Class: Attestation

An issuer’s judgment, made at a stated time, about what it targets: exact versions of claims, of other attestations, or a snapshot of claims. As a Claim it is attributed (hasClaimant names the issuer), immutable and revisable with wasRevisionOf; it is about a subject, such as a project or a plot, even when it judges a claim about that subject. It does not carry its own hash or IRI, anchoring state, or a status that changes after it is made: a later judgment is a new Attestation.
