Not sure what changes since we last spoke. 20:09:13 ... Has some turtle examples 20:09:23 ... Interested in what Rob is doing with QB4ST 20:09:39 ... Also looking to add in some descriptions of our implementations 20:10:09 ... I want to read the BP, Time and SSN docs to see if there's stuff that should be references 20:10:15 q+ to ask about FPWD 20:10:42 billroberts: Rob isn't here today but I see he added an update to his wiki page over the weekend 20:11:00 ... and if you haven't seen it recently, see that. There are also egs in his GH repo 20:11:17 dmitrybrizhinev: We met him last week and we're clarifying what we're both doing. 20:11:25 billroberts: I was going to ask about that. 20:11:37 ... A couple of Qs. Is there help that you need? 20:11:44 q+ 20:11:44 ... Help that isn't already lined up? 20:11:54 dmitrybrizhinev: I don't have immediate questions right now 20:11:59 ... Will ask on the list. 20:12:07 billroberts: The offer is there. 20:12:24 ... Also, to ask at what point will it make sense for me and others to do a proper review? 20:12:33 ... i.e. nearly finished enough for detailed feedback? 20:12:49 roba has joined #sdwcov 20:12:52 dmitrybrizhinev: I expect about the new year should be a good time. 20:12:59 ack k 20:13:04 sorry i'm late.. 20:13:16 hi Rob - welcome, and no problem 20:13:34 kerry: I think we could ... provided we could fill in some of the ontology ... I would suggest feedback wold be valuable much sooner. 20:13:52 ... It's an example that covers a lot of what's going on in the group. It has SSN, Prov, OWL-Time 20:13:57 ... and hopefully some BPs as well. 20:14:16 ... So for that reason, I think it wojld benefit from more exposure before New Year. 20:14:30 kerry: I think we'll have enough for a FPWD before January. Maybe 1st week of December 20:14:38 dmitrybrizhinev: My exams are done by mid Nov 20:14:53 kerry: Australians can take a bit of a breather 20:15:06 ... I think aiming for a publication before Christmas makes sense all round. 20:15:29 billroberts: That sounds good to me. I think it's shaping up nicely, esp how other ontologies fit in. 20:15:35 ... I;bve added it to my To Do list 20:15:45 s/I;bve/I've/ 20:15:55 kerry: It needs the middleware explanation. 20:16:10 q? 20:16:25 kerry: A Q for Phil - the code etc. is all in GH, not in w3 space 20:16:40 ... and a related Q - the application. 20:17:02 ... On stability. This is a Note, but we can't maintain it beyond a year. 20:17:16 ack me 20:17:16 phila, you wanted to ask about FPWD 20:18:08 phila: dmitry - there's a lot of good work in here already. It's already pretty much complete enough for FWPD 20:18:20 ...apart from minor things like acknowledgements etc 20:18:21 q+ 20:18:37 ...If there are open issues, then add them in to the document 20:18:49 ...it's better to publish early 20:19:27 ...So seems feasible to get FWPD out in December. That doesn't mean it's finished, but gives people early visibility of what we are working on 20:20:06 ...and question to Kerry: is there an example web application that goes wtih this? 20:20:34 kerry: yes there is a web app that uses the example data (and much more) 20:21:21 phila: a publication in TR-space (which includes Notes) needs to have all supporting material in the same directory, which often means making multiple copies of shared resources 20:21:38 ...the document should include screenshots and a description, plus a link to the app itself 20:21:50 ...it's ok that the application won't be maintained indefinitely 20:22:06 ...but the document itself should be meaningful and readable 50 years from now 20:22:32 ...For example, our own BP document 20:22:35 -> https://www.w3.org/TR/2016/WD-sdw-bp-20160119/ FPWD of the BP doc 20:22:53 phila: see that this includes lots of links to open issues 20:23:08 phila: Scott, anything different for OGC? 20:23:16 ScottSimmons: same at OGC 20:23:28 q+ 20:23:32 ack roba 20:23:40 billroberts: I saw Rob on the queue 20:23:48 Topic: QB4ST 20:23:56 roba: I've bvegun working it into the Note format 20:24:13 ... I;ve revamped the ontology following a discussion with Kerry down in Canberra 20:24:21 ... I hope by the end of this week to have pushed something out for internal review 20:24:27 s/I;ve/I've/ 20:24:51 ... I'd like to aim for a FWPD at the same time as EO-QB as they cross reference each other 20:25:00 ... I need more eyes on the ontology 20:25:15 ... especially on the OWL entailment. 20:25:30 billroberts: So you reckon your stuff will be ready for some review by the WG? 20:25:41 ack k 20:25:57 kerry: Phil missed a question 20:26:07 .. Do yo want the code in a W3 GH? 20:29:04 billroberts: Anything more, Rob, to add? 20:29:40 roba: Not really. I've started the process of creating an LD resource to back this up. 20:29:48 ... There will be stuff to review. 