Relationships Minutes from F2F
[16] http://www.w3.org/2011/03/31-poiwg-minutes.html#item09
cperey: It was treated at the f2f on the third day. I would say
close the item and create a new one that reflects the minutes.
karls: Does the same apply to the anchor and extent definitions?
cperey: We didn't treat those subjects at the f2f.
close ACTION-25

[17]http://www.w3.org/2010/POI/wiki/Core/Draft#Relationship_primitiv
e Relationship Primitive in Core
[17] http://www.w3.org/2010/POI/wiki/Core/Draft#Relationship_primitive
matt: I think this is my duty as temporary editor to go through f2f
minutes and make sure the draft reflects that now.
cperey: We had a great discussion on this, comparing it to OSM. At
OSM they're not clustered, but can be sequenced, etc.
ahill2: I think we got a real sense of the difference between the
hammer that is OSM and what people think of as POIs. How that turns
into a reformulation of relationships is a TBD.
POI relationships, identifiers, registries, and services
<scribe> ACTION: Matt to update core draft Relationships Primitive
to reflect what we learned at the f2f [recorded in
[18]http://www.w3.org/2011/04/06-poiwg-minutes.html#action02]
<trackbot> Created ACTION-53 - Update core draft Relationships
Primitive to reflect what we learned at the f2f [on Matt Womer - due
2011-04-13].
cperey: We have an opportunity to create relationships that don't
break OSM's policies. Not saying how, but the knowledge from that
subject is there.
ahill2: I concur that yes, I think one of the outcomes of this is
that we develop the notion of relationships in POI that is sensitive
to the types of relationships that OSM considers and that we can be
clear on delineating differences there, rather than before where we
would have just stumbled into it.
karls: Do we have a member of the group who has that kind of insight
to OSM?
<cperey> proposed meeting to foster relationships with OSM commnity
in September
<cperey> Jacques provided a tutorial on OSM on third day. Helped to
frame the context o OSM
matt: I think Jacques is closest to the data. Plus we've got on the
list of potential F2F locations as one that's co-located with the
OSM meeting in September (also co-located with OGC)
<cperey> good little primer and a lot of people better understand
the situation with OSM
ahill2: On the third day we got a primer on OSM from Jacques. He
would say it's simple, what else is there to say.
<cperey> we could ask him to provide the tutorial as an invited
topic?
matt: With OSM we should be careful though, as we have different
concerns. We can just update our database if we change something,
we're distributed, etc.
Raj: Was there any talk of linked data and OSM?
ahill2: It's a single database, and people are building on top of
it, but when we asked if people are linking across data, he didn't
think that was something that happened.
... e.g. you might build an app on top of OSM that has a level of
abstraction on top of it, but he didn't really have a good answer
for linking between data bases and referring to IDs outside of the
one OSM database.
-> [19]http://linkedgeodata.org/About Linked Geo Data
[19] http://linkedgeodata.org/About
matt: We did talk about linkedgeodata, which is extracting OSM data
and making it linked data friendly.
ahill2: They also provide a SPARQL API.
matt: And a REST API.
Raj: So OSM is successful but people when building their apps are
what, copying the data and building on top of it?
karls: How do you mean copying?
Raj: For instance, Google is supposedly using OSM data, but I doubt
they're hitting OSM servers, they're downloading the data
presumably.
... In other words apps aren't using it online, they're copying it
and building apps on top.
ahill2: I think that's a fair description.
matt: Certainly on large apps.
karls: I can understand Jacques pause. It relates to ID management
outside of the database.
... Our stuff will be going across many data sources. We got to
unique URIs.
ahill2: One topic was how to engage the OSM community. It's
organized in a different manner than say OGC.
... Jacques was encouraging us to get in the forums, etc. But that
doesn't really give us someone to engage with, to invite into the
group and collaborate with us.
<cperey> +1 to this recommendation/and the lack of someone to
contribute
<scribe> ACTION: Andy to find someone within OSM to collaborate with
[recorded in
[20]http://www.w3.org/2011/04/06-poiwg-minutes.html#action03]
<trackbot> Created ACTION-54 - Find someone within OSM to
collaborate with [on Andrew Braun - due 2011-04-13].
<cperey> I'm just preparing the "how to invite experts to contribute
to our domain knowledge" (one of my action items)
Raj: We need more people at the table, Facebook, Gowalla, etc.
Talked with someone from Simple Geo, and he had problems with this.
The barriers are high right now.
Andy: I talked to both Gowalla and Foursquare and I don't think
either of them have the bandwidth to participate in creating the
documents.
... Foursquare is interested in reviewing. As we get drafts it's
worth sending it to them, but I don't think they have the bandwidth.
Raj: I think we can get over bandwidth hurdles if we can get real
commitment and interest.
ahill2: We had some discussion of this at the F2F about
participation.
-> [21]http://www.w3.org/2011/03/29-poiwg-minutes.html#item05 Some
participation discussion
[21] http://www.w3.org/2011/03/29-poiwg-minutes.html#item05
ahill2: I've heard some motivation of being able to brand data as
W3C compliant, but I can't imagine that's a strong motivating factor
to smaller companies.
... We have to be sensitive to some of those motivations.
fons: I just had a discussion with someone at TomTom, and it seems
that they are interested in at least participating in the WG. I
tried to get them to become a W3C member first, but if they can't do
that, then it might be interesting to have them in the WG as an
invited member.
karls: From Nokia/NAVTEQ/MS, I think anyone in the map business is
very interested in facilitating local search. The hinge point there
is on POI definitions. We're all looking to build the largest most
robust POI database.
... We need standards for that to ensure the widest participation.
We're very interested in making this work.
Andy: I think there is lots of interest from big guys, but smaller
ones don't have the same motivation to build the largest data set.
