   <kaz> [16]Accommodation

W3C Data Modesl for Transportation WS

   McCool: can taki attend the workshop for data models

   <kaz> [17]workshop cfp page (12-13 Sep., Palo Alto, US)

     [17] https://www.w3.org/auto/events/data-ws-2019/cfp.html

   Taki: I haven't booked flights so I can attend this workshop
   and fly from there
   ... physically I am ok

   McCool: a proposal together?

   Kaz: like for our workshop, a statement

   Taki: then I can submit today

   <kaz> [18]application form

     [18] https://www.w3.org/2002/09/wbs/1/auto-data-01/

   McCool: summarizing what we have done

IETF 105 Montereal (Jly 20-27) and WISHI/OPC meeting (July 19)

   McCool: there is a wishi meeting and hackathon
   ... michael koster is participating
   ... any other conference that is relevant?

   Koster: friday 19th we are having a meeting with OMA

   <mjkoster> this is the agenda for the IETF T2TRG/OMA meeting on
   Friday the 19th

   <mjkoster> [19]https://github.com/t2trg/2019-07-oma

     [19] https://github.com/t2trg/2019-07-oma

   McCool: I kind of invited myself to that

Old documents

   Daniel: googling td on google shows up an old TD proposal that
   is still marked with a recent date

   Daniel: it is called JSON Web Thing Description

   McCool: this shouldn't even be there, it looks like an official
   document

   Ege: it is not actually published at this date

   Kaz: it's just a date respec generates, isn't it?

   McCool: looks like it

   Daniel: it is in our repo so we can simply remove it

   Kaz: we have to tell the Authors/Editors of those old documents
   gently before removing the documents to remove it

   McCool: maybe we can put in an archive subdirectory

   <kaz> [20]proposal directory

     [20] https://github.com/w3c/wot/tree/master/proposals

   McCool: there are a lot of documents in here

   Kaz: maybe just change the "proposal" folder name to "archive"

   <kaz> [21]old architecture directory

     [21] https://github.com/w3c/wot/tree/master/architecture

   (mm creates a directory called ARCHIVE under proposals)

   Lagally: there is a folder called architecture that should not
   be in the wot main repo

   Koster: I think it is better to keep the folder names but
   simply moving everything under archive

   McCool: (works on cleaning up the main directory)

   Kaz: if it is ok for Lagally, we can move the old
   "architecture" directory under "proposals" first
   ... and then ask all the editors of old documents about if it's
   ok to change the name of "proposals" to "archive"

   <Zakim> dape, you wanted to assign someone to check github for
   outdated information (to put into ARCHIVE folder)

   McCool: writing an email to the list
   ... need to look at what is old, like 2 years

WG Charter Extension

   McCool: 6-month exension to WG has been approved (till Dec 31)

   (Kaz is working on the AC announcement.)

IG Charter under review

   <kaz> [22]Wendy's comment

     [22] https://github.com/w3c/wot/issues/835

   McCool: giving a wiki site for exploration
   ... maybe don't need for clarifications on all the bullet
   points?
   ... some things are intentionally vague?

   <kaz> [23]Proposed IG Charter

     [23] https://w3c.github.io/wot/charters/wot-ig-2019.html

   McCool: (looks at the PRs by wendy)
   ... let's merge the charted PR

   <kaz> (some minor conflict and McCool will look into it later)

   Kaz: we'd like clarification from alan bird

   <kaz> [24]Alan's comment for IG Charter (Member-only)

     [24] https://lists.w3.org/Archives/Member/member-wot-ig/2019Jul/0001.html

   McCool: we have proposed a clear sentence for this comment to
   be added
   ... I will ping him and ask him

TPAC planning

   Kaz: any joint meeting ideas?

   McCool: JSON-LD and accesibility would be good
   ... for Monday, Sep 16 (18:30-22:30)
   ... I can go to dev meetup
   ... other attendees can write their names here but you have to
   register first

Core profile proposal

   Lagally: reviews from companies and individuals show some
   issues
   ... you have now a formal way of describing devices
   ... each time a new class of device comes, we can get
   un-interoperability
   ... so we need profiles that can guarantee usability of the
   device
   ... so we need some constraints
   ... having only one form
   ... having string or array of strings, causes an overhead
   ... constraint on objects, not nested
   ... not permitting security on lower levels, only one at the
   top level
   ... constraints on protocol, having only http

   McCool: what reduces complexity and what reduces
   interoperability
   ... so we should have two categories

   Lagally: so that constrained devices will be easier to support
   ... we can have multiple profiles

   McCool: we can look at the test results and focus on features
   that are implemented by 3+ implementations

   Lagally: but what is there as an example to validate the spec
   and what is an actual product?

   McCool: we can also add to check what uses HTTP or other
   profiles

   Ege: mozilla also talked about having action semantics (a queue
   for running actions etc.) so maybe we should look into specific
   behavior of interactions

   Lagally: interesting point to look into
   ... where would a new implementer find a guide to do a first
   implementation
   ... high level constaints
   ... (talks about the bullet points of the last slide)
   ... I was thinking of specifying a default profile
   ... the proposal is to have a very easy to implement profile
   ... I am working on a list of constraints

   McCool: I would keep it simple

   Lagally: the difficult part would be to define the simple one,
   a complex one is easier to define but something that can
   satisfy 80% use cases

   <Zakim> dape, you wanted to think about ways to identify
   capabablities.. profile handshake?

   Daniel: handshake definition

   McCool: Lagally is proposing the simplest possible
   ... there will be very probably multiple profiles, smart home
   and industrial for example

   Lagally: you can do anything, just that if you stick to the
   core profile you have a guarantee of wider usability

   McCool: we need to clarify what are the allowed extensions

   Lagally: I expect to have a draft within a week

TF reports

   [Thing Description]

   <kaz> [25]Jul-5 TD minutes (member-only)

     [25] https://www.w3.org/2019/07/05-wot-td-minutes.html

   Ege: protocol bindings will be with TD calls and I will be
   co-editor of the spec

   [Archtiecture]

   <kaz> [26]Jul-4 Arch minutes (member-only)

     [26] https://www.w3.org/2019/07/04-wot-arch-minutes.html

   Lagally: architecture - we read the comments of David Baron
   ... device management is out of scope
   ... we had some useful comments
   ... like missing links for the external links
   ... they also didn't understand what will happen if you parse
   JSON or JSON-LD

   <inserted> kaz: note that I sent another reminder to TAG and
   mentioned it might be going to make sense to have a joint call
   with them to clarify their questions.

   McCool: IETF is happening in two weeks

   Lagally: I would organize the call next week then
   ... saying that this would be a deadline for us since the week
   after there will be the IETF meeting

   Kaz: Daniel Applequist, Yves Lafon and David Baron should be
   involved
   ... we should clarify their viewpoints as TAG as a whole

   [Scripting API]

   <kaz> (no call on July 8 but updates from Zoltan)

   scribenick: egekorkan

   Zoltan: so there are some projects that are already using web
   of things
   ... and they need some help

   <zkis> [27]https://www.sofie-iot.eu/

     [27] https://www.sofie-iot.eu/

   McCool: we have extensions
   ... but how do you do in the scripting api

   Zoltan: scripting is orthogonal

   [Security]

   McCool: security is handled out of hand

   Zoltan: in payments it is transparent, it is happening in the
   backend

PlugFest call

   McCool: 5 mins break before the plugfest

   Lagally: let's stay on this call

   <kaz> [adjourned]
