Preliminaries

   Johannes discussed agenda

   Johannes: are there additions

Discussion on scope definition and outputs of the Task force

   Johannes: discussion of the scope and output of the TF

   In the wiki is a first draft of the scope

   <kaz> [9]draft scope on wiki

      [9] https://www.w3.org/WoT/IG/wiki/APIs_and_Protocols_TF#Task_force_on_APIs_and_Protocols

   Johannes: determine a set of common primitives for interactions

   how do those primitives map to protocols and API

   the APIcan be used to expose and consume things

Presentation from Nimura-san on UC and Architecture

   <kaz> [10]Nimura-san's slides

     [10] https://lists.w3.org/Archives/Public/public-wot-ig/2015May/att-0022/A_use_case_and_architecture__Fujitsu_.pdf

   Use Case: house calls by caregivers

   [page 2: An architecture]

   Joerg: how to bind the device driver with the IoT device

   Nimura-san: is not described here, might be an issue for the
   discovery, might use MAC

   Johannes: is the protocol between the WoT device and the WoT
   Server and the one to the device driver the same

   Nimura-san: the interface between GW and WoT server might be
   inside a smart phone
   ... in focus is how to migrate IoT devices such as thse
   connected via bluetooth and provide a driver for this

   <inserted> scribenick: kaz

   kaz: would suggest we should be very careful to distinguish the
   hardware layer and the software layer
   ... the "gateway" here should be called "wot adapter" or
   something like that
   ... and could be installed on the smartphone or the IoT device
   or even on some cloud service

   [page 3: Setup]

   <scribe> scribenick: Joerg

   the smartphone can request the apropriate driver for the IOT

   distribute the driver to the gateway

   and register the device with the WoT Server

   <kaz> scribenick: kaz

   kaz: we can reuse existing discovery mechanism like bonjour.
   right?

   nimura: yes

   jhund: good input for the discovery group

Contribution from Johannes Hund, Siemens - Sketch for a document
extracting commonalities in the proposals, i.e. the interactions and
mappings to APIs and protocols

   [audio connection dropped, and everybody switches to webex]

   <kaz> [11]Initial sketch on abstract interactions for APIs and
   Protocol bindings

     [11] https://github.com/w3c/wot/blob/master/TF-AP/Example_sketch.md

   jhund: scripting API mappings
   ... anybody can give input to this document
   ... as the output of this task force

   <kaz> [12]http://www.w3.org/TR/mmi-arch/ MMI Architecture

     [12] http://www.w3.org/TR/mmi-arch/

   kaz: there is an abstracted layer interface definition within
   W3C named MMI Architecture, which could be included in this
   initial sketch document

   jhund: can you talk with the mmi wg and ask them to contribute
   to this protocol mapping document?

   kaz: will do

   Joerg: we have several different architecture designs

   jhund: having concrete graphical representations would be
   useful

   +1

   jhund: any good tool for graphical representations?

   kaz: myself simply use Inkscape :)

   jhund: is the output file an svg?

   kaz: yes, and we can get a png version as well

   <kaz> scribenick: Joerg

   Johannes: PlantUML can be edited textually

   <kaz> [13]PlantUML site

     [13] http://plantuml.sourceforge.net/

   <kaz> scribenick: kaz

   taki: is that freely available?

   Johannes: yes

   taki: we can try several possible tools, and then make decision
   which to use

aob

   Joerg: would think about time slots for TF calls
   ... we have three TFs
   ... maybe it would be better for Kaz to manage the WebEx
   sessions. I'll send the call details to you.

   kaz: ok. I'll talk with the systeam, and will do so if it's
   possible

   <kaz> scribenick: jhund

   Joerg: we will have three time slots each Wednesday on fixed
   recurring slots, with the TF's rotating.
