WG WoT Thing Description WebConf

From Web of Things Interest Group

The WoT Thing Description task force is responsible for defining the information model for WoT Thing metadata, its interpretation, and its common representation. In addition, the task force covers WoT Binding Templates topics to define the mapping from the abstract interaction model used in the Thing Description metadata to concrete IoT protocols and payload encodings.

Wednesdays at 7am US Pacific / 10am US Eastern / 4pm Europe / 10pm China / Midnight Korea & Japan

This is a WoT WG WebConf and underlies the W3C Patent Policy

Call Moderation

The TF is moderated together by Ege Korkan and Michael Koster

  • Koster: Basic architectural design, document structure, etc. Project management (keep people informed on the process)
  • Ege: concrete description based on the design (constructing the statements for normative/informative style for implementability and testability), call moderation
  • Together: Work on how to improve the spec collaboratively, e.g., schedule of the deliverables, and keeping up with the deadlines.
    • We join the calls together unless there is a conflict.
    • Responsibility is not split, it is shared. If someone asks a question, both should be able to answer it.
  • Feedback from the TF:
    • Cris: Testability should be assured
    • Kaz and Koster: TD still does the governance of testing, we are responsible. To be further discussed and the relationship to testing TF clarified.

Zoom

IRC

The IRC is used for the minutes, speaker queue, and sharing links etc.
