approving previous minutes

no objections

<dape> https://www.w3.org/2021/10/25-wot-script-minutes.html

Daniel: note that we discussed what to do in the next charter, to be tracked in an issue

ACTION: DP creates issue for tracking charter changes

no objections

Daniel: last week we had joint call with Security TF

<kaz> Nov-8 Security call minutes


Zoltan: we discussed onboarding, provisioning, discovery, management APIs, etc. See issues in the minutes.

Daniel: will list these for the new charter

node-wot release

Daniel: we are publishing a Note and then update node-wot
… but at the moment no need for an updated Note

PR 350

<dape> https://github.com/w3c/wot-scripting-api/pull/350

Daniel: related to the link checker

Daniel: the PR fixes the broken links and typos

<dape> Broken fragments: https://w3c.github.io/wot-thing-description/#securityscheme (line 3948) https://w3c.github.io/wot-thing-description/#nosecurityscheme (line 3948)

Daniel: some of the errors were false

Kaz: we should generate a static html first, only then apply the validator
… There might be some option for that purpose, but, need to consult the validator checker doc

Daniel: suggest merging this PR and then do the rest separately

Zoltan: fine with that

Daniel: merged


Clarify multiple requests for subscription/observation

<dape> https://github.com/w3c/wot-scripting-api/issues/346

Cristiano: when we subscribe, should also record how to unsubscribe

Daniel: this as also discussed in the TD TF,

Cristiano: but it's not yet in the spec, may come only in the next charter

Cristiano: it's about choosing a Form for unsubscribe

Cristiano: implemented a scorer algorithm for determining how to unsubscribe
… but we should change the TD spec to link the unsubscribe Form

Daniel: can we subscribe via HTTP and unsubscribe via CoAP?
… how should it work?

Cristiano: we don't have practical use cases for that, but I think we should have the same binding

Zoltan: I agree, also for security reasons

Daniel: there is no statement to prohibit this use case

Cristiano: it's a validation problem

Cristiano: the TD should be invalid if it didn't have unsubscribe Form

Daniel: right now the matching algorithm could possibly use the Form from any binding

Zoltan: IMHO we should create an issue to track this, and update the algorithms in Scripting, to be precise

<dape> https://github.com/w3c/wot-thing-description/issues/968

Daniel: this depends on the TD TF to solve.


subscribeEvent and observerProperty misaligned signature

<dape> https://github.com/w3c/wot-scripting-api/issues/343

Cristiano: we can track this problem in a dedicated issue

<dape> https://github.com/w3c/wot-scripting-api/issues/351

Daniel: then we also have an issue about the multiple subscriptions

<dape> https://github.com/w3c/wot-scripting-api/issues/346

Cristiano: currently if subscribed, the next call will fail

Zoltan: that is good enough for now

Daniel: time is up, continue next time

<kaz> [adjourned]
