20:07:51 <tidoust> Topic: Sub-groups and their work plans
20:08:09 <tidoust> jtandy: After last meeting last month, we discussed with Linda, Francois, Scott.
20:08:21 <tidoust> ... We have a Statistics Data on the Web group led by Bill.
20:08:23 <tidoust> Bill: Right.
20:08:55 <tidoust> ... Liaison with Stats CG goes well. On the call last time.
20:08:58 <josephabhayaratna> josephabhayaratna has joined #sdw
20:09:09 <tidoust> jtandy: SSN Primer group led by Armin who is not around, so cannot confirm.
20:09:33 <tidoust> ... SSN & Observation doc, not ready yet, so not moving ahead for now.
20:09:46 <tidoust> ... Spatial data on the Web BP group led by Michael, first call an hour ago.
20:10:13 <tidoust> ... The errata for the specs published by the WG, we're not going to process them in sub groups but within the whole group.
20:11:00 <tidoust> ... QB4ST, I have an action to check with roba, we can talk about that later on.
20:11:19 <Linda> q+
20:11:25 <tidoust> ... Also EO-QB, so far, we haven't had any contacts with the previous editors.
20:12:14 <tidoust> ... Effectively, you can organize your own work, and then we'll try to update on progress from everyone to see what support you might need from the group.
20:12:16 <tidoust> ack Linda
20:12:37 <ChrisLittle> q+
20:12:40 <tidoust> Linda: I did have some email contact with Kerry. She did say that she was planning to join this IG but haven't done so yet.
20:12:43 <tidoust> ack ChrisLittle
20:13:21 <tidoust> ChrisLittle: One of the issues I want to discuss is a follow-up in Time Ontology in OWL. Interested in non-Gregorian calendar such as the 365 calendar.
20:13:28 <tidoust> ... It's not quite errata for the Time Ontology.
20:13:40 <roba> q+
20:13:40 <tidoust> ... I'm certainly going to discuss it next week in OGC.
20:13:48 <tidoust> ... Would this group have any views?
20:13:56 <tidoust> ack roba
20:14:13 <tidoust> roba: That sort of example of using other calendars would be a use case for QB4ST.
20:14:37 <tidoust> ... It's certainly of interest and make a useful test case.
20:14:48 <jtandy> q?
20:15:21 <tidoust> jtandy: In terms of publishing stuff, we can create Notes without problem.
20:15:46 <tidoust> ... To push it as a REC, we need to go through a more formalized process.
20:16:47 <tidoust> Francois: I confirm we need a WG to publish as a REC. That's doable!
20:17:38 <jtandy> q?
20:17:57 <jtandy> https://www.w3.org/2017/sdwig/
20:17:59 <tidoust> ... The Spatial Data on the Web WG is in passive mode. We'd need a new group (possibly with the same name, but a new one reviewed by the Advisory Committee)
20:18:15 <tidoust> jtandy: We can start the incubation in this IG.
20:18:39 <tidoust> Topic: Tools and Web-pages for SDW-IG
20:18:51 <tidoust> jtandy: Francois is maintaining the home page manually for now.
20:19:07 <MichaelGordon> +1
20:19:12 <ChrisLittle> +1 GitHub and markdown
20:19:13 <tidoust> ... What we're proposing with Linda is that we do as much work as we can in the GitHub repository, and use Markdown
20:19:29 <roba> q+
20:19:37 <jtandy> q?
20:19:42 <tidoust> ... I have done it before in another project. I have an action to kick things off.
20:19:45 <tidoust> ack roba
20:19:49 <AndreaPerego> AndreaPerego has joined #sdw
20:20:10 <tidoust> roba: The ReSpec system has a way of handling bibliography and links. Is there a middle ground?
20:20:19 <AndreaPerego_> AndreaPerego_ has joined #sdw
20:20:50 <tidoust> ... using Markdown?
20:21:06 <tidoust> Francois: ReSpec supports Markdown, I think, so you can benefit from these in Markdown too.
20:21:08 <MichaelGordon> q+
20:21:17 <tidoust> ... I need to dig it up, will share links.
20:21:20 <jtandy> q?
20:21:42 <tidoust> Bill: I used Markdown for the Stats on the web BP. It works fine.
20:21:43 <tidoust> ack MichaelGordon
20:22:29 <tidoust> MichaelGordon: During the SDW BP maintenance call, we had a similar discussion. Planning to use Markdown to share Comm plan.
20:23:14 <tidoust> ... I haven't used ReSpec at all. Goal is to make sure that people are familiar with tools. Suggests listing some notes.
20:23:48 <tidoust> jtandy: There's a lot of material available already. For ReSpec, one thing that I found useful was working with someone who was already familiar with ReSpec.
20:24:02 <tidoust> ... We can write a little Primer to guide our users on tools we're using.
20:24:52 <tidoust> jtandy: What about the "harmonizing WG home pages" activity?
20:25:00 <tidoust> Francois: No news for now. Will check and report.
20:25:03 <jtandy> q?
