Call for Participation in Web Thing Protocol Community Group

The Web Thing Protocol Community Group has been launched:

The mission of this group is to define a common protocol for communicating with connected devices over the web, to enable ad-hoc interoperability on the Web of Things.

Deliverables of the group may include use cases, requirements and specifications.

The group will collaborate with the W3C Web of Things Interest Group and Working Group to ensure any specifications complement or extend the “Web of Things (WoT) Thing Description” specification.


  1. Define a WebSocket sub-protocol for the Web of Things, using the W3C “Web of Things (WoT) Thing Description” data model and operations
  2. Define an HTTP protocol binding for the Web of Things (or support the Web of Things Working Group in defining this protocol binding and ensuring consistency with the WebSocket sub-protocol where appropriate)
  3. Evaluate other potential Web of Things protocol bindings (e.g. CoAP)

See the proposed Community Group Charter for more information.

In order to join the group, you will need a W3C account. Please note, however, that W3C Membership is not required to join a Community Group.

This is a community initiative. This group was originally proposed on 2019-09-16 by Ben Francis. The following people supported its creation: Ben Francis, Gustavo Zapico, Junde Yhi, Zoltan Kis, Dave Raggett. W3C’s hosting of this group does not imply endorsement of the activities.

The group must now choose a chair. Read more about how to get started in a new group and good practice for running a group.

We invite you to share news of this new group in social media and other channels.

If you believe that there is an issue with this group that requires the attention of the W3C staff, please email us at

Thank you,
W3C Community Development Team
