Wednesday 22 April 2015


  • F2F planning
    • Agree on need for mid-year F2F, preference for July 7-9 or else last week in July (Alan Bird took action to find a host)
    • A subset of us will also plan to attend meeting at Prague IETF (July 18-19)
  • Deliverables:
    • Use cases & requirements
    • Web of things framework (architecture and relation to other work)
    • Security & privacy
  • Teleconferences and working practices
  • Break out sessions slot2:
  • Wrap up


  • We plan to have a July face to face in North America, most likely in California along with an open day
  • We plan to have a joint meeting with the IETF in Prague in mid-July (IETF upcoming meetings)
  • We plan to meet in Japan during TPAC 2015 26-30 October 2015
    • Some of us may stay on for the IETF meeting in Yokohama, the following week
  • We agreed to organise work in a limited numbers of groups and in line with the planned deliverables
    • Use cases
      • To evaluate if the currently taken approach supports the WoT Framework discussion a first use case document shall be compiled based on the use cases submitted so far
      • We decided to make use of a GitHub setup presented by Johannes
      • Compilation of initial use case document: Johannes Hund, Souleiman Hasan, Kazuo Kajimoto
    • Web of Things Framework
      • The group discussed to start the WoT Framework discussion with the three WoT Framework building blocks Thing Description, Scripting API and Protocol Mapping, Discovery
      • To enable focused discussions on the building blocks, task forces on these three building blocks have been started with the following moderators
        • Thing Description – Sebastian Kaebisch, Dave Ragget
        • Scripting API and Protocol mapping - Kazuo Kajimoto, Johannes Hund
        • Discovery - Soumya Kanti Datta, Dave Raget
      • Further discussion is needed on the scope and whether to split this into several documents
      • Provide an outline of the document
      • Brainstorm on the initial contents
      • Comments and refinements made as contributions to the document
      • Include survey of existing IoT platforms and what is needed to integrate them
      • Regular teleconferences of these three task forces are planned and will be announced by the task forces
    • Security and Privacy

IG Working mode until the next F2F:

  • We agreed that the three WoT Framework building block task forces setup their own telconfs and working modes.
  • By that we reduce the telconfs of the WoT IG to once every 4 weeks. Thus the next call is May 19th, We agreed to shift time by 8h, so that we merge to one telconf which is rotating time wise.
  • Compilation of an initial use case document based on the submitted use cases by the editors and contributors.
  • The security and privacy group contributes to the three WoT Framework building block task forces

We plan to use GitHub for the deliverables. This will be applied for the initial setup of the use case document. We didn't decided yet whether to have one repository per deliverable.

W3C is expecting to switch its teleconference facility over to WebEx in a few weeks time, and this should make it easier to schedule meetings. Meeting materials should be sent to the group list or uploaded to the wiki prior to meetings. This requirement is to ensure that these materials are archived on W3C servers.
