Wiki clean-up

Architecture wiki

Lagally: (goes through the Architecture wiki)
… archival of last year's content

McCool: like the main wiki, we can archive old contents
… would suggest we use the same name convention as the main wiki
… just added a leading slash before the year like "/2021"

main wiki

Lagally: let's go for it
… let's create a GitHub issue for that

Issue 889 - Cleanup Wiki pages

McCool: can handle it since I need to do it for the main call too

Publication schedule

wg-2021-extension-plan.md

McCool: when to publish the CR drafts?

Kaz: planning to publish TD and Architecture tomorrow
… regarding Discovery, need to talk with PLH, but if he's OK, we can publish it as well tomorrow

McCool: what about the Profile WD?

Kaz: also tomorrow

Lagally: (updates the schedule based on the feedback)

(discussion on PR and REC transitions)

Lagally: (add some more updates to the schedule based on the feedback)

wot PR 1048 - Update wg-2021-extension-plan.md

Kaz: that implies the REC publication will be the end of June
… in that case, we should rather ask W3M for 5-mo extension instead 4
… I'll talk with PLH about Charter extension today anyway
… so will ask him about his opinion about this point

McCool: yeah
… let's check with PLH

Testing

WoT Architecture Implementation Report

McCool: there are some problems with test tooling
… but that should not impact the WoT Architecture spec

Dedicated call with implementers + developers

Lagally: should we have a dedicated call with implementers + developers?

McCool: would be a good idea
… maybe one in English and another in Japanese
… not 100% sure if the Ege's categorization of the assertions is good

Issue 888 - Evaluating At Risk Assertions

Kaz: agree
… we can use Ege's analysis as the basis but should validate it and finalize the evaluation

Kaz: let's have some discussion using a dedicated MD file based on Ege's analysis
… so that we can improve the analysis result using PRs later

McCool: good idea

Lagally: (creates an MD under wot-architecture/testing)

Issue 888 - Evaluating At Risk Assertions

(discussion on what we really meant for each assertion)

Kaz: as already mentioned previously, using TD to express the device capability itself is a kind of abstraction of device interface
… so any WoT implementations should pass 34 and 35

McCool: that's true but there is an additional requirement for a security later for WoT runtimes

Kaz: in that case, probably we should clarify our expectation includes two levels, 1. using TD to express device capability and 2. additional abstraction for security purposes

Kaz: to be strict, we should have clarified what part of each assertions to be implemented by whom (including external non-WoT systems)
… that could be explained by a guideline document as already proposed
… and potentially need to update the WoT Architecture spec itself in the future
… but we need clarification on what/how to test each feature from the current WoT Architecture 1.1 spec now

Lagally: yeah
… let's continue the analysis

PR 890 - Update At-Risk-Requirements.md
