new WoT web page

   <inserted> scribenick: sebastian

   need some short abstract about the task forces

   including the task forces leaders

   <kaz> [14]Welcome page

     [14] https://w3c.github.io/wot-marketing/

   McCool: we should use a template for each section

   <kaz> [15]TD-TF

     [15] https://w3c.github.io/wot-marketing/activities/tf-td/

   <kaz> [16]Ege's issue 85

     [16] https://github.com/w3c/wot-marketing/issues/85

   McCool: there is an issue from Ege that gives an overview about
   the current content of all the task force wiki pages

   McCool: we should agree on a template
   ... who can help here to create a template?

   Ege can provide a template.

   Ege: Which points should be covered?

   McCool: Main page has the most contents and covers many points

   Ege: Discovery can be also used to create template

   Kaz: Daniel developed an CSS file for the webpage. Shall we use
   this for the template as well?

   McCool: Prefer the wiki style
   ... we should keep the wiki structure

   Kaz: we should have the detail structure of the MD files for
   task forces
   ... should discuss this in the marketing call

   Ege: [17]https://w3c.github.io/wot-marketing/activities/tf-td/
   is html file which will be not changed
   ... only the content of the wiki page will changed like the
   agenda

     [17] https://w3c.github.io/wot-marketing/activities/tf-td/

   Kaz: I'm OK with writing the details of each TF's activity
   using, but the discussion on the structure of the whole pages
   should be done during the marketing call

   Lagally: +1 that the structure should be agreed during
   marketing call

   Ege will prepare a proposal for the next marketing call

   next week marketing call is canceled

   so, will discuss this one week after

   Please other TF should also think about the content

   Lagally: Yes, should be not that complicated to provide some
   sentences about the scope of the TF

   <Ege> [18]https://github.com/w3c/wot-marketing/pull/99/files

     [18] https://github.com/w3c/wot-marketing/pull/99/files

Status TD 1.1

   Kaz: we should also provide the last minute changes in the
   index.html in github master

   <kaz> [19]Kaz's editorial updates for publication (Member-only)

     [19] https://lists.w3.org/Archives/Member/member-wot-wg/2020Nov/0015.html

TD 2.0 roadmap

   There were some discussion about TD 2.0 roadmap

   McCool: we should provide a CR 1.1 version in March to be on
   time

   <kaz> [20]Milestones calculator, fyi

     [20] https://w3c.github.io/spec-releases/milestones/?fpwd=2020-11-24

   McCool: it's quite tight in schedule
   ... different option such as work in parallel on TD 2.0 and TD
   1.1

   I think this is not a good idea

   Kaz: if we can not finish or start the work on TD 2.0 we need
   to get rechartered for ver 2.0 and some more possible
   additional deliverables

   <kaz> scribenick: kaz

   Kaz: wondering about the actual "roadmap" for 2.0 version

   McCool: let's get a poll about deferring the 2.0 version to the
   next Charter
   ... need to discuss during the main call as well, though

   <McCool> summary it seems we are leaning towards deferring 2.0
   to the next charter and focusing on 1.1 in this charter

Issue 999

   [21]Issue 999

     [21] https://github.com/w3c/wot-thing-description/issues/999

   Sebastian: provided an example
   ... (put the example TD to edi{TD}or)

   [22]Sebastian's comment including the example

     [22] https://github.com/w3c/wot-thing-description/issues/999#issuecomment-730421965

   McCool: need a list of placeholders?

   (like "URL_PLACEHOLDER, ID_PLACEHOLDER", ...)

   [23]Lagally's comment

     [23] https://github.com/w3c/wot-thing-description/issues/999#issuecomment-733655164

   Lagally: also versioning should be mandatory

   McCool: yes, it should be mandatory
   ... we should put version identifier in the id and "version"
   metadata

   Ege: how to handle major/minor/patch versions?

   McCool: several different views possibly
   ... TD is instance of model
   ... if we have a new version of TD, what would happen?

