Hi! We’re the Solid Community Group (CG) of the W3C. The purpose of this document is to help readers orient themselves with the activities of the Solid CG.

The CG has a charter.

The Solid CG’s technical reports (TR) include specifications, use cases and requirements, best practices and guidelines, primers and notes about the Solid ecosystem.

Work Items

The aims of the Solid project are in line with those of the Web itself: empowerment towards an equitable, informed and interconnected society. Solid adds to existing Web standards to realise a space where individuals can maintain their autonomy, control their data and privacy, and choose applications and services to fulfil their needs.

The information in these documents may be subject to change, therefore please see each document’s publication status and versions for further details. You are invited to contribute any feedback, comments, or questions you might have.

Notification Channel Type Registry

In order to help with the discovery of notification channel types that can be used with the Solid Notifications Protocol, it is encouraged to register them for maximum global interoperability.

To update the registry table an implementer MUST submit a modification request for this index as a pull request at the repository, which includes the following information:

The URL of the document that specifies the notification channel type.
The name of the notification channel type.
The IRI of the notification channel type.
A short English description of the notification channel type.
