Background
8.1.1
Application Cross References do the following things:
- Provide additional information indicating the source of a Record entered into an LLPG.
- Confirm data integrity by showing which datasets have been successfully matched to a given Record.
- Show that a Record is matched to an entry in another dataset if the description is not identical.
- Show that the original source of a Record is the SNN Authority.
8.1.2
When the UPRN is integrated into matched additional datasets the requirement for maintenance of a cross reference table will substantially diminish.
