Notification of Epoch 109’s Improvement in Historic BLPU State Code Completeness and Large Release Size
Summary
The release will enhance clarity and consistency of lifecycle representation within product.
A conformance improvement has been delivered for BLPU State attribute for records where the BLPU Logical Status was 8 (historic) and BLPU State was null; for increased completeness, BLPU State Code has been populated with value 4 (no longer existing) and date stamped for the change applied.
Issue description
The BLPU state identifies the current lifecycle stage of a property (or object) and is additional to the mandatory LOGICAL_ STATUS field.
The BLPU code is an optional attribute for Local Authority Custodians to complete and therefore this attribute may be NULL in product.
An improvement to the completeness of the BLPU State Code was identified as a quality enhancement for lifecycle information as values for BLPU state code 4 can be accurately inferred from a Logical Status of 8. This enhancement allows the data to be interpreted more easily by removing conflict between addresses with a historic logical status and no BLPU state.
All nations within GB and the Islands product regions will benefit from this improvement, as such it impacts approximately 1.2 million records for a Full Supply.
Impact
This quality improvement will be delivered in the next release, Epoch 109, and will mean a larger than usual supply of changes.
No special action will be required to load the release differently.
Next release
The next release of AddressBase Islands products, Epoch 109, is scheduled for Tuesday 05 April 2024.
