The 'golden copy' is the official, master version of a record.
There can only be one golden copy of each record.
A golden copy exists from the point of creation of a record not just once the record is no longer used.
It is important to remember that the golden copy of a record exists for all stages of its development. Therefore during the early stages of a records development the golden copy may be a draft.
When a record is superseded by an updated version a golden copy may still exist for the previous version, for example with assessment regulations which are updated every year, it is not just the current regulations which have a golden copy - a golden copy should exist for each previous set of regulations, and there will also be a golden copy of the draft of the next year's regulations.
