WoT Japanese CG

Kaz talks about the new Japanese WoT Japanese CG. they're planning to hold an online event later February. Mizushima-san could give some more details.

Mizushima-san gives more details

McCool asks if we can update our new Web pages to link to the new CG

<dape> CG area within the new WoT Welcom page

Daniel provides some details

McCool: we should link to the WoT JP CG from our marketing pages

<Mizushima> wot-jp cg homepage

Renaming the "master" branches to "main"

McCool: we were asked to rename our Master path on GitHub to Main. I've tested this in my own fork.

People need to update their local copies on their own computers.

McCool: I have a few more things to do and will then draft some detailed instructions. Any PR's against the Master path need to be applied before we do the updates

Michael shows us some of the details

Lagally: what's the purpose, what will happen to the original?

McCool: I think but haven't tested that pending PR's will be automatically rolled over

Github has been a little unstable recently ...

So taking things cautiously

Goals and Objectives

Our CEO, Jeff Jaffe is asking for the objectives we are setting ourselves for this year. This can include our publication roadmap, any workshops we plan to do, measurable progress with our liaisons, and best of all metrics for adoption by industry and targets for member recruitment.

Any idea of how we can answer Jeff?

Some of this is around marketing, and industry outreach

We want to set some achievable objectives according to what we want

McCool: what do we do in respect to contacting industry prospects

Sebastian: we're starting a joint activity with OPC and this should be one of the objectives as an important step for a WoT binding to OPC

McCool: how should we organise this? I could create a markdown file in GitHub?

kaz: please note that the W3C Objective is related to the Industry Team, and the Industry Champions including Dave for WoT and myself for Smart Cities are in charge of generating the Objectives documents.

what I as the WoT Team Contact would like to ask the group to think about is rather clarifying the existing targets and expectations. for example, what I suggested during the marketing call and the use cases call yesterday. extending the timetable for spec generation might be a good starting point.

McCool: we need a clear place for where we keep those objectives

He creates an issue to kick this off
… along with a markdown file "goals.md"

The issue is #956 "Capture objectives and goals"

<McCool> https://github.com/w3c/wot/issues/956

Lagally: what is the lowest entry level for compliance with WoT

I believe that we need to have the entry barrier very low

We also need to encourage convergence by the Mozilla web things

McCool: a tutorial would list what components you need to build a WoT compliant solution

McCool: we need to raise our visibility and encourage adoption

We're working on our marketing plan with a March 1st milestone

Ege talks about microcontrollers

McCool: for a product the cheapest device, along with a hub device ...

Lagally: we should talk about this in the architecture call

Sebastian: the Mozilla web thing community meet regularly, and have plans for W3C WoT compliance for 2.0 version

kaz: is Ben Francis still leading the Web Things community?

McCool: I think so

<kaz> kaz: in that case, we can chat with Ben directly too :)

Plans for joint calls

Michael reviews the pending plans for joint calls with external groups, WebThings (Mozilla), Microsoft DTDL, IEC CDD, ...

plugfest and Virtual F2F planning

David: I wanted to ask about thingweb.io, which talks about Raspberry Pi a lot

McCool: we want to provide instructions for running node-wot
… it would be my preference for a reference platform

<Zakim> dezell, you wanted to ask about thingweb.io

<Ege> https://github.com/tum-esi/wot-sys/tree/master/Devices/ESP-lightsensor esp based lightsensor here

Michael Koster talks about some development hardware options

NodeMCU is based on ESP8266 chip plus WiFi

We should talk about a tutorial for a minimally conformant systems

<Ege> https://github.com/tum-esi/wot-sys/tree/master/Devices/ESP32-ledSwitch

Further discussion in the plugfest call ...

Sebastian has implemented support in the Lua stack

Michael wonders if node-wot can be made to run on small devices

Sebastian: TUM have some baseline implementations

<Zakim> kaz, you wanted to suggest we talk about the detail on implementations during the plugfest call again :)

<Ege> https://jerryscript.net/ this would also run an esp32

F2F planning

McCool: We've arranged webex for the face to face, but need to prepare the agenda

<mjk> We should eventually have a common reference stack for embedded platforms (C/C++)

Kaz: one hour for a joint discussion with IEC

McCool: let's try to arrange the calls with other external groups on the same day

Each task force needs to add their own agenda topics

McCool asks Michael Koster about joint call on oneDM and ASDF, should this be done in the IETF?

Koster: I don't think there will be time during the IETF meeting

<McCool> https://github.com/w3c/wot/blob/master/charters/wot-ocpua-2021-charter-draft.md

Sebastian is proposing a cooperation document and sub group for WoT/OPC

McCool: I think this is essentially about protocol binding, but these are not part of our charter in respect to normative specs

Kaz: informative would be fine for now given the Charter says Protocol Binding is informative. also we can have further discussion during the TD call later today.

<kaz> Charter

McCool: I have a draft proposal for gelocation and am working with Christne Perey on this

TF reports

Sebastian provides a quick status report from Marketing TF, good progress on web pages

<dape> see https://w3c.github.io/wot-marketing/ and https://github.com/w3c/wot-marketing/issues

Launch date for new pages is March 1st

<dape> wot-marketing issue 118

Please review by end of Feb

McCool: we should think about a clean experience for developers new to WoT

<Zakim> aks, you wanted to discuss general marketing feedback w.r.t. "is everyone" ok with the current approach

Lagally: when will we do a resolution on the new pages?

McCool: not today, but definitely to mark that we're comfortable with the launch

Feel free to propose PR's if you have some ideas for improvements
