We're trying to clarify the terminology for the badly named "Web Identity" spec. While this may seem like bikeshedding, clarifying the terminology helps identify what the spec is and isn't about. The newest iteration of the specification abstract looks like this: """ An identity is a Linked Data description of a particular entity such as a person or organization. A credential is a qualification, achievement, quality, or information about an identity's background such as a name, government ID, home address, or university degree. This specification describes mechanisms for reading credentials from and writing credentials to a Linked Data identity while ensuring that the information is only accessible to authorized applications. """ The terminology has changed from "assertion" -> "credential", and from "endorsement" -> "claim. So, identities may contain one or more credentials. Credentials may contain one or more claims about a particular identity. As an example, an identity "https://example.com/i/jane" contains a digitally signed credential supplied by the US Government claiming that the name "Jane Doe" and the government-issued ID "123-45-6789" is associated with the identity: { "@context": "https://w3id.org/identity/v1", "id": "https://example.com/i/jane", "type": "Identity", "name": "Jane Doe", "governmentId": "123-45-6789", "credential": [{ "id": "http://ssa.us.gov/credentials/3732", "type": "PassportCredential", "claim": { "id": "https://example.com/i/jane", "name": "Jane Doe", "governmentId": "123-45-6789" }, "expires": "2018-01-01", "signature": { "type": "GraphSignature2012", "signer": "https://ssa.us.gov/keys/27", "signature": "3780eyfh3q0fhhfi...8ahsidfhf29rhaish" } }, ... ] } This new formulation hints at the real purpose of the specification. It isn't about identity as much as it is about asserting an identity's credentials. In that vein, the specification should probably be renamed from "Web Identity" to "Web Credentials".
