Quick updates

   McCool: currently in the IIC meeting
   ... a couple of discussions including digital twins
   ... looks like TD
   ... 2nd thing is Intel IoT DevFest
   ... submitted an abstract and it's accepted
   ... updated the abstract and sent it to the mailinglist

   [14]McCool's proposal

     [14] https://devfest.intel.com/intel/live/28/page/288

   Matthias: tx

   Lagally: first of all, interested in the IIC digital twin
   presentation
   ... any public information about that?

   McCool: IIC stuff is Member-only...

   Lagally: there will be ISO/IEC JTC1 meeting in China
   ... our AC rep is participating in it
   ... and will make presentation about W3C WoT
   ... hope that's fine by everybody

   Matthias: good
   ... also attended one of the JTC sub committee meetings

   Lagally: high-level overview of architecture, etc.
   ... material is focused

   Matthias: is that fine by all?

   McCool: yeah

Charters

   Matthias: we have a draft Charter for IG

   <mkovatsc> [15]Draft IG Charter

     [15] https://github.com/w3c/wot/blob/master/charters/wot-ig-2019.html

   McCool: (btw, AC meeting presentation might be a good starting
   point for the high-level overview)

   Matthias: the above
   ... need resolution for it
   ... is there still any outstanding issue?

   Kaz: I'm OK with the proposed Charter myself
   ... but some discussion on GitHub
   ... issue 599

   [16]Issue 599

     [16] https://github.com/w3c/wot/issues/599

   Kaz: would suggest we simply say "we'll work on use cases and
   requirements..." like the MEIG Charter
   ... don't have to define concrete documents for IGs

   [17]MEIG Charter draft

     [17] https://www.w3.org/2019/04/me-ig-charter-draft.html

   Lagally: need another iteration?
   ... some consideration for the workshop as well?

   Matthias: the idea to keep the IG Charter flexible
   ... workshop discussions for the WG Charter mainly

   McCool: that's my point as well
   ... IG works on general/high-level ideas
   ... WG Charter needs more detailed discussion, though

   Kaz: right
   ... we should bring our fixed version draft to W3M quickly so
   that we can get their review soon

   McCool: how about making resolution by email by Monday, May 27?

   Matthias: can work on the draft Charter
   ... make the deliverable open
   ... just list some possible topics

   Kaz: yes, possible topics

   McCool: what about IG Chairs?

   Matthias: can have detailed discussion during the f2f?

   McCool: right

   Matthias: next WG Charter
   ... will pick up topics during the workshop
   ... and have discussion during the f2f

PR publication tasks

   Kaz: we published CRs for TD and Architecture on May 16
   ... thanks a lot for your contribution, Editors and all!

   Matthias: thank you very much!
   ... we could publish them officially

   [18]PR 709

     [18] https://github.com/w3c/wot-thing-description/pull/709

   McCool: updated test results to be confirmed
   ... there are still some errors
   ... please update your TDs

   Kaz: where is the latest working area?

   <McCool>
   [19]https://github.com/w3c/wot/tree/master/testing/tests/2019-0
   5

     [19] https://github.com/w3c/wot/tree/master/testing/tests/2019-05

   McCool: updates from Fujitsu and Oracle there
   ... please make your updates as well
   ... really need updates

   Lagally: tx for looking into the TDs
   ... will review it

   McCool: still some errors and need updates
   ... need SmartThings, etc.

   <McCool>
   [20]https://cdn.statically.io/gh/mmccool/wot-thing-description/
   updated-test-results/testing/report.html#test_class

     [20] https://cdn.statically.io/gh/mmccool/wot-thing-description/updated-test-results/testing/report.html#test_class

   McCool: would emphasize that at-risk features are low priority
   ... non-at-risk items are the priority
   ... we need to update all of them
   ... looking through here...
   ... we need both clients and servers
   ... there is missing parts due to people have not done both
   ... here updated template for CSV

   [21]Template for CSV

     [21] https://github.com/w3c/wot-thing-description/blob/master/testing/inputs/results/template.csv

   McCool: strongly would suggest people update the info using
   this

   Ege: question
   ... some assertions named "td-*-type"
   ... these are not really clear

   McCool: should be validated based on JSON Schema
   ... if you don't have array at all, not to implement

   Matthias: in section 6, there is a mapping rule
   ... and listed under 6.3

   [22]Section 6

     [22] https://www.w3.org/TR/2019/CR-wot-thing-description-20190516/#sec-td-serialization

   [23]Section 6.3

     [23] https://www.w3.org/TR/2019/CR-wot-thing-description-20190516/#td-class-serialization

   Matthias: you can check the definition

   McCool: automatically testable?

