2021 - W3C CCG Charter Changes

	W3C Credentials Community Group Charter (2020)


	This charter was ratified by group consensus on [Date]. The previous revision of the Credentials Community Group Charter is also available for archival and auditing purposes.


	The mission of the W3C Credentials Community Group is to explore the creation, storage, presentation, verification, and user control of credentials. We focus on a verifiable credential (a set of claims) created by an issuer about a subject — a person, group, or thing — and seek solutions inclusive of approaches such as: self-sovereign identity; presentation of proofs by the bearer; data minimization; and centralized, federated, and decentralized registry and identity systems. Our tasks include drafting and incubating Internet specifications for further standardization and prototyping and testing reference implementations.
	Scope of Work
	In general, topics that are “in scope” include anything related to enabling interoperable credentials on the Web. These topics include the following:

	PROPOSAL: Existing documentation in the DID Core specification should be refined to point out that Verification Relationships are arcs in a graph of information and Verification Methods are nodes in a graph of information. That is, they provide different types of information. The first (Verification Relationship) is the expression of a relationship between a DID Subject and cryptographic information used for the purposes of verifying a proof. The second (Verification Method) is the expression of cryptographic material. An image should be provided depicting the explanation.

	PROPOSAL: Mark all verification methods with a warning stating that there is an ongoing discussion around the naming of verification methods that may impact the final names used in the specification.

	PROPOSAL: The DID WG urges the W3C CCG to write documentation in the Linked Data Security specifications that clarifies how public / private key terminology has been used in the past, why it is vague and leads to security issues (like key reu