20:25:15 <tidoust> Topic: Update on MapML
20:25:25 <AndreaPerego> present+ AndreaPerego
20:25:41 <tidoust> PeterRushforth: I prepared a presentation with audio and video and wonder if it is possible to show that over WebEx
20:27:41 <tidoust> [Playing with WebEx]
20:28:46 <tidoust> PeterRushforth: We started the Map for HTML CG in 2014 at the Linking Spatial Data meetup in London
20:29:01 <tidoust> ... I've been prototyping the concepts we've talked about in that meeting since then.
20:29:08 <tidoust> ... I'd like to give you a demo today.
20:29:46 <jtandy> q?
20:30:35 <tidoust> -> https://www.w3.org/community/maps4html/ Maps for HTML CG
20:31:10 <tidoust> PeterRushforth: Maps for HTML is a markup language. Standardization of maps in HTML is an attainable goal, that's what we'd like to demonstrate.
20:31:47 <tidoust> ... Location plays a role in every decision that we make today and into the future.
20:32:02 <tidoust> ... And yet, integration of spatial data is not done.
20:32:11 <tidoust> ... There's no go to standards for Web mapping.
20:32:17 <tidoust> ... Where should the beginners start?
20:32:48 <tidoust> ... The Web is for everyone said Tim Berners Lee. If it's not easy to make a map, we're not doing good.
20:33:05 <tidoust> ... Making Web mapping the exclusive domain of seasoned and specialists
20:33:09 <tidoust> ... is restrictive.
20:33:14 <tidoust> ... We need to step back.
20:33:29 <tidoust> ... How to have newcomers start their journey through GIS?
20:33:45 <tidoust> ... The Web platform is the ubiquitous platform that we need.
20:34:06 <tidoust> ... The Maps for HTML CG is to extend HTML to include maps so that people can use the tools everyone has to play with maps.
20:34:41 <tidoust> ... [showing a demo of a maps services repository in Canada]
20:35:30 <tidoust> ... Searchable and indexable repository. Supports maps in more than one projection. That's a concept in MapML to include other projections.
20:35:56 <tidoust> ... The Canadian geospatial platform provides many map services in Lambert Conformal Conic form.
20:36:21 <tidoust> ... The Canada base map. Here, you're seeing one rendered with an HTML Custom Element.
20:36:30 <tidoust> ... Works like a leaflet.
20:36:43 <tidoust> ... And in fact I used Leaflet for this.
20:36:59 <tidoust> ... See the <map> tag element.
20:37:12 <tidoust> ... Attributes used to extend the base element
20:38:04 <tidoust> ... [using view source to show the rendering of the map element]
20:38:08 <ChrisLittle> ChrisLittle has joined #sdw
20:38:26 <tidoust> ... MapML is modeled from HTML. The idea is that it represents a map element that supports stacking of layers.
20:38:49 <tidoust> ... The <extent> element is based on the form element but supports inputs that are specific to maps.
20:39:20 <tidoust> ... The <tile> element implements the OGC aspect
20:39:58 <tidoust> ... Cubewerx implements MapML. They implemented the gotopo layer for instance.
20:40:30 <tidoust> ... Finally, just to close the loop on data types that are available. We have a vector dataset here.
20:41:21 <tidoust> ... It behaves like how you would expect them to behave. Map balloons for different features. Features would by stylable using CSS and vanilla Web technologies.

20:43:16 <jtandy> q+
20:43:46 <tidoust> ChrisLittle: OGC mailing-list discussion about stylesheets. Rob and Jerome something, comes out of an ad-hoc meeting we had somewhere. Trying to ressussissate "SLDAC"
20:43:56 <roba> q+
20:44:05 <tidoust> ... CSS deemed too complex for the hierarchy in maps.
20:44:22 <tidoust> ... But the open source community reacted to that because it was felt too complex
20:44:38 <roba> q-
20:44:53 <tidoust> jtandy: Can I ask you two to have a discussion about that on the mailing-list?
20:44:58 <tidoust> ChrisLittle: Sure!
20:45:07 <tidoust> jtandy: Anything you need from the IG, Peter?
20:45:18 <roba> what about topology-centric maps? where navigation is by topological relationships rather than coordinates?
20:45:24 <Linda> s/SLDAC/SLDSE
20:45:25 <tidoust> PeterRushforth: What do you think about the idea of standardizing maps in HTML?
20:45:50 <jtandy> q?
20:45:51 <tidoust> jtandy: Why don't you share the presentation with voice-over on the mailing-list and start the discussion there?
20:45:57 <jtandy> q-
20:46:57 <tidoust> Topic: Updates from each active work stream
20:47:46 <tidoust> billroberts: Stats on the Web group. We had a call last week. 7 people roughly. Intro call. Focusing on examples. Jo volunteered to present at the geosemantic meeting of the OGC meeting next week.
20:48:00 <tidoust> ... I'm summarizing what we're doing in that group for the OGC.
20:48:40 <tidoust> jtandy: Are you clear what your aims are for the group?
