Introduction

This document contains a list of all known Verifiable Credential extensions and their associated specifications.

The Registration Process

Software implementers may find that the existing Verifiable Credentials extensions listed in this repository are not suitable for their use case and may need to add a new method to this registry. Adding a Verifiable Credentials extension to this registry is designed to be a lightweight, community-driven process. In order to add a new method to this registry, an implementer MUST:

  1. Implement at least an experimental version of the Verifiable Credentials extension.
  2. Create a specification describing the new Verifiable Credential extension that is publicly available and intended to be conformant with the Verifiable Credentials specification [[!VC-DATA-MODEL]].
  3. Request that the specification be added to this registry by submitting a Github Pull Request that adds the new method to the list of existing extensions.

Specifications that do not meet these criteria will not be accepted. Old listings which are clearly not being developed, or which fall out of conformance may be removed.

Implementers that would like help or guidance during this process are urged to join the W3C Credentials Community Group and request assistance via the mailing list.
