topic: patent call https://www.w3.org/2015/spatial/wiki/Patent_Call
20:07:09 [tidoust]
[Armin goes through the usual patent call notice]
20:08:00 [tidoust]
Armin: Light agenda today. Status update, and then uptake of the SOSA work in schema.org.
20:08:20 [tidoust]
... Dan Brickley would like some explicit indication from the group that the group is OK.
20:08:42 [ahaller2_]
topic: Coverage sub-group progress
20:08:59 [tidoust]
Bill: 3 deliverables that we've been working on. They are all pretty much in the final state.
20:09:11 [tidoust]
... QB4ST, I made a couple of minor edits to that today.
20:09:18 [tidoust]
... A couple of minor issues, on Rob's plate.
20:09:29 [tidoust]
... I'm sure we can address them by tomorrow.
20:09:43 [tidoust]
... The EOQB is now I think complete.
20:10:05 [tidoust]
... The CoverageJSON document, we've done quite a lot of work in the last couple of weeks.
20:10:14 [tidoust]
... Close to being finalized. One remaining issue from Jon.
20:10:42 [tidoust]
... Jon wrote a short section that discusses relation between CoverageJSON and OGC Time series ML standard.
20:10:56 [tidoust]
... Who would you think would be the right person to ask to review that part?
20:11:08 [ahaller2_]
q?
20:11:20 [tidoust]
Armin: That's a good question. Simon does not seem online, he's the one I would have thought about.
20:11:33 [ScottSimmons]

Bill: I'm happy to approach him through the mailing-list.

q?
20:12:08 [tidoust]
ScottSimmons: I recommend talking to Chris Little. Time-centric guy and expert in coverages as well.
20:12:19 [tidoust]
Bill: OK, very useful tip, thanks. I'll email him tomorrow.
20:12:47 [tidoust]
... Assuming that Chris is willing to do that, then there is a little bit of work remaining to do on CoverageJSON to take it to a final state.
20:13:11 [tidoust]
... What do we then need to do to each of these documents to formalize the publishing of the final version of these?
20:13:15 [ahaller2_]
q?
20:15:21 [tidoust]
Francois: Essentially, I need a WG resolution for each of these docs that states that the group is OK with publication as final WG Note, and then I can proceed.
20:15:33 [tidoust]
... Publication can happen last week of June.
20:15:46 [tidoust]
... Resolution should be through a Call for Consensus on the mailing-list.

q?
20:17:44 [ahaller2_]
topic: time subgroup
20:17:46 [tidoust]
Francois: I'll get in touch with Jeremy and Linda about the doc. Same thing, publication as final WG Note would need a WG resolution.
20:18:06 [tidoust]
Armin: Simon is not around.
20:19:39 [tidoust]
Francois: Published as a CR on W3C side. Needs to stay in CR until beginning of July. Then it all depends on the completion of the implementation report.
20:19:57 [ahaller2_]
q?
20:20:04 [tidoust]
Scott: On the OGC side, we're working on the process to follow. That should work out just well in the end.
20:20:09 [ahaller2_]
topic: SSN subgroup
20:20:47 [tidoust]
Armin: We'll have another 2 calls. We're still adding examples. Interesting discussions with people implementation IoT actuation through REST APIs.
20:21:09 [tidoust]
... Some pending PR on our side to add actuation examples, to query the state, etc.
20:21:19 [tidoust]
... Otherwise, no change to the document, apart from updating figures.
20:21:45 [tidoust]
... We had a couple of discussions around a couple of axioms that could pose some problems.
20:22:00 [tidoust]
... We had some discussions among editors, but figured out this was not an issue.
20:22:17 [tidoust]
... Only one inverse property axiom that needs to be deleted, on-going PR to do that.
20:22:56 [tidoust]
... That would be a change to the ontology, but to remove a property, not to cause some unwanted entailment.
20:23:13 [tidoust]
... That's the only thing which changed in the normative part.
20:23:50 [tidoust]
... The i18n group is reviewing the doc, which prevents publication as CR
20:23:52 [ahaller2_]
q?
20:26:09 [tidoust]
Francois: Will check i18n review status. We should have done that before. No big deal about the minor normative change provided the group is aware of it.
20:26:17 [ahaller2_]

