Meeting minutes

Profile discussion - continued from the Profile call

Lagally's slides

Lagally: (explains the slides on the high-level structure of the WoT Profile spec)
… [HTTP Baseline + Common Constraints]
… [Webhook +SSE Events]
… [Alternatives]
… possible options for the net steps

A. Dont' publish Profile REC within this Charter, defer to nxt Charter
B. Publish the Profifil as a WG Note in this Charter period
C. Publish the Profile 1.0 as a REC ,make event mechanisms non-norative
D. Publish Profile 1.0 as a REC with "HTTP Baseline" only

Lagally: event handling is still tbd
… Option C suggests publishing event mechanism non-normative in Profile 1.0 normative in Profile 1.1 after sufficient plugfests
… Option D suggests publishing Profile 1.0 only with "HTTP Baseline"
… Option A suggests not publishing Profile as a REC within this Charter period

McCool: Ben was in favor of option A here
… a compromise is take option C or D
… publish it in early stage in the next Charter
… we simply carry it forward
… 2 deliverables here, 1.0 and 1.1
… 1.0 just with HTTP Baseline
… can't wait until everything is done

Lagally: tx for your proposal
… however, would like to go for option C or D
… we now have good momentum
… and would like to continue to use it

Daniel: no strong opinion
… but going forward to REC requires two implementations
… possible Oracle and WebThing
… but not really sure at the moment
… Scripting API doesn't have enough support for WoT Profile yet

McCool: Actions is on the border line now

Lagally: not Actions in general but just sync/async Actions

Daniel: Events to be postponed, and even Actions still in flight from my viewpoint

Lagally: why don't you join the Profile call and join the discussion on the remaining difficulties?
… would try to meet all the requirements of the whole WG
… would go for option D when we're confident

Ege: would agree with Ben for option A here
… don't like 1.1 specs due to potential backward compatibility issues

Kaz: we should clarify all the remaining issues, e.g., those mentioned during this call, and register them to the wot-profile repository
… and discuss the details during the Profile call rather than this call today

Lagally: ok
… on the other hand, kind of concerned about the procedure
… wondering about when/how to close the discussion

McCool: would like to check if we have the Profile call next week

Lagally: no Profile call next Wednesday, August 17

(so the next Profile call will be on August 24)

WoT F2F meeting around TPAC 2022

McCool: how to organize the Pre-Meeting?
… do we want to have 2h meetings over five days as usual?

(no objections)

McCool: think we need enough time for discussion

Kaz: +1

McCool: Kaz and I will work on the logistics then
… we need to cancel all the other (ordinary) meetings
… during the pre-meeting on Sep 5-9

TPAC f2f

McCool: TPAC agenda next
… given the pre-meeting, would be good to have just summary during TPAC on Monday

McCool: TD was published on August 3
… Discovery was also published today
… CR transition expected around August 31

McCool: we'll discuss the CR publication during the Pre-TPAC meeting
… can think about the latest WD as the CR candidates

Kaz: maybe there are some recent updates after the published WD

McCool: would expect the recent updates are minor
… but the latest ED might be better
… (generates proposal for resolution)

Testing

McCool: approved the minutes from the Testfest
… am working hard to keep the latest implementations on the specs' repositories (on the main branch)
… TD has 37 unimplemented features
… 15 features with only one implementation
… will grab these numbers
… and put them on the agenda
… related issue on i18n
… features around Discovery are still at-risk
… still in-flight is Architecture
… some of the assertions are not testable as pointed out by TAG
… the rest are straightforward
