13:05:15 <phila> RRSAgent, draft minutes
13:05:15 <RRSAgent> I have made the request to generate http://www.w3.org/2016/08/24-sdwcov-minutes.html phila
13:05:18 <billroberts> https://www.w3.org/2015/spatial/wiki/Meetings:Coverage-Telecon20160824
13:06:51 <phila> billroberts: Not expecting Jon and Maik to be at TPAC but likely to participate by remote
13:07:18 <phila> billroberts: By the end of the meeting, we shoujld have reasonably complete drafts of our key outputs
13:07:35 <phila> ... Expected to be a Note/Discussion Doc on Coverage JSON and on the use of RDF QB in represetning Coverages
13:07:44 <phila> ... That might change but it seems right
13:07:56 <phila> ... So before the meeting we should have reasonably complete drafts to talk about
13:08:18 <phila> ... So does the work that ANU has been doing make sense as a separate doc?
13:08:38 <phila> ... 'complete' means that issues are recognised, noit that the doc is complete
13:08:59 <phila> ... So we could hopefully then have FPWD staight after TPAC
13:09:19 <phila> billroberts: So my first question is... is the current wiki page for attending TPAC up to date?
13:09:30 <billroberts> https://www.w3.org/2015/spatial/wiki/Attending_F2F4
13:09:37 <phila> billroberts: That's the current list
13:10:18 <phila> billroberts: So no one on the call other than Phil and I will be there
13:10:51 <phila> billroberts: If not attending in  person, can people join remotely?
13:11:11 <phila> phila: Note that Lisbon time is the same as UK where it is currently 14:11
13:11:18 <phila> phila: (and 31 degrees)
13:11:29 <phila> chrisL: I'll be travelling to Helsinki that day
13:12:28 <phila> Duo: The ANU team will probably be in class
13:12:40 <phila> q+
13:12:47 <phila> billroberts: It depends on the scheduling I guess
13:12:58 <phila> q-
13:13:18 <phila> billroberts: SO Kerry suggested Monday afternoon, 14:00 - 17:00 local time
13:13:57 <phila> phila: Can we shift it to a time that willwork for ANU?
13:14:07 <ChrisLittle_> ChrisLittle_ has joined #SDWcov
13:14:24 <ChrisLittle_> Present+ ChrisLittle
13:14:33 <ScottSimmons> q+
13:14:46 <phila> billroberts: So if Sam and Duo can check your schedules please for 19/20 Sept
13:14:52 <phila> ack ScottSimmons
13:15:22 <phila> ScottSimmons: That Monday is also the opening plenary of the TC where Jon Blower is presenting at, I think 15:30 Lisbon time
13:15:43 <phila> billroberts: So more reason to move Coverages away from Monday afternoon
13:15:55 <phila> ScottSimmons: Our coverages grpoups at PGC don't meet until Thursday 22nd
13:16:02 <phila> s/PGC/OGC/
13:16:20 <phila> billroberts: So I'll go back to Kerry on the scheduling
13:16:42 <phila> Topic: What will we discuss at TPAC
13:16:54 <phila> billroberts: On the CJ stuff, we need input from its authors of course.
13:17:09 <phila> ... One thing ...with the CJ, they havea some well developed docs
13:17:19 <phila> ... in terms of spec and tutorial material
13:17:28 <phila> ... what makes a sensible contact of a NOTE?
13:17:44 <phila> ... A Primer? Explanation of how to start
13:21:19 <phila> phila: Rambles on about ideal (spec, primer and test suite) and what Jon and Maik have time and inclination to do.
13:21:32 <phila> ... Being published by W3C and OGC carries some weight so it needs to be right
13:21:37 <phila> ScottSimmons: +1 from OGC
13:22:02 <phila> billroberts: Whether it's one or multiple docs seems achievable to me
13:22:18 <phila> ... Sounds like I need to talk to Joj and Mail about what they can realistically do
13:22:22 <phila> s/Joj/Jon/
13:22:56 <phila> billroberts: Having looked at the UCR, I think the CJ spec needs more on identifiers. There's some stuff in the GH repo about that
13:23:18 <phila> billroberts: I'll see if Jon is able to put a bit of prep into that.
13:23:37 <phila> billroberts: The otehr part of what we need to cover at the meeting is the Note/DP about QB work
13:23:46 <phila> ... That's where the people on the call now are more involved.
13:24:37 <phila> Duo: Sam and Dimitri might have more to say
13:25:04 <ChrisLittle> ChrisLittle has joined #Sdwcov
13:25:52 <phila> billroberts: It would be great if you can start filling that wiki page out, taking us from initial ideas to something closer to a doc. All text doesn't need to be finished but we need to know what the doc willlook like and what the open issues are.
13:26:17 <phila> roba: I put out a strawman as requested with ideas about what a set of baseline dimensions and measures mighjt need to look like
13:26:30 <phila> ... Had a quick discussion with DImitri and Sam but yet to ghet any detailed feedback
13:26:57 <phila> roba: I can take that work a bit further forward. I'm concerned that it needs more eyeballs
13:27:29 <ChrisLittle> Q+
13:27:30 <billroberts> Rob's note: https://www.w3.org/2015/spatial/wiki/RDF_Datacube_for_Coverages
13:27:33 <phila> ... I've just been reviewing the UCR from the SSN perspective, looking at where sensors were producing coverages and I do feel that the current set of deliverables necessarily address a lot of the requiremsnts in terms of descriptive metadata
13:27:38 <phila> ... which QB is better at
13:28:20 <phila> ... One thing I did put in the review - capturing CRS and UoM, precision and accuaracy - and they're common to things other than coverages
13:28:38 <phila> .. SO it's up the WG to see which requirements we're going to address.
