string, I get the POI from the string, I have to hand it off to a service to do anything with it
15:51:57 [cperey]
if , at that data exchange level, have we created enough?
15:52:11 [cperey]
we (NOkia) have to GeoCode official address and relative addresses
15:53:45 [cperey]
you are telling me rightnow, if I have a normalized text string, there's enough information in that.
15:53:59 [cperey]
there's some service which I can start talking to to get more detailed informatoin (Alex)
15:54:10 [cperey]
is that Karl?
15:54:12 [cperey]
or who?
15:54:18 [andy]
yes
15:54:22 [andy]
karl
15:54:31 [cperey]
Alex: when you say preferred service you mean, what exactly?
15:54:58 [cperey]
Alex: this is a big issue. I have some data. Now I want more, what do I do?
15:55:10 [cperey]
Alex: I got a POI, great, but I really want more...What happens?
15:55:24 [cperey]
Karl: we had it at too high a level. You want URIs for ???
15:55:32 [cperey]
chop chop (can't hear)
15:55:44 [cperey]
who is scribing?
15:56:11 [cperey]
thanks matt
15:56:13 [matt]
karl: I'm trying to get in the spec a URI primitive so that someone can attach a service to a piece of data.
15:56:25 [matt]
alex__: Other bodies must have tackled this issue.
15:56:45 [cperey]
cperey agrees with alex_
15:57:02 [matt]
Gary: Isn't this the same problem as going to the post office and you end up shoe-horning another countries address format into the form? I appreciate the sentiment, but isn't it meaningless except to other implementors who implement it the same way.
15:57:21 [matt]
karl: I was thinking every primitive could have a URI attached to it.
15:57:46 [matt]
karl: All of the primitives have an URI, and then when looking at an address you could use the URI to render that address.
15:57:53 [matt]
karl: (render, geocode, whatever)
15:57:54 [JonathanJ]
+1
15:58:13 [matt]
karl: You give this URI the address and I'll give you a fully extricated location.
15:58:29 [matt]
alex__: I give you a link for say a car, and you could use a URI to find where the car is?
15:58:52 [matt]
karl: It's like the category primitive. You could get more info about it when using the URI.
15:59:40 [matt]
alex__: My hesitancy is similar to my hesitancy to adding timestamps. It's a potential explosion of the data model. I agree whole heartedly with the notion, but I hope we can find a more succinct way than tacking on all over the place.
15:59:55 [matt]
karl: I have the same comment on ID. What is it?

16:30:04 [matt]

matt: POI Core Recommendation
16:31:56 [matt]
alex__: And do these have the use cases in them typically?
16:32:14 [matt]
matt: Some times in the doc, sometimes separate Note, sometimes just a web page that's referenced.
16:32:23 [matt]
karl: We can have them, put them in an appendix, whatever.
16:32:37 [matt]
alex__: We can have examples that demonstrate a typical use case that we'd have.
16:32:47 [matt]
alex__: i.e. a typical POI with a wgs84 location, name, etc.
16:33:58 [matt]
Gary: How do we document the data model with examples unless we chose some normalized XML schema that we knock together.
16:34:16 [matt]
alex__: We're not going to XML out an example today.
16:35:41 [matt]
alex__: We agree there's an example section.

matt: I think we'd like people to volunteer to help.
18:54:40 [matt]
Ronald: I can fill in some information about the European offerings.
18:54:43 [matt]
alex__: I can contribute too.
18:55:12 [matt]
alex__: The AR Tagging struck me as specific.
18:55:28 [matt]
alex__: You could imagine AR balloons, or new construction, or a tweet over your head.
18:55:36 [matt]
s/AR Tag/Air Tag/
18:55:47 [matt]
alex__: Maybe something a bit more generic than Air Tagging, like "user generated content"
18:55:54 [matt]
alex__: Addressing user interaction -- UI is a big issue.
18:56:26 [matt]
alex__: Some capabilities discovery needed -- processing power to run FLAR type stuff.
18:56:54 [matt]
alex__: I would point you at a paper we submitted to ISMAR that wasn't accepted. I can send that to you.
18:57:17 [matt]
alex__: I think it is valuable for someone to survey the existing technologies.
18:57:27 [matt]
alex__: Not a big list: feature tracking, marker tracking, GPS tracking.
18:57:38 [matt]
Ronald: What does it support on those levels?
18:58:06 [matt]
alex__: That's useful, but to me the interesting part is how people author this? How do they describe what they want to do? Is it interoperable?
18:58:47 [matt]
alex__: We need AR to become something like the Web, where I can put up content and people will be able to consume it.
18:58:56 [matt]
Ronald: I think the survey should focus on those aspects.
18:59:13 [matt]
Ronald: I'm not sure how FLAR or marker based AR fits in. Are you going to put them all into one class?
18:59:31 [matt]
Ronald: Or are you really targeting the platforms, the browsers, those with lots of content?
19:00:03 [matt]
alex__: When I saw the demo at the AR Standards workshop it was on a handheld. The X3D stuff seems oriented towards making this work on mobile devices.
19:00:25 [matt]
alex__: A lot of the conversation with Khronos involved low level device protocols.
19:00:43 [matt]
alex__: Nokia had a camera spec, etc.
19:01:00 [matt]
alex__: There is this whole stack from low level to high.
19:01:12 [matt]
Ronald: Important for us to look at these initiatives.
19:01:23 [matt]
Ronald: There's lots of platforms that would benefit from such a standard.
19:01:49 [matt]
alex__: When we're looking at AR here, are we talking mobile or desktop?
19:01:54 [matt]
JonathanJ: No, AR on the Web
19:04:19 [matt]
alex__: Standardization will be coming from the mobile direction, rather than HMDs, desktops, etc.
19:04:26 [matt]
Ronald: Agreed, and we'd definitely help support this.