   Ege: yes
   ... also there is a new word, "signature of class"

   Matthias: two terms input/output for example
   ... don't fully understand these type things here

   (e.g., "td-map-type")

   Ege: if we have any class for security, etc., that class is
   pass

   (e.g., for "td-class-type")

   McCool: also mention an error on "td-map-type"
   ... already fixed within my PR
   ... go back to the report.html
   ... most of them pretty easy
   ... multi languages, etc., here
   ... there are some additional "0 implementations" features

   Ege: general consideration whether pass or not
   ... think there is some error

   (e.g., "td-arrays-forms")

   McCool: some errors around here
   ... caused by duplicated ID
   ... goes through the other assertions
   ... fancier options on data schema here
   ... these are not marked as at-risk but may be at-risk (not
   high priority, though)
   ... td-vocab-href--Form
   ... we have many red assertions for security here
   ... content negotiation and language things are priority

   Kaz: tx
   ... we should update the timeline and clarify the schedule so
   that we can finalize this report by June 13
   ... maybe we need to assign people to remaining features like
   we did during the Princeton meeting

   McCool: would get volunteers

   Kaz: some more discussion during the testing call today?

   McCool: can't make the testing call today...

   Matthias: question to Daniel
   ... quickly cover some of the assertions?

   <dape> [24]thingweb.node-wot Issue 88

     [24] https://github.com/eclipse/thingweb.node-wot/issues/88

   Daniel: e.g., the language part
   ... language thing, HTTP namespace, etc.

   Matthias: @language could include Web UI?

   Daniel: need to check

   Matthias: good to have discussion during the testing call
   ... node-red implementation by Hitachi could be also a
   possibility
   ... we should have brainstorming about the plan

   Lagally: we should have the call the call today for demo prep?

   McCool: let's talk about testing offline

   Matthias: please create an issue about the testing plan if
   there is any problem
   ... any update on TAG review?
   ... seems not

   Kaz: postponed till May 21
   ... we should check with Daniel as the TAG Chair
   ... there are 2 approaches for security review, TAG and
   IIC/Intel internal

   Matthias: can also send a message to IRTF T2T guys

   McCool: would be helpful

   Kaz: shall I send a reminder to Daniel Appelquist?

   Matthias: yes, please

   Kaz: will do

Test Cases and Report

   [25]proposed schedule

     [25] https://www.w3.org/WoT/IG/wiki/PlugFest_WebConf#Schedule

   Matthias: how to deal with that?

   Kaz: we can simply say "we're generating the implementation
   report"

   McCool: right

   Kaz: think we can explain where to put the TD data (on GitHub)
   and how to use the tools (manually or automatically) within the
   implementation report itself

Workshop and Demos

   <mlagally> [26]Workshop agenda page

     [26] https://www.w3.org/WoT/ws-2019/schedule.html

   Lagally: the draft agenda has been settled as above
   ... will have discussion with W3M tomorrow
   ... keynote speech on Wednesday also settled
   ... if you submitted a position paper, please see where your
   talk is assigned
   ... the whole things should be done smoothly, so please check
   pc connectivity, etc., beforehand

   Ege: question about OpenDay

   Kaz: we need some more discussion with Sebastian about that
   part

F2F

   Matthias: if you've not registered, please get registered asap
   ... there is a registration site and a f2f wiki

   Ege: any possible sponsor for catering?
   ... for coffee break; not lunch

   Kaz: let's try some coffee ourselves like we did in Korea :)

   Ege: ok

   Kaz: tx a lot for your help, Ege!
