First Public Working Draft: Verifiable Credentials Data Model v2.1

The Verifiable Credentials Working Group published today a First Public Working Draft of Verifiable Credentials Data Model v2.1. A verifiable credential is a specific way to express a set of claims made by an issuer, such as a driver's license or an education certificate. This specification describes the extensible data model for verifiable credentials, how they can be secured from tampering, and a three-party ecosystem for the exchange of these credentials that is composed of issuers, holders, and verifiers. This document also covers a variety of security, privacy, internationalization, and accessibility considerations for ecosystems that use the technologies described in this specification.
