13:23:14 [McCool]
mm: I have marked existing WoT meetings as yellow conflicts during plugfest week
13:23:25 [McCool]
... although we might cancel them, to discuss
13:23:33 [McCool]
dape: was there an email for the doodles?
13:23:39 [McCool]
kaz: not yet, I will do
13:23:42 [dape]
ack dape
13:23:47 [kaz]
action: kaz to send an announcement on the doodle
13:24:16 [McCool]
sk: proposal for actual vF2F, propose some times from March 15 - 26.
13:24:20 [McCool]
q+
13:24:58 [McCool]
mm: I propose that we try to schedule a total of 15h over those two weeks
13:25:11 [McCool]
... let's use the doodle to figure out the best slots to use
13:25:50 [McCool]
sk: note also that these two weeks are when the daylight savings time is changing, so be careful when checking times
13:27:03 [McCool]
mm: once we decide on times I can send out calendar invites which will hopefully show the times correctly in everyone's local timezone
13:27:10 [McCool]
topic: Liaisons

present+ Michael_Koster
13:28:13 [McCool]
mm: have not heard about any plans for a T2TRG meeting
13:28:31 [McCool]
... but normally they do have one prior to IETF, which is in five weeks
13:28:45 [McCool]
mk: will contact Ari and see
13:28:50 [kaz]
rrsagent, make log public

rrsagent, draft minutes

I have made the request to generate https://www.w3.org/2021/01/20-wot-minutes.html kaz
13:29:39 [McCool]
mm: I think a joint call would be helpful to get updates on IETF activities, ASDF, etc...
13:31:05 [zkis]

13:31:55 [dsr_]
dsr_ has joined #wot
13:33:19 [McCool]
mm: for IETF, need to go through calendar and see what's scheduled
13:33:28 [McCool]
... some relevant actitives around JSON, etc.
13:33:45 [McCool]
sk: for OPC-UA, we have been talking to validation group
13:34:06 [McCool]
... but it seems it was not quite the right group for a OPC-UA binding for WoT
13:34:36 [McCool]
... so since there does not seem to be an appropriate group, proposing to make a "companion group"
13:34:44 [McCool]
... to create a binding
13:35:10 [McCool]
sk: so now propose working on a joint charter; also need to understand what companies would be interested

q+
13:37:01 [McCool]
sk: need to define mostly vocabulary for OPC-UA binding
13:37:28 [McCool]
kaz: wondering if expected relationship would be included in current liaison
13:37:56 [McCool]
... may have to talk to W3C management again to see if we need a stronger liaison
13:38:09 [McCool]
... especially if a spec is being created
13:38:40 [McCool]
kaz: for example, SDW group worked with OGC on joint specs
13:39:01 [McCool]
sk: probably first need to sketch the charter, then can share with W3M to get feedback

13:39:47 [McCool]
mjk: does this *have* to be done under OPC-UA? Are IP policies consistent with W3C?
13:40:14 [McCool]
sk: if we do it as a joint charter, we can include W3C members that don't have to be OPC-UA members
13:40:52 [McCool]
mjk: we should also look at certification requirements
13:43:02 [McCool]
ml: what mjk said is important, so we need to fix policies around IP, goals, etc.
13:43:13 [mjk]
ack mjk
13:43:45 [McCool]
ml: some clear use cases and scenarios that bring value to industry; what is benefit of integration?
13:44:12 [McCool]
ml: need some draft terms of reference
13:45:08 [McCool]
ml: in general this also applies to integration with other standards, e.g. MQTT

13:45:27 [McCool]
q?

ml: does it make sense to write a use case?
13:45:50 [McCool]
q+
13:46:19 [kaz]
ack k
13:46:22 [McCool]
kaz: before create a draft charter, perhaps we should have expected deliverables
13:46:47 [mjk]
I would like to understand if a WoT TD binding for OPC UA will create an open user community, like the web
13:47:06 [McCool]
sk: we would benefit if other standards can use WoT
13:47:35 [mjk]
So a zigbee binding, if only useful to zigbee members?
13:49:14 [McCool]
mm: we could add OPC-UA to existing use cases (eg factory, smart city, building, etc) but perhaps another "horizontal" use case for "cross-standard mashups" would be useful to document this application of WoT (which includes OPC-UA but also other standards)
13:49:48 [McCool]
kaz: suggest we should see how to use our existing W3C liaison
13:50:12 [McCool]
mm: and we should clarify if OPC-UA joint group is needed
13:50:58 [McCool]
sk: next steps, we should look at alternatives

13:51:29 [McCool]
mm: don't think anyone is against it, we just need to go through the process
13:51:51 [McCool]
sk: perhaps should start with sketching a charter, then we can discuss
13:51:58 [McCool]
ml: makes sense; is there a template?

13:53:48 [McCool]
mm: there are a few other topics of future interest from ISO and IEC (Common Data Directory)
13:54:33 [McCool]
kaz: had discussion with Mitsubishi Heavy Industries; maybe invite to use case call
13:54:49 [McCool]
... and also it might be interesting to refer to their ontologies
13:55:03 [McCool]
sk: kaz, will you invite to use case call then?
13:55:07 [McCool]
kaz: yes

s/Mitsubishi Heavy Industries/a guy working on the IEC CDD standard/
13:56:13 [McCool]
dape: how to identify version
13:57:54 [McCool]
mm: security worked on PRs for apikey and psk, and uri templates
13:58:20 [McCool]
mm: for discovery, talked about vocabulary and alternativeResponses
13:58:36 [McCool]
mm: all of the above will be discussed in TD call today
13:58:48 [McCool]
sk: for marketing, looked at videos and web pages
13:59:23 [McCool]
... for web page content, looked at tutorials
13:59:43 [McCool]
mm: plugfest, worked on logistics and got started in organizing repo, scenarios, etc.
14:00:19 [McCool]
sk: several prs that need input from ml
14:00:32 [McCool]
ml: unfortunately hard for me to attend td call
14:01:09 [McCool]
kaz: had a report last week on this
14:01:30 [McCool]
ml: consolidated repos, walked some new members through process
14:02:29 [McCool]
ml: architecture, terminology definitions for partial TDs, TD fragments, etc. to get consistent use of these terms
14:02:48 [McCool]
