__________________________________________________________
As only 4 memebrs were present, an informal meeting was held.
<trackbot> Date: 19 August 2015
<Frans> I wonder if more people will show up
<scribe> scribe: phila
Frans: Main topic is the homework that people have been done
... It's not clear who is doing what homework. There were some
action items but not for everyone
<Linda> There's some minor construction work going on in our
office so it could be noisy in my background.
General agreement that we are not quorate so we'll have an
informal chat
Cross referecning homework
Frans: I saw 2 action items

ives Narratives Page
[11] https://www.w3.org/2015/spatial/wiki/BP_Consolidated_Narratives
jtandy: There are 7 narratives on that page
... and an 8th that I haven't worked out what to do with yet.
Was there any discussion about the other stuff
phila: Is pretty sure that no, the 'other stuff, hasn't been
classified
jtandy: We can come back to the other stuff anotehr time. There
are things there that we should cover. Like how to we handle
large aounts of data that don't fit into an RDF-centric view of
the world
Frans: We did discuss the narratives in general... one idea was
to have the amateur vs expert perspective
... The big datasets might fit into the expert aspects of a
data publisher
jtandy: And there's stuff that talks about lineage and
provenance (the data linking bit). How to do linking when it's
5TB of LIDAR data
Frans: You could probably group a lot under such a narrative, a
researcher wanting to publish data in a meaningful way
... It also seems realted to the diff between publishing a web
page with some microdata and publishing an entire dataset
through a service endpoint
jtandy: Any highlights about the discussions about the 7
narratives as laid out?
Frans: I don't think were discussed in depth. The main topics
have been finding volunteers to do the cross referencing work
... And before that we discussed the nature of the narratives
but that was before they took form.
jtandy: I think I have a quick run through 3 weeks ago.
<Frans> jtendy: current format of narratives looks a lot like
the format of the Data on the Web BP
jtandy: Is DWBO meeting at TPAC?
how to communicate with the Data on the Web WG
phila: No.
jtandy: There are things that we want to say that may be
applicable beyond spatial data, but we'll say it in the context
of spatial data. DWBP might want to broaden it
... and we'd help them do that, but we should keep delivery
decoupled
phila: Dependencies either way are bad
<Frans> phila: I think I am the only member of both groups
Discussion about DWBp relationship. Agreement that liaison
doesn't mean dependencies.
If DWBP has a BP that is useful/applicable, SDW can cite it,
modulo any changes that SDW might ask for
Problem only arises if the two BP docs present best practices
that are not in alignment/contradictory
which is unlikely
<scribe> ACTION: Archer to invite Hadley Beeman to a meeting
with the SDW WG at TPAC [recorded in

[12] http://www.w3.org/2015/08/19-sdw-minutes.html#action01]
<trackbot> Created ACTION-68 - Invite hadley beeman to a
meeting with the sdw wg at tpac [on Phil Archer - due
2015-08-26].
Discussion of wiki page to be established to record areas where
SDW thinks a Bp should/could/might like to cover an issue
Frans: The prob with the DWBP is that the scope is so broad
phila: Yes
Frans: So we should protect our scope
... I think it would be useful to list things that we think are
important but that re out of scope for our WG
jtandy: That's a meta question for how to cross reference.
... I wonder whetehr we should go through the homework as best
we can
... In terms of cross referencing, Kerry has put some stuff in
about linking data, Ed has done the same about APIs, Linda has
put in some stuff about enablign discovery
... Nothing on identifiers, spaitiotemporal
... Linda, could you talk us through what you discovered for
enabling discovery
Linda: Mainly what I found was that the DWBP doc there was a
big section about metadata
... the point of providing it, largely for discovery, so
there's an overlap there
... so we should take a good look at thats section. And then
maybe extend it with spatial aspects
... Anotehr thing they mentioned was that discovery depends
fundamentally on the use of HTTP URIs - which is right
jtandy: Both of those sound like sensible observations.
Extending existing BPs, and use of HTTP URIs which Phil is
looking at
... I see there wasn't any coverage of Architecture of the
Web/inconsistencies
... That's been around a long time and it's remarkably relevant
today. So we need to be consistent with it if we're talking
about spatial data on the Web.
... We are consistent with it
Linda: Yes, just more specific
jtandy: Are there other citable resources that we should be ...
citing
Linda: I'd have to think about it.
phila: Maybe some OGC stuff?
Linda: Some OGC, INSPIRE??
jtandy: There's the DCAT-Geo-AP
... that's expressing ISO19115 plus DCAT etc.
... Things like DCAT-GeoAP should be consistent with what we're
saying.
Frans: That looks like a BO to me already
jtandy: That's more than a BP
... It says if you're going to use 19115 attributes, then do it
like this - that's more detailed than we want?
Frans: People are looking for that kind of guidance. It's a
mapping from OGC to W3C mapping, it's what publishers are
looking for
... I;m not saying that it is a BP, but it's a good candidate
... that might be identified in the deliverable
<Frans> Linda: missing discovery of data vs. discovery of data
sets in DotWWG
phila: Bangs on about longevity, give examples, maybe on
example - comply or explain maybe
<Frans> phila: yes, that is an issue and the DotWWG should
tackle it
Linda: Does it talk about data on the Web cf. datasets on the
web?
jtandy: Thank you for doing your homework. I was very pelased
to see stuff happening even though i hadn't push it
<Frans> jtandy: pleased to see stuff happening
phila: (Kerry was pretty forceful last week)
jtandy: We could look through what Ed and Kerry wrote or do it
offline
Frans: I think it makes more sense if more people are present
... esp Ed and Kerry as they wrote their contribution
jtandy: Ed has put in BP23, 26 and 22
... so he's been though it and put some brief notes in
... Regarding next week, I'll be on vacation again
phila: Me too
Frans: I am being forceful too - do your homework
<Linda> Me too - on vacation next week I mean
jtandy: 61 is identifiers - Phil
... 62 is same thing with Armin
... 63 is clear semantics, assigned to Bill, prob done before
next week's meeting
... 64 is discovery that Linda has done
close action-64
<trackbot> Closed action-64.
jtandy: 65 is spatial and temporal info, that's Chris
Frans: I think he volunteered for temporal
Linda: Yes, but Kerry twisted his arm
jtandy: Chris is on holiday this week.
... Those issues are so specific they won't be covered anywhere
else
... 66 is data exposed via APIs which is on Ed - because no one
else took it
... 67 is linking data which is Kerry
Frans: Sensor data is still missing
jtandy: I know Payam and Kerry are involved in the SSN stuff
... Maybe we can ping Payam... but he's on holiday too
Frans: He's a co-editor of the BP doc
jtandy: We are making progress. Given that we want to have an
FPWD by middle of October, time is of the essence
... I hope we'll have a structure, with the themes we'll be
covering, maybe on of them drawn out
phila: Suggests a frozen copy by Friday 16th, but not formal
publication until after TPAC
<Linda> +1
General agreement to this
<jtandy> +1
jtandy: I'd ask the chairs to promote that so people know what
to expect
<jtandy> bye
<jtandy> will type ...
