Virtual f2f planning

   [19]Lagally's slides

     [19] https://github.com/w3c/wot-architecture/blob/master/proposals/WoT Use Cases - Next steps-200514.pdf

   Lagally: (introducing use case slides)
   ... We are working use cases and life cycle. Still other work
   items remain.
   ... Workflow for architecture process.

   Kaz: "architecture process" should be "discussion process".

   Lagally: (updated)
   ... Currently there are 20 use cases.
   ... Use case categories: Retail, Audio/Video ...
   ... from use case, we'll prepare a shortlist to make sure the
   use cases address real market needs, etc.
   ... ... then, prioritize them.

   Ege: I support this process.

   Lagally: I'll present this slides in next few meeting.

   Kaz: I suggest that we put a document together including all
   the proposed use cases, then after prioritize them.
   ... I can generate a W3C WBS questionnaire for the voting
   purpose

   Ryuichi: I want to insert "system configuration" between
   "shortlist" and "New Building block" .

   Kaz: "system configuration" may already included in
   "Requirement"
   ... and "Use case" part.

   Ryuichi: to understand "building block", we have to show some
   "system
   ... configuration"

   Kaz: how about remove "new building block", and just discuss
   them in "Gaps"?
   ... we should clarify output of each process.

   Lagally: (categorizing processes to two phase)

   <kaz> [20]strategy funnel

     [20] https://github.com/w3c/strategy/projects/2

   Kaz: W3c teams also have similar process, strategy funnel.
   ... need not to follow the strategy funnel.
   ... Gaps, New BB, Sys Conf are part of "Requirements" as its
   features

Use case

   (issue #496)

   Ege: Educational use cases.

   <kaz> [21]Issue 496

     [21] https://github.com/w3c/wot-architecture/issues/496

   Ege: We put the some device in the lab, and it can be seen by
   IP cameras.
   ... Target users are university student, and plugfest
   participant..
   ... motivation of this use case is device sharing.
   ... (introducing devices, data)

   Kaz: You can make a title more specific. "Sharing devices" etc.

   Lagally: It is not restricted to education.
   ... let's continue discussion in afternoon session.
   ... We have 8 PRs, and we'll review in todays call.

   Ryuichi: I added some use case in Issue. I'll convert it to a
   PR.

Use cases

   Lagally: the Use Cases call was useful, we got inputs

   Lagally presents the Use Case TF presentation

   Lagally: Use Case call will start regularly
   ... a Use Case document will be produced
   ... the Architecture TF takes use cases, identifies
   requirements and feeds them to the other task forces, like TD,
   Scripting, Security, etc

   McCool: regarding the work items we should identify which use
   cases impact them

   Lagally: yes, I am going through the use cases and check how
   they apply

   Lagally: there are about 20 use cases in the pipeline
   ... in various Use Case categories

   McCool: some of these are domains, others are technical
   features, so we should separate them
   ... we should add Transportation and Discovery

   Lagally: we will update this

   <McCool> added 2h slot request to June F2F schedule:
   [23]https://www.w3.org/WoT/IG/wiki/F2F_meeting,_1-12_June_2020,
   _Online#F2F_Topics_.28Tentative.29

     [23] https://www.w3.org/WoT/IG/wiki/F2F_meeting,_1-12_June_2020,_Online#F2F_Topics_.28Tentative.29

   Lagally: how to prioritize use cases

   McCool: we need a champion for each use case
   ... also, a customer and products

   Lagally: requirement documents are one-pagers
   ... based on a template

   <McCool> McCool: think at the end we should wrap things up with
   a use-case/requirements table

   <McCool> ... would give a useful visual summary; can happen at
   the end

   Lagally: the output is a Group Note
   ... there is a problem that people could not access diagrams
   since the lack of a google account
   ... we should store in the repo the contributions

   McCool: a problem is which is the master version for
   multiformat documents

Pull requests

   Lagally: Transportation use case
   ... a kind of overview, let's just go ahead and merge it

   <kaz> [24]Pullrequest 470

     [24] https://github.com/w3c/wot-architecture/pull/470

   Zoltan: I went a circle around separating into categories and
   then realized it makes more sense to have it in one file
   ... we can take it from here

   <kaz> [25]Pullrequest 487

     [25] https://github.com/w3c/wot-architecture/pull/487

   Lagally: let's keep this open, needs discussion

   McCool: this is a technical feature use case

   Lagally: Update Readme, #499

   [28]https://github.com/w3c/wot-architecture/pull/499

     [28] https://github.com/w3c/wot-architecture/pull/499

   updated

   McCool: OK
   ... created a PR for Security & Privacy, asked for review, now
   there is a conflict

   Lagally: Update retail.md, #501

   [29]https://github.com/w3c/wot-architecture/pull/501

   [30]https://github.com/w3c/wot-architecture/pull/502

     [30] https://github.com/w3c/wot-architecture/pull/502

   Lagally: presented by Ege this morning

   Lagally presents the PR

   scribe: it's about education and shared resources

   McCool: there is a gap, question is do we need it?
   ... we could merge it but needs further discussions
   ... also wrt Discovery
   ... not clear if the context is research or education

   Lagally: it's not a problem, can be generalized
   ... will merge it and then discuss

   [merged]

Lifecycle

   <mlagally>
   [31]https://github.com/w3c/wot-architecture/issues/479

     [31] https://github.com/w3c/wot-architecture/issues/479

   Lagally: #478

   [32]https://github.com/w3c/wot-architecture/pull/478

     [32] https://github.com/w3c/wot-architecture/pull/478

   Zoltan: it has been reviewed by Clerley and small things were
   fixed
   ... now in pretty good shape for a proposal (just an input)
   ... the diagram has also been reviewed, again small things
   fixed

   McCool: security review should be still open
   ... and we can merge this PR

   Lagally: I made a few comments on the text
   ... confused about a couple of terms

   <McCool> mm: we should note that not all transitions may be
   valid in all protocols

   Zoltan: right, we are just describing existing protocols

   <McCool> ... for example, not all protocols may allow revision
   to a "manufactured" state: some may only be provisioned once
   and then the key store is "locked"

   Lagally: confused about the "native" word

   Zoltan: it means the underlying protocol for WoT
   ... I could change that
   ... we could also use "non-WoT" instead of native

   Lagally: we could take it in for now and we could improve it
   later

   [merged]

   Lagally: will continue later

   Zoltan: next Thursday is public holiday

   Lagally: ok, need to reschedule

   AOB?
