Meeting minutes

minutes

<McCool> Feb-16

McCool: small typo s/late/wait

no objections

McCool: minutes can be published

quick updates

Lagally: architecture meeting canceled this week

McCool: no editors' call this week

McCool: consistency check between the documents still ongoing

Lagally: indeed, no recent discussions about this

Lagally: terminology has been discussed

Lagally: editors of Scripting and Discovery should take a look

McCool: we will discuss in the editors' meeting with the task forces

Daniel: from Scripting parts, small changes needed, already agreed

Lagally: PRs would be preferable, otherwise issues

<McCool> MM: also probably a PR from discovery

WoT Japanese CG

Mizushima: planning to hold an open event about ECHONET liaison. the agenda is being finalized and should include the relationship between WoT and ECHONET Lite Web API based on concrete use cases.

conformance statements

McCool: we have a resolution to proceed with this

McCool: KA, MM and SK discussed the process
… we can have normative statements in Notes, but it's the WG terms not the W3C terms, therefore compliance will be handled by the WG

McCool: today we can have a resolution and notify the AC reps from the WG

Kaz: this is not required by the W3C process, but the Notes are not covered by the IPR policy, so indeed the AC reps should be consulted

<McCool> proposal: proceed with adopting conformance statements in the Scripting API Notes, after notifying the AC reps of the WG and asking if there are any objects

<McCool> proposal: proceed with adopting conformance statements in the Scripting API Notes, after notifying the AC reps of the WG and asking if there are any objects; see https://lists.w3.org/Archives/Member/member-wot-wg/2022Jan/0022.html

Lagally: not clear what is going on and why are we doing something like a REC spec but which is not a REC spec

Kaz: the spec could say it is not covered by the W3C patent policy

McCool: OK, we should quote the exact text and let people have feedback on it

Kaz: the text is the same as for WoT Use Cases, but the content of Scripting is different

McCool: if any AC rep objects, we need to re-discuss it

<kaz> This document was published by the Web of Things Interest Group as a Group Note using the Note track.

<kaz> Group Notes are not endorsed by W3C nor its Members.

<kaz> The W3C Patent Policy does not carry any licensing requirements or commitments on this document.

<kaz> This document is governed by the 2 November 2021 W3C Process Document.

McCool: or make it on the REC track

Lagally: I would support the REC track, since it's more clear

McCool: there are also problems with that - we need a non-normative draft that may use normative languages

Lagally: what is the publication schedule, is it aligned with the other specs?

Daniel: usually a bit lagging behind the other specs (TD, Discovery etc)

Daniel: the Note track also exists for CGs, so it is not new
… the Note track doesn't mean we cannot switch back to the REC track
… we should allow clear statements in the spec

Daniel: what does it mean to ask the AC reps, what scenarios might happen?

McCool: we are asking the members if they accept liabilities, since it is outside the W3C patent policy

Lagally: liabilities mean violations of the W3C patent policy?

McCool: technically yes, Notes are more complicated

<McCool> proposal: proceed with adopting conformance statements in the Scripting API Notes, after notifying the AC reps of the WG and asking if there are any objections; see https://lists.w3.org/Archives/Member/member-wot-wg/2022Jan/0022.html

McCool: if we go through the IPR exclusion process, it would add a lot of overhead
… but if the spec says it is using normative language, but it is not normative, that should be fine

Zoltan: Scripting uses conformance classes that are needed, so being able to use normative language should be possible, with the big switch making sure they are not actually normative

Kaz: there can also be a normative Note, but in that case the WoT WG is responsible (not W3C as a whole) about the potential patent issues, so McCool and Sebastian wanted to talk with the group participants during this call.

McCool: will draft an email with KA and SK
… make it clear that this is only a language construct

Lagally: I support clarity, email, review by AC reps

Lagally: otherwise multiple companies might question this practice, and might become complicated

<McCool> proposal: strike committee to develop an email with precise details on implications of proceeding with adopting conformance statements in the Scripting API Notes, and define a process including notifying the AC reps of the WG and asking if there are any objections; see https://lists.w3.org/Archives/Member/member-wot-wg/2022Jan/0022.html

McCool: if any AC rep objects, we need to discuss what to do

McCool: I suggest we discuss this in the next editors' call

<McCool> proposal: strike committee consisting of editors to develop an email with precise details on implications of proceeding with adopting conformance statements in the Scripting API Notes, and define a process including notifying the AC reps of the WG and asking if there are any objections; see https://lists.w3.org/Archives/Member/member-wot-wg/2022Jan/0022.html

McCool: any objections?

Lagally: to discuss the email?

McCool: yes, and md file with content of email and process

<McCool> suggest we strike committee consisting of editors to develop an email with precise details on implications of proceeding with adopting conformance statements in the Scripting API Notes, and define a process including notifying the AC reps of the WG and asking if there are any objections; see https://lists.w3.org/Archives/Member/member-wot-wg/2022Jan/0022.html

Publication

McCool: kaz is working on the pubrules checker
… have some issues to be resolved

Lagally: think we should use the latest template

Kaz: ReSpec automatically generates the template, so we could simply specify "NOTE" as the type instead of "ED"
… but we still need to modify the document in addition to the issues caused by the type mismatch

McCool: ok
… what about TD?
… would clarify some issues during the TD call today
… Discovery to be finalized next week

Lagally: discussion about event handling
… would ask keep the door open for that

McCool: depends on what "keep the door open" means here
… we still have one more round before CR transition
… spec freeze this time is mainly for the Plugrest/Testfest

Lagally: ok

Wide review

McCool: some progress
… security tf finished first request
… one questionnaire should work for all the specs
… one answer for everything

McCool: this is a branch in the wot-thing-description repo

McCool: please look at the PR 1382 above
… still have to write up tests
… to be discussed during the test call today
… could apply one explainer for everything

Sebastian: had look at the explainer
… probably need more practical explainer
… with practical examples
… should improve it

McCool: would assign that to Sebastian :)

Sebastian: need explainers for the other specs too

McCool: let's finish the text first for TD, then think about others after that

Kaz: so we'll this (Explainer and Review Request) for TD as a template for the other specs?

McCool: rather one explainer document with multiple sections for the other specs

Kaz: ok
… that's also fine
… in that case, we should talk about this as well during the next Editors call

McCool: think so