20:30:02 ... Some is normative to the Note, some is more explanatory 20:30:04 * apologies all, I now get the great pleasure of visiting my dentist - coverages are far more interesting 20:30:04 q+ 20:30:24 ack phila 20:30:58 phila: documents that show cool things you did with the material from a W3C Note can probably go in your own space 20:31:10 ...W3 doesn't have anything better or more permanent than that 20:32:26 roba: The QB4ST Note is very short, it's just an ontology 20:32:32 q+ 20:32:58 https://www.w3.org/2015/spatial/wiki/RDF_Datacube_for_Coverages 20:36:03 phila: W3 can provide a namespace for the ontology, and hosting a test suite etc 20:36:14 ...running code and detailed examples can go best in your own space 20:36:23 ...stable building blocks fit well at W3C 20:37:13 phila: it's fine for it to be in teh opengeospatial space too 20:37:27 ...so can just leave it there 20:38:06 roba: this is a building block for EO-QB not a primer for it 20:39:13 ack k 20:39:14 ack k 20:39:52 kerry: Another idea... we tried to get this on last week's plenary agenda. They're not really aware of this work coming along so need some internal dissemination. 20:40:05 ... Maybe some of this could go into the spatial ontology that Josh is working on. 20:40:27 ... It's being used in the EO-QB as well. Maybe it gets wrapped into that doc. 20:41:04 Josh: Prob the best way for the spatial ontology is to update GeoSPARQL. 20:41:17 ... I created it as an update of GeoSPARQL as I needed to base other thinbgs on it 20:41:28 ... We needed a basic spatial ontology to base both the BPs and other efforts on 20:41:48 ... It;s a general spatial ontology. It's currently in my own namespace. I've discussed it with Scott. 20:41:52 q+ 20:42:15 ... I could put a Note together. It makes more sense to us for it to be an OGC doc referenced by the work here. 20:42:32 ... I'm open to otehr methods but that seems the consensus way. 20:42:56 kerry: If it goes that way, good. 20:43:15 roba: I had a chat with Josh. The first version had a dependency on Josh's interim version. 20:43:52 ... I took a leaf from the SSN modularisation discussion. For the very few concepts from there, I've calle edthem out and created a local place holder in the QB4ST namespace but it says oit's meant to be aloigned with the general spatial ontology 20:44:03 q+ to talk about IANA 20:44:28 roba: We don't wante a hard dependency on something whose status is currently unknown. 20:44:50 Josh: I think its largely a timing problem. Ideally, QB4ST will import GeoSP2 20:45:13 roba: I'm happy tpo take guidance from the community of course. 20:45:57 Josh: SO one of the issues it trying to help other people do the right thing. The difficulty with using the basic Geo is that there are several incompatibilities with the OGC/ISO methods 20:46:15 ... We can map it, but it would be good not to start with that. 20:46:22 ... Start with something broader. 20:46:50 ... We can have a basic but fairly complete spatial ontology. Multiple and identifiable geometries, CRSs etc. 20:47:02 ... I don't think we have time for a CRS ontology. 20:47:32 ... There's an effort by Natalie at IGN to do that. Making good on the idea that the application of a lot of these depends on getting hte CRS right. 20:47:45 billroberts: Is there already something that we can see? 20:47:58 Josh: The OWl and Turtle files are available 20:48:44 joshlieberman has joined #sdwcov 20:48:56 http://geosemweb.org/sdwgeo 20:49:29 q- 20:49:39 joshlieberman: I started out having this in Web Protoge but I gave up on that in the end. I'm working on the documentation that isn't in the ontology itself 20:50:16 ack me 20:50:16 phila, you wanted to talk about IANA 20:50:17 ack phil 20:52:10 -> http://www.iana.org/assignments/link-relations/link-relations.xhtml IANA Link registry 20:52:25 qb4st imports OWL-Time (updates) now - but OWL expressivity for temporal being possibly a "coded" dimension as well is going to take some thought.. 20:55:04 [Discussion about getting spatial and temporal relations into the Link Registry] 20:55:15 Topic: Coverage JSON 20:55:43 billroberts: Not much to report ad Jon is working on finalising his project. But last time I spoke to him he thought end November was a good time line to have that out. 20:56:00 ... No real progress in last 2 weeks 20:56:28 phila: So we're looking at getting the 3 docs out together before Christmas 20:56:34 Topic: AOB? 20:57:04 roba: Just one more thing... I'd be happy to take other contributors on board for QBST 20:57:24 billroberts: Things generally go better as a team effort. 20:57:48 kerry: I'd like to volunteer but I daren't. I can try but don't bank on it. 20:58:15 billroberts: Given that people don't always read these minutes in detail, might be worth putting a call out to the mailing list. 20:58:29 roba: I'll get the first cut of the Note in the right format. 20:59:19 RRSAgent, draft minutes 20:59:19 I have made the request to generate http://www.w3.org/2016/10/26-sdwcov-minutes.html phila 20:59:27 thankyou bye! 20:59:37 bye 20:59:42 RRSAgent, draft minutes 20:59:42 I have made the request to generate http://www.w3.org/2016/10/26-sdwcov-minutes.html phila