20:48:53 <tidoust> billroberts: Yes. Same as the SDW BP doc, but for Stats!
20:49:08 <tidoust> jtandy: Anything you need from the group, chairs and Francois?
20:49:20 <tidoust> billroberts: Nothing that I already got.
20:49:33 <tidoust> jtandy: Michael, what are your aims? Progress? Need from the group?
20:50:13 <tidoust> Michael: BP maintenance sub-group. Adoption and evangelization of the Best Practices to encourage knowledge of them.
20:50:26 <tidoust> ... And then to look at the gaps that have already been called out in the document.
20:50:47 <tidoust> ... I think certainly that's where we want to see feedback
20:50:57 <tidoust> ... Adoption of the best practices, first area.
20:51:05 <tidoust> ... In terms of progress, we just had our first call.
20:51:36 <tidoust> ... The main action point is for me to add details of some of the initial ideas to GitHub and provide a bit of structure, to be shared with the group in the next couple of weeks.
20:52:21 <tidoust> ... In terms of requirements, if people can evangelize the work in the meetings they attend, that's good, always useful!
20:52:22 <jtandy> q?
20:52:33 <jtandy> q?
20:52:50 <tidoust> jtandy: Moving to Rob.
20:53:36 <tidoust> roba: QB4ST update. To take it forward needs more work examples and implementation experience. If anybody is doing that, I will support that in terms of versioning and moving forward.
20:53:45 <tidoust> ... I'm having discussions with DGGS.
20:54:08 <tidoust> ... That's another set of use cases that would provide input.
20:54:20 <tidoust> ... Open work depending on what people are interested in.
20:54:39 <tidoust> jtandy: You can tune the Note based on implementation experience.
20:54:53 <tidoust> roba: Yes, or take it to the REC track if there is interest.
20:55:21 <tidoust> jtandy: Same as for the time ontology, we need a WG to take things to REC. Just be aware of that.
20:55:22 <jtandy> q?
20:55:35 <tidoust> roba: Yes. It comes down to people wanting to implement things.
20:55:50 <tidoust> jtandy: Exactly. That's what the Advisory Committee at W3C will look at.
20:56:04 <roba> q+
20:56:12 <tidoust> ... Armin and Jano are not around to talk about SSN and Moving Objects. No one for EO-QB
20:56:15 <tidoust> ack roba
20:56:49 <tidoust> roba: EO-QB is really a best practices primer, including how to use QB4ST. Whether it needs to move forward as an enabler is an open question.
20:57:33 <tidoust> jtandy: If it does awakens, and is BP, it may fall within Michael's job.
20:57:50 <josephabhayaratna> Gotta run all. Until next time :)
20:57:58 <Linda> Francois: nothing on the Time ontology as far as errata
20:58:09 <Linda> ... in the SSN spec a few broken links etc
20:58:27 <Linda> ... strict policy for updating recs
20:58:42 <Linda> ... but fixing links is allowed
20:58:50 <jtandy> q?
20:58:51 <Linda> ... will post on the mailing list
20:59:29 <Linda> ... encourages people to look at the rec doc now because we will not do this update process many times
21:00:22 <roba> can respec hav a ttl-lint function :-)
21:00:47 <MichaelGordon> +1
21:00:48 <Linda> +1
21:00:52 <roba> +1
21:00:55 <tidoust> jtandy: Thank you. Looking at the time, I suggest we talk about F2F options on the mailing-list.
21:01:10 <ChrisLittle> +1
21:01:10 <tidoust> ... TPAC updates?
21:01:24 <tidoust> Linda: Not much to say, will raise on the mailing-list.
21:01:40 <tidoust> jtandy: Same thing for accessibility on the maps.
21:01:44 <jtandy> q?
21:01:45 <tidoust> Linda: On the mailing-list, it's good.
21:01:53 <tidoust> Topic: Next meeting
21:02:29 <tidoust> jtandy: In a month, it will be pretty much Christmas and for many of us a difficult time for us to be available. When would people want to meet again?
21:02:30 <roba> unavailble till the new year, then flexible
21:02:39 <billroberts> q+
21:03:12 <jtandy> q?
21:03:13 <tidoust> MichaelGordon: I'm only available in the next couple of weeks, typically, then travel, Christmas and so on.
21:03:17 <tidoust> ack billroberts
21:03:37 <tidoust> billroberts: Just a suggestion that we have a 5 week gap until the next meeting.
21:03:49 <tidoust> ... We could start fresh and enthusiastic on the 3rd of January.
21:03:57 <Linda> +1
21:04:01 <tidoust> jtandy: Any objection?
21:04:23 <PeterRushforth> +1
21:04:43 <tidoust> ChrisLittle: [discussing timing of alternating plenary and group calls]
21:05:03 <jtandy> q?
21:05:05 <tidoust> jtandy: OK, January seems a good option.
21:06:01 <PeterRushforth> Thanks!!
21:06:06 <tidoust> ... It would be good to have an update about things that happened in New Zealand next time.
