WG WoT Profile WebConf

From Web of Things Interest Group

The WoT Profile task force is responsible for interoperability profiles for the Web of Things.

WebConf Information

This is a call of the WoT Working Group (WG).

Normative Deliverable

WoT Profiles

"The WoT Profiles specification defines a Profiling Mechanism and a set of Profiles which enable out-of-the-box interoperability between Web Things and their Consumers on the Web of Things.

Being out-of-the-box interoperable means that any Consumer which conforms with a given Profile can interact with any Thing which conforms with the same profile, without additional customization.

A Profile is a technical specification which provides a set of assertions to which conformant Consumers and Things must conform.

The Profiling Mechanism provides a means to denote that a given Thing conforms to one or more Profiles, by referring to the identifiers of those Profiles in the profile member of its Thing Description."

1.0 Issue Triage

Questions for each issue:

  • Should this still block 1.0 if published as a Working Group Note?
  • Who is responsible for next steps?

Action Items

Over the next two weeks:

  • Continue to review existing issues to identify any that should block publication as a Note and ensure they are assigned to someone
  • Encourage a full review of the current Profiles specification to identify any other issues which should block publication as a Note
  • Start to work on Profile-1.0 issues as assigned

Future Meetings

  • Next meeting two weeks from now (11th June)
  • Meetings every two weeks

(In the meantime, see you on GitHub and Discord)

Working Group Note Resolution

W3C Working Group Note Publication Process

The Note Track

Summary:

  • A Group Note (NOTE) is published to provide a stable reference for a useful document that is not intended to be a formal standard.
  • There are few formal requirements to publish a document as a Note or Draft Note, and they have no standing as a recommendation of W3C but are simply documents preserved for historical reference.
  • The group:
    • MUST record their decision to request publication as a Note or Draft Note, and
    • SHOULD publish documentation of significant changes to the technical report since any previous publication.

Question:

  • Should we publish a Draft Note before publishing a Note (by July), or is the last Working Draft sufficient?

1.0 Issue Triage

Questions for each issue:

  • Should this still block 1.0 if published as a Working Group Note?
  • Who is responsible for next steps?

Action Items

Over the next two weeks:

  • Continue to review existing issues to identify any that should block publication as a Note and ensure they are assigned to someone
  • Encourage a full review of the current Profiles specification to identify any other issues which should block publication as a Note
  • Start to work on Profile-1.0 issues as assigned

Future Meetings

  • Next meeting two weeks from now (28th May)
  • Meetings every two weeks

Profiles philosophy

  • Protocol Bindings extend the Thing Description, Profiles restrict/constrain it.

Use Case Task Force requests

  • Which are the Use Cases for profiles?

Past minutes

Profiles as Ecosystem descriptors

  • Continue the last meeting discussion
  • Profiles were mainly focused on Greenfield implementations, but they have an importance for Brownfield as well.
  • An Ecosystem covers more than what a single binding protocol does
    • It could include provisions for Discovery, Onboarding, Data Representation

Use Case Task Force requests

  • The UC TF asks to use the new form to model our Use Cases
