| Draft as of 2026-03-24 | *Computable Name*:CustodianAssignedUrnIdentifier |

 
Data objects are identified by an 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.