20:26:26 [tidoust]
Armin: I'll warn the group. We're also making progress on recording implementation evidence.
20:26:52 [tidoust]
... We may still have issues around system capabilities. Identified as feature at risk.
20:27:10 [ahaller2_]
q?
20:27:26 [tidoust]
... We probably won't have implementation evidence for that, but that should not be a problem given the exit criteria and at risk features.

topic: Vote on Endorsement of SOSA for Schema.org adoption
20:30:53 [tidoust]
Francois: [reminds everyone of end of June deadline and need to show as complete an implementation report by then]
20:31:41 [tidoust]
Armin: Goal is to take SOSA core, lightweight ontology in the SSN subgroup, which was always intended to be schema.org friendly, and adopt it in schema.org.
20:32:08 [tidoust]
... Dan Brickely wants us as a Working Group to endorse him to do that (due to previous frictions in similar cases)
20:32:08 [KJanowic]
q+
20:32:16 [tidoust]
... Within the SSN subgroup, we have no issue with that.
20:32:26 [ahaller2_]
ack KJanowic
20:32:27 [tidoust]
... But we wanted to raise that in the plenary.
20:33:21 [tidoust]
KJanowic: If I understand correctly the tricky part here is that we're working on a W3C/OGC standard, and schema.org is de facto standards, and it would be odd to see the standard work "forked".
20:33:40 [tidoust]
... What's important to point out is that this is not a fork, but an endorsement of our work.

Bill: I support the idea. If we have two copies of more or less the same thing, risk of having things diverge may exist, but I think it's minimal in this case.
20:34:52 [tidoust]
... It's a very positive thing.
20:35:07 [tidoust]
... I would give my support to schema.org endorsing this work.
20:35:14 [tidoust]
... It's the best thing for sensing data.
20:35:14 [KJanowic]
The point was that we should give Dan the endorsement and work with him to ensure that this is not a fork. SOSA was developed with schema.org in mind
20:35:42 [KJanowic]
q+
20:36:18 [tidoust]
Francois: Do we know already if schema.org is going to make changes to the ontology?
20:36:22 [ahaller2_]

ack KJanowic
20:36:37 [tidoust]
Armin: That's still to be discussed. We can't anticipate what things they may want to drop or extend.
20:37:17 [tidoust]
KJanowic: I think the email was triggered by DCAT people not being happy about the adoption in SOSA.
20:37:28 [tidoust]
... For the moment, we should just push for that adoption.
20:37:30 [ahaller2_]
q?
20:37:52 [tidoust]
Armin: Taking up SOSA would also be implementation evidence.
20:37:55 [KJanowic]
s/adoption in SOSA/ forking in schema.org
20:37:58 [tidoust]
... Something very useful
20:38:09 [ahaller2_]
q?
20:38:31 [KJanowic]
schema.org is a great chance for SOSA (and the other way around)
20:38:53 [KJanowic]
q+
20:39:39 [tidoust]
Francois: Just wondering whether changes made by schema.org could mean that we haven't done our job properly with SOSA for instance.
20:39:59 [tidoust]
Armin: That's basically how things work with ontologies. I don't think this would be an issue.
20:40:12 [tidoust]
... Changes would not be an indication that we did something wrong.
20:40:14 [ahaller2_]
ack KJanowic
20:40:43 [tidoust]
KJanowic: Let me just add that I'm sure they won't use everything directly, because they have a different audience, and need to be conservative.
20:41:04 [tidoust]
... Also, for consistency with their naming conventions, they may come up with different names. That's perfectly fine as well.
20:41:24 [tidoust]
... That's why I think it's important to work with Dan.
20:41:34 [ahaller2_]
q?
20:41:44 [tidoust]
... We should be on the train to be able to influence that work.
20:42:14 [tidoust]
