Agenda

   Lagally: we should talk about the liaison statement ...

Publication status

   Sebastian: where are we in respect to the publication of the
   updated Architecture WD?

   <kaz> [16]WoT Architecture is ready

     [16] https://w3c.github.io/wot-architecture/publication/ver11/1-fpwd/

   He shows the draft, Kaz is on the job for this and the other
   documents

   Kaz: I've checked the documents, but think we need a little
   more time and aim for publication next Tuesday

   <kaz> [17]WoT Thing Description has a remaining issue

     [17] https://lists.w3.org/Archives/Member/member-wot-wg/2020Nov/0008.html

Possible new slot for WoT Use Cases

   The WoT Use Cases call is rather too early for some people, and
   we are looking for another slot

   Sebastian: please respond to the doodle poll

   Lagally: we should consider alternating the slots to enable
   participation from people in widely spread time zones

   Sebastian: we tried that in the past but it was a bit confusing

   Daniel: I agree with that

   Sebastian: the use cases call is every 2 weeks, right?

   Lagally: yes. If we can't find a single slot that works for
   all, we should consider the alternating approach
   ... lets set the poll deadline to the end of this week

New patent policy

   The revised patent policy - we have a chance to decide whether
   to keep the old one or move to the new one?

   Sebastian: I will check with my company's lawyers to get their
   insights
   ... we need to hear from others ...

   McCool: we don't have to adopt the new policy, it involves work
   to do so, and perhaps the easiest option is to stick with the
   old policy unless we have a pressing need to change

   Sebastian: agreed

   Kaz: the chairs need to respond to the questionnaire for each
   WG, if we do decide to switch policies we will need to
   recharter

   Sebastian: that makes sticking with the old policy attractive

   If any company needs to change to the new policy, please let us
   know

   Lagally: is there a diff marked version for the two policies?

   Sebastian: yes

   Kaz: this should have been in the AC Members email from May
   2020

   <inserted> [18]diff between PP2017 and PP2020 (member-only)

     [18] https://www.w3.org/2020/04/PP-update-2020-March30-diff.pdf

input from non WG members

   Kaz: we're still waiting on Wendy Seltzer

ITU-T liaison statement

   Lagally: shows the draft statement

   We haven't yet looked at all the ITU-T SG20 documents as yet. I
   will upload the relevant documents to make them easier for us
   to review

   Lagally: do we make the liaison documents public?

   Sebastian: kaz can you clarify?

   Kaz: we usually forward the liaison document to the public
   list, but we can check with the ITU-T in this case

   Lagally: who will do the check? The chairs or me?

   Kaz: I will look after this

Minutes from last call

   <kaz> [19]Nov-11

     [19] https://www.w3.org/2020/11/11-wot-minutes.html

   Sebastian shows the minutes ...

   Any objections to making them public? [no]

   Sebastian: let's also check the minutes from our TPAC meetings.
   Please take a look.

   Kaz: the task forces should review the minutes from their
   perspective

   <kaz> [20]vTPAC

     [20] https://www.w3.org/2020/10/05-22-wot-minutes.html

   Sebastian: we can then approve them at next week's main call

upcoming events

   The IETF had a meeting on JSON Path and JSON Schema, anyone
   attend?

   Koster summarises the discussion and how it relates to our use
   cases. The take away is that we need to provide our use cases
   for their review.

   McCool: do we have a contact we can reach out to?

   Koster: Carsten is the best advocate I think

   McCool: Okay, we can discuss this and identify the important
   use cases for JSON Path

   JSON Path could be quite ubiquitous in our applications

   Koster: Two issues: 1) the syntax for paths, and 2) what's the
   expected result

   McCool: we need to look beyond discovery and also discuss this
   in a TD call

   Koster: Carsten wrote an initial draft for discussion in the
   IETF
   ... the other IETF meeting I attended was JSON Schema in
   relation to hackathons

   <McCool> [21]https://github.com/w3c/wot-discovery/issues/100 -
   issue to capture JSONPath requirements

     [21] https://github.com/w3c/wot-discovery/issues/100

   some discussion relating to enum and AnyOf

   Koster: I advocated for the IETF spec to cover events and
   actions as well as properties given that that is important to
   the W3C WoT useage

   some more people to support this would be helpful, the next
   ASDF meeting is Dec 14/15

   Koster: I will attend the CBOR meeting. There is some near
   final discussion on resource directories

Monday's joint call with IEC TC57 CIM

   McCool: we got some feedback from CIM group on use of SAREF and
   SOSA

   Two different binding conventions for properties, some
   challenges with subclassing

   we asked if there are any best practice guidelines

   we may want to produce a WG Note on that

   Some discussion about continuing involvement: as W3C Member, as
   invited experts or via liaison, kaz to look into that

   McCool: we need to figure out the purpose of the next call with
   them

   Kaz: as I mentioned during the joint call itself, I think it
   would be better to establish the liaison between IEC TC57 and
   WoT first

   They were certainly interested in using SSN/SOSA

   We could ask Victor

   Koster: who are the users for SAREF?

   McCool: distributed energy grids was the big use case

   I think the work is still at a proposed standard level

   David: listening to McCool, I strongly recommend keeping
   actions and events as they are really useful abstractions, e.g.
   for node-wot and node-red

   Koster: that's a super good point, so thanks

Upcoming joint calls

   Today we have folks from the Linked Building Data in the TD TF

   On Dec 9: meeting with the APA WG

   Still looking for a slot for meeting with the Spatial Data on
   the Web IG

   McCool: the OGC want to be part of the same meeting and suggest
   a 2 hour long call

   any objections? [no]

   Kaz: I am checking with who want to attend from their side

   McCool: let's try for December 10

   we can then work on the agenda

   Koster: one more report, we're working with folks on the SDF
   language and some other things

   <McCool> already an issue for SDWIG/OCG meeting, let's continue
   to use that: [22]https://github.com/w3c/wot/issues/939

     [22] https://github.com/w3c/wot/issues/939

   Koster: including SI units and inconjunction with the OCF

   Koster can't attend today's TD call, so we can discuss this
   next week

   Sebastian: anything important to share from the task forces?

   Please look at the proposed new web pages and provide your
   feedback

   <dape> [23]https://w3c.github.io/wot-marketing/

     [23] https://w3c.github.io/wot-marketing/

   we want to synchronise the release of the web pages and the WoT
   video

   Siemens and Bosch working on a new editing project - I will
   introduce that in the marketing call

   Kaz: we could talk about Ege's new testing code, WoTest, in the
   next hour (Plugfest slot)

   <kaz> [main call adjourned; Testing call will start 10mins past
   the hour]
