| Active as of 2026-10-30 | Computable Name: CustodianAssignedIdentifier | ||||
An (unique) identifier that was assigned by the original custodian. The custodian is 'The entity that is accountable for maintaining a true an accurate copy of the original record'. I.e. this custodian is responsible for the 'single source of truth' for this data object. The 'custodian-assigned-identifier' is the unambiguous and persistent identifier for both the data object and the custodian.
