AddressBase is structured as a flat file. The data structure in this document is described by means of Unified Modeling Language (UML) class diagrams.
The AddressBase product is constructed as per the following UML diagrams.
Definition: This address record follows the lifecycle of a Postcode Address File (PAF) record matched to a Local Authority record. As a matched record is inserted, deleted and updated within PAF, these changes are incorporated into the AddressBase product. Similarly, if the matched Local Authority address record updates an attribute contained within the AddressBase product, this change will be reflected.
The UML model of AddressBase in CSV format can be seen in the UML diagram below; classes from the Ordnance Survey product specification are coloured orange; all code lists are coloured blue, while enumerations are coloured green.