   Ege: depending on the use cases
   ... some people might think semantic versioning wouldn't work
   for API versioning

   <Ege>
   [24]https://w3c.github.io/wot-thing-description/#example-31

     [24] https://w3c.github.io/wot-thing-description/#example-31

   Ege: version for instance and version for modl

   Sebastian: (loos into Issue 1000)
   ... example of Eclipse Vorto model

   <Ege>
   [25]https://github.com/w3c/wot-thing-description/issues/947

     [25] https://github.com/w3c/wot-thing-description/issues/947

   [26]Issue 1000

     [26] https://github.com/w3c/wot-thing-description/issues/1000

   Sebastian: would it make sense to add "model" term to
   "version"?

   McCool: another possibility is that Thing Model's version
   number simply refers to the version of the Thing Model
   specification

   Lagally: would be confusing

   McCool: that's true

   Sebastian: what should we do then?

   McCool: for Thing Model, should only have "model"
   ... without link

   Sebastian: ok

   "version" : {"model" : "1.0.0"},

   Sebastian: let's quickly do that
   ... (reusing the "version" container, skip `instance` nd
   introduce a new term `model`)
   ... (adds an updated example to Issue 1000)

   McCool: we could think about DID here

   [27]Sebastian's latest comment

     [27] https://github.com/w3c/wot-thing-description/issues/999#issuecomment-733805049

   version definition for the model:

   "version" : {"model" : "1.0.0" },

   version definition for the instance:

   "version" : {"instance": "1.0.0",

   "model" : "1.0.0" },

   "links" : [{

   "rel" : "instanceOf",

   "href" : "<address of the TM model>"

   }],

Issue 1003

   [28]Issue 1003

     [28] https://github.com/w3c/wot-thing-description/issues/1003

   [29]table within section "5.4 Default Value Definitions"

     [29] https://w3c.github.io/wot-thing-description/#x5-4-default-value-definitions

   Kaz: note there is "5.4" twice within the section title

   Sebastian: right
   ... (creates an issue on that)
   ... regarding the issue 1003 itself, would it make sense to
   have more detailed description on op?

   (no objections)

   Sebastian: Ege, can you create a PR for this?

   Ege: ok

Issue 983

   [31]Issue 983

     [31] https://github.com/w3c/wot-thing-description/issues/983

   Sebastian: there is actually a section for Multilanguage
   ([32]https://www.w3.org/TR/wot-thing-description11/#multilangua
   ge)
   ... (adds a comment)

     [32] https://www.w3.org/TR/wot-thing-description11/#multilanguage)

   [33]Sebastian's comment

     [33] https://github.com/w3c/wot-thing-description/issues/983#issuecomment-733812960

Issue 977

   [34]Issue 977

     [34] https://github.com/w3c/wot-thing-description/issues/977

   Sebastian: the IP address where the TD comes from

   McCool: model is meant to be more abstract
   ... directory entry for discovery needed

   Ege: IP address possibly changes based on the environment for
   mobile usage, etc.

   McCool: maybe you could describe the device itself
   ... would suggest we write up a use case for that

   Kaz: agree we should generate a use case description about this
   ... related to how to deal with session lifecycle

   McCool: two possible issues
   ... no IP address
   ... and change of IP address

   Kaz: no IP address specification for Thing Model may imply
   dynamic address assignment
   ... there are several possible settings

   [35]updated comment

     [35] https://github.com/w3c/wot-thing-description/issues/977#issuecomment-733824110

Issue 1005

   [36]Issue 1005

     [36] https://github.com/w3c/wot-thing-description/issues/1005

   Sebastian: some of the combinations should be prohibited
   ... e.g., both readOnly and writeOnly as "true"

   McCool: maybe JSONSchema guys know how to avoid it

   Koster: should be compatible with oneDM

   McCool: readable/writable would be clearer

   Sebastian: (adds Henry Andrews for JSON Schema and Mchael
   Koster for SDF)