13:28:49 <phila> ... I don't want to suggest I can do it all by myself without at least feedback.
13:29:17 <phila> billroberts: I trhink that is useful work and I'd like to see it as part of our outputs
13:29:22 <billroberts> ack chris
13:29:32 <phila> ChrisLittle: Can I encourage Rob - it's on my list of things to do now I'm back from holiday.
13:29:46 <phila> roba: So if people are rebooting - look at the UC review
13:30:06 <phila> ... Lots of cross refs missing for SSN but the coverages stuff seems in reasonable shape but feedback would be very welcome.
13:30:30 <ChrisLittle> Q-
13:30:41 <phila> roba: Always happy to see a plan B from elsewhere
13:31:09 <phila> billroberts: We should be able to bring together enough people to get the experience and perspective. SSN has similar issues
13:31:20 <phila> ... I'm pretty familiar with QB for stats
13:31:37 <phila> roba: That sounds encouraging so I'm happy to do what I can to pull things together and keep this to a small scope.
13:31:57 <phila> ... My feeling is that it's likely to be a separate Note or an extension to anotehr doc
13:32:08 <phila> billroberts: OK, so there's an objective to head for the 19 of Sept
13:32:31 <phila> roba: Always happy to have extra sessions with screen sharing etc.
13:32:36 <phila> q+
13:33:04 <ChrisLittle> As long as discussions appear on public channel
13:33:35 <phila> billroberts: People can easily work on stuff outside the meetings,
13:33:38 <phila> q-
13:33:56 <phila> roba: I'll leave it to Bill and Chris to sort that out then
13:34:08 <phila> .. obviously the ANU time zone is easier.
13:34:23 <phila> billroberts: So I'll pull the relevant parts together so we know what to talk about at TPAC
13:34:57 <phila> TOPIC: Metadata separation
13:35:25 <phila> billroberts: You, Rob, thought that some of our discussions were tending towards merging data and metadata - you were going to review the UCs in this regard?
13:35:54 <phila> roba: I think it is covered. I recommended some fairly vague wording is made a bit stronger and more testable
13:36:09 <phila> ... the user needs to be able to determine what the CRS is, etc.
13:36:19 <phila> ... There are some explicit notes in my review on this.
13:36:34 <phila> ... Given a piece of data, it should be possible to find the metadata, for example
13:36:49 <phila> ... I guess this is why I'm recommending people start with that review
13:37:02 <phila> billroberts: Is that review on the mailing list?
13:37:12 <phila> roba: I sent it this morning nad it bounced
13:37:18 <phila> ... So I sent it again
13:37:47 <billroberts> https://lists.w3.org/Archives/Public/public-sdw-wg/2016Aug/0172.html
13:37:55 <phila> -> http://lists.w3.org/Archives/Public/public-sdw-wg/2016Aug/0172.html Rob's UC review
13:38:51 <phila> roba: I think this maybe comes back to what we, as a broader WG, need to do in terms of providing some testability around what we're suggesting. Hand waving about what you ought to do really needs to be better
13:39:25 <phila> billroberts: It's a tricky one. In some cases, those reqs have been written to be implementation-neutral. Some times we've been trying to worry about spaecially spatial etc.
13:39:43 <phila> .. DWBP talks about metadata and prov - maybe we don't want to be too specific in SDW
13:39:51 <phila> RRSAgent, draft minutes
13:39:51 <RRSAgent> I have made the request to generate http://www.w3.org/2016/08/24-sdwcov-minutes.html phila
13:40:01 <phila> billroberts: Not sure what the thinking was around that...
13:40:50 <phila> roba: I think people in the specific subgroups need to be clear how people can meaningfully test that requirements have been met.
13:41:22 <phila> billroberts: On scheduling - I'm on leave from the end of this week for 2 weeks.
13:41:31 <phila> ...So I'll try and get a few things done between now and then.
13:41:47 <phila> ... After I'm back, I have little time before we head for Lisbon
13:41:58 <phila> ... SO a practical question - do we want a call in 2 weeks without me?
13:42:12 <phila> ... I can get in touch with Kerry and see if she can coordinate and chair that one.
13:42:25 <phila> ... It's only 3.5 weeks to Lisbon so I'd like to keeop things going.
13:42:35 <phila> s/keeop/keep/
13:42:49 <phila> billroberts: I dare say Kerry will take that on if she can.
13:42:59 <phila> roba: I have a lot on my plate ahead of the TC
13:43:24 <phila> billroberts: SO we have lots of open questions...
13:43:28 <phila> Topic: AOB?
13:43:35 <phila> s/SO/So/g
13:43:45 <phila> s/CJ/CoverageJson/g
13:44:06 <phila> roba: Maybe a more general question... what is the status of the extension of the WG timeline?
13:46:52 <phila> phila: Talks a bit about June 2017
13:47:06 <phila> billroberts: OK, then thanks everyone, we'll stop there.
13:47:09 <ChrisLittle> Bye and good holiday Bill
13:47:19 <billroberts> bye all
