TPAC

Accessibility

McCool: which slot should we pick for the accesibility
… we can pick our slot on thursday afternoon

Ege: I would prefer using our slots for WoT specific discussions

Kaz: Our charter says that accesibility is very important, and they're getting interested in accessibility for WoT services as well as ordinary Web contents. So it's good timing to have a joint meeting with them in person during TPAC 2023.

Thursday 14.09 at 11:30 – 13:00 Friday 15.09 at 11:30 – 13:00 and at 17:00 – 18:00

Ege: I think we can pick their slots still

WoT CG

Ege: there are slots available from CG as well

McCool: let's put this into the agenda

Ege: I can organize

Ege: should we remove the categories above?

McCool: yes, you can fill the details later on

Kaz: I cannot join due to conflicts with the MEIG but a chair should join

Press Release

w3c/wot-marketing#425

McCool: we can meet as chairs and discuss or we can do it in the marketing call

Ege: we should agree on who writes the introduction

McCool: we need to set the narrative for the Press Release

Meetups

McCool: (writes to the wiki on the WoT-CG and the WoT-JP CG)

Social Media

Ege: there are issues with Twitter lately

https://twitter.com/W3C_WoT/status/1678761340423507975

Kaz: wondering if we need to work on the other messenger app like LinkedIn, because the more apps we work on, the more effort would be required

Sebastian: also a bit concerned about working on multiple apps

Ege: we can manage multiple platforms from a single app, which reduces the efforts

McCool: we should consider all our options. let's discuss this in the marketing call

Planning

Overall structure

<kaz> Sebastian's slides

Sebastian: I prepared slides (will be uploaded later)

Sebastian: <presents the wot 1.1 structure>

McCool: it is also missing a scripting API (that's a NOTE)

McCool: Architecture contains security assertions

Luca: API does not implement TD, but consumes

Kaz: My suggetion is not to add rdf-like relation to the components within this basic diagram, but simply list all the documents mentioning which is REC-Track, which is Note, which is Use Cases doc as the starting point, which is building blocks, etc., first.

Kaz: After that, for the next phase, we can see what is described within which document based on the ToC of each document

McCool: There two large clusters we have to organize: system and metadata

Sebastian: my plan is to pick each component and see what we agree about it for the next version

McCool: My proposal is to first reorganize the components in the two clusters

McCool: - System : Architecture, Discovery, Security, Use-Cases

McCool: - Metadata : TD, Bindings, Profiles (maybe)

McCool: profile may apply to both groups

McCool: it is ok to focus on a cluster at time

Kaz: I think this categorization is a good approach to start

Kaz: we should think which are building blocks and which are starting points (e.g. Security is a starting point, TD is a building block)

Kaz: a third category, Guideline could be also good to add

<Mizushima> +1 Kaz

McCool: we have to discuss in the context of the metadata cluster what profile involves

Kaz: UseCase is a starting point of the spec work

Kaz: profiles, that help interoperability come the last

McCool: Security comes across the different clusters

Luca: We should agree of what profiles fit

McCool: We discuss before a long time, we focus first on interoperability

Luca: hopefully we won't need specific profiles for Discovery

Kaz: I suggest not putting profiles in this diagram today

McCool: we have to keep in mind that we want to support bindings from other organization

Ege: we agreed to not have a separate binding template document

Ege: the binding template will be part of TD

McCool: We should call it Binding Registry instead of Binding Templates Registry

<McCool> (time check - 15m left)

Mizushima: we should first thing of the purpose of WoT 2.0 and then think on what to map to the document

Kaz: the WoT 2.0 had been discussed in the charter, we didn't state explicitly about the Binding Registry, so we can start today to keep it a Binding Templates document until we have full consensu on the Registry

Koster: That makes sense to me too. In addition, I wonder what about TM, are we going to have a separate document for it?

McCool: Back to Mizushima's point, we have to decide how much our focus on greenfield devices, and we need to figure out if we have gaps (e.g. Onboarding)

Ege: I think we should not restrict us to brownfield devices
… but not overfocus on greenfield

Ege: Everything that target Consumer is greenfield

Ege: Onboarding may be too big to tackle

McCool: We should experiment more on onbording to have an idea

Kaz: Agree that we need to clarify our scope and target areas, but we should start with the expectations from the industry

Kaz: and rely on the use-cases to extract requirements that lead to decisions

<McCool> (time check - we are now over)

Luca: We should make sure to make sure what we keep providing building blocks people can mix and match as needed (e.g. not using scripting API or TM)

<kaz> [adjourned]
