claim validation (concept) §: Defined in Verifiable Credentials Data Model v2.0: The assurance that a claim from a specific issuer satisfies the business requirements of a verifier for a particular use. This specification defines how verifiers verify verifiable credentials and verifiable presentations.
It also specifies that verifiers validate claims in verifiable credentials before relying on them. However, the means for such validation vary widely and are outside the scope of this specification. It is expected that verifiers will trust certain issuers for certain claims and apply their own rules to determine which claims in which credentials are suitable for use by their systems.
