any objections?

no

IANA TM content type registration

https://github.com/w3c/wot-thing-description/issues/931

references to the security sections are now fixed by WD4

<kaz> RFC 6901

IANA suggest also to add section 6 of the RFC6901

any objections?

Daniel: maybe its not good to link to specific setions which may changed in the future

I think the document is stable and will be not changed anymore

otherwise a new RFC will be published

I accendenty commited this new text to the main

https://github.com/w3c/wot-thing-description/issues/931

the section 6 should have a seperate link othwerwise it goes to section 3 only

PRs

#1564

https://github.com/w3c/wot-thing-description/pull/1564

<kaz> preview - 5.3.4.2.2 Response-related Terms Usage

Ege: I draw another kind of representation. Kind of decission tree
… please comment on this or you have another ideas for a compact representation
… since this is just informative, can be also included at later point such as during CR review phase or transition

#1630

https://github.com/w3c/wot-thing-description/pull/1630/files

JSON Schema fix for instanceName

Kaz: back to PR 1564, it depends on whether we want to express the rule as (1) combination of possible options or (2) some kind of algorithm. We might want to ask Zoltan for opinions about a possible representation

decide to merge #1630

#1638

https://github.com/w3c/wot-thing-description/pull/1638

Ege: can it be that some assertion where removed for security, can it be?

McCool: yes this is ok

we discussed this last week already

decided to merge

#1649

https://github.com/w3c/wot-thing-description/pull/1649

<kaz> preview - 9.3.3 Composition

Daniel: a recommendation also allows to use a complete different strategy, right?

yes

Kaz: we're using JSON-LD as the basis for TD and TM, so we could define some additional namespace to distinguish instanceName. Maybe also ask JSON-LD for some advice

Cristiano: for consumer this flexiblity makes everything complicated since it is maybe not identifyable where which property definitions is comming from

decided not to merge yet, another iteration is needed

Kaz: btw, basically this issue (=Issue 1556 which is the basis of PR 1649) is related to the mechanism of objective programming language's inheritance between a Class and an Instance. So we should have that viewpoint as well.

#1652

https://github.com/w3c/wot-thing-description/pull/1652

Ege: I think there is no need to define an assertion for this. An explaintion would be enough

McCool: I agree with Ege

ok, will ne not be merged. I will provide an update

#1653

https://github.com/w3c/wot-thing-description/pull/1653

Ege: just a JSON Schema extension for security definitions

Cristiano: there is a script that takes over from TD Schema to the TM Schema. We should check if this is not result a manditory definition in TMs, which shouldn't

Ege: I will check later and will merge this PR then

group is ok with it

#1654

https://github.com/w3c/wot-thing-description/pull/1654

Ege: there is a popular python validation that is not working with the current 'items' definition

Cristiano: is it a bug by our schema or by the implementation?

Ege: its a bug in our schema
… prefixItems means everything is in order. Its still an array.
… however, I'm waiting for some feedback form the JSON Schema authors. Maybe they have some additional comments.

ok, then lets wait until they response to Ege's mail

#1657

https://github.com/w3c/wot-thing-description/pull/1657/

we should rename "object properties" to "definitions"

#1658

https://github.com/w3c/wot-thing-description/pull/1658

decided to merge

<McCool_> https://www.w3.org/International/wiki/Html-bidi-isolation

#1660

decided to merge

decided to merge

#1558
