Notification of Epoch 109’s Improvement in Historic BLPU State Code Completeness and Large Release Size
Summary
This release includes an enhancement in the clarity and consistency of life cycle 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 life cycle 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 life cycle 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 means a larger than usual supply of COUs.
Next Release
The next release of AddressBase Islands products, Epoch 110, is scheduled for Thursday 16th May 024.
