Scope
Which objects, identities, communications, products or events may be authenticated.
Authentication event
The action that creates the PAR reference and records the relevant evidentiary metadata.
Actor and authority
How the person or organization performing the action is represented and, where relevant, authorized.
Object identity
How the authenticated digital item or claim is distinguished from other items.
Time and event metadata
Timestamp and any permitted contextual metadata connected to the authentication event.
PAR reference
The reference generated so the authentication can later be checked.
Status changes
How revocation, reporting, expiration or other status changes should be represented.
Limitations
Authentication proves the recorded event and evidence within scope; it should not be described as proving facts outside that scope.