Their stuff is community driven, etc.
karls: We might start with commercial data, but our end goal is to
have community.
Raj: That's a great statement. I think we don't need every one of
them, but I think we need more sides of the coin here. Otherwise,
we'll keep going around in circles about the core data definition.
karls: Makes sense to me.
ahill2: Karl, can you elaborate a bit? You've got a proprietary
database of POIs and you would like to have a product that is
drawing POIs from other sources on the fly and that that would be a
good motivation for a standard?
... Or do you want it easier for you to purchase POIs or acquire it
that it comes in in a palatable way for integration into the
database?
karls: There's an arc we are projecting. We're trying to build out
platforms that we can put in a consortium space that is a single
unified repository for places, locations and relationships. We're
going to feed that content with anything we can license to get to
critical mass as fast as possible -- you have to achieve a tipping
point in volume for it to attract users -- but once that is hit, the
intent is that it is open.
... We could extend the base records we have with licensed data for
instance.
... But that last part is not what we should strive towards. A
standard that drives us toward participation is what we need.
... We've got islands of information that we want to bridge.
Raj: That sounds like a great business use case.
... Something like that could drive the core data format. e.g. we
could have where the location is in the standard, but maybe the open
hours changing could be a proprietary extension.
karls: Could be. We really also want to facilitate in a wikipedia
way the repair of the database.
... The standard needs to allow to happen or provide governance on
change management.
... POI have much shorter shelf life than maps.
... Extensibility and flexibility are important too.
Raj: Change management to me requires unique IDs to me. What if
change management came out of updating those URIs? Maybe it doesn't
take a huge data model just a few key things.
karls: If we could figure that out it would be a real accelerant for
the whole thing.
ahill2: Can you elaborate on that a bit Raj? A simple example?
Raj: We can't predict ahead of time everything that could go into a
POI, but say we put 90% of our energy into the unique ID. A point
location, a name, a start and end time. Then when people want to
collaborate they know they are talking about the same object because
they have a unique ID.
karls: We've talked about DNS IDs.
Raj: if the unique ID were in there, the rest could fall out from
that.
ahill2: We had a lot of discussion with Thomas Wrobel and Dan
Brickley about semantic entities like dbpedia, etc that are
providing unique URIs to known things.
... e.g. a URI for a horse, cow, dog, etc. I took away from that
that instead of a single registry there might be a couple, e.g.
dbpedia, library of congress, etc.
... Each managed in some sense like wikpedia, etc. Then there's a
more rigid model of DNS like. Which direction should we go?
Carsten: I think you can push the wider model open by saying you
don't have a registry, just the Web itself. Lifecycle management is
harder on the Web, but strong on DNS.
... I think this is the right direction: minimal data model, effort
on unique ID and making sure the data can be linked up.
karls: I agree with everyone that the ID, any work we can do around
that is the anchor. Rich location definition is important too.
Relationships, being open ended, is important too.
... I don't think we can go far beyond ID, location, relationships
and attributes.
Raj: In the DNS model if we had some governance people could get
their unique ID for a POI and then it gets propagated around the
world.
karls: That's what Navteq is building in their POI registry. They
intend to not own that in the long haul, that it should go into a
consortium controlled space.
ahill2: In DNS you get competition for different domains, etc. Can
anyone comment on what they think on that?
... We want a model where it's not owned, right?
Raj: Right. Who owns DNS? ICANN? And Wikipedia is governed by an
organization, and has a lot of governance. If you put a bad article
up there they won't publish it.
karls: Content moderation is key, current and accurate is immensely
valuable.
... I think the standard should support the basic construct of
changes, owners, etc.
... Timestamps to know that it is current and accurate.
<cperey> +1 on that
<cperey> moving from a data-oriented discusion to a services
oriented discussion
matt: We talked a lot at the f2f about talking in terms of HTTP and
XML. I think we won't have to define lots of stuff around this, but
provide guidance, e.g. "if POI data changes, when the URI is
dereferenced, this HTTP header is produced to redirect to the
updated one, cache tags are used, etc."
... This stuff we need to do to make it fit in the Web architecture
needs to be figured out, not just the data.
Raj/karls: This sounds like we're moving from data defining to
service defining.
karls: If we can't imagine that the standard doesn't facilitate the
creation of a consortium that has governance over the quality, then
I think we haven't hit the mark.
<cperey> I cannot extend
<cperey> no problem

matt: details options
cperey: In addition, there is an AR Standards meeting in Taiwan, on
June ??. Karl will be there, and Martin, maybe Jonathan and Jim?
... My hope is that regardless of where it is, having a meeting
hosted in conjunction with another event is highly desirable.
matt: I updated the f2f poll to reflect AR standard smeeting too.
cperey: When/where does the group want to work on the drafts, and
when/where does the group want to interface with other groups and
share?
Raj: Is there an option for four?
matt: Sure. We say 2-3 in the charter, but that's to estimate how
much time people can spend, if the group wants to meet more, sure.
More on POI relationships, identifiers, registries, and services
ahill2: It has been unclear up until now how the format will be
used. This discussion about registry makes a lot of sense.
... I think the service idea is quite compelling.
<Carsten> Got to go as well, bye
matt: Maybe someone can take an action to look at current proposals
for registry type stuff? And maybe another for how this stuff can
fit in the Web architecture?
Raj: Sounds very open ended?
matt: Just starter stuff.
ahill2: Could someone report back on registries out there? I know
they are known to people, but maybe a listing of various dbpedias,
library of congress and other attempts to create registries of POIs?
Maybe some commentary on policies? How they manage change?
Centralized authority? Editorial board? Vote up/down?
karls: I'll take that action. I'm building out a content management
group as we speak, and so have had some look at things similar to
this.
