3.7.1
Each LLPG must derive its Street Name and Address Change Intelligence from official SNN Authority processes.
3.7.2
Other Address Change Intelligence should be introduced from other local authority statutory functions that affect Streets within the LLPG. Some examples of these functions are:
- Building Control.
- Development Control.
- Land Charges.
3.7.3
Street Naming functions, planning development control and building control are not statutory duties of some LHAs.
3.7.4
In a ‘two-tier’ structure of County and District Councils, these functions are the responsibility of the SNN Authority.
3.7.5
In these circumstances, all parties involved should establish effective relationships between organisations and find a way to transfer change intelligence electronically.
3.7.6
For diagrams indicating the data flows associated with these processes, see Appendix G.
3.7.7
Except for the entry date, as a minimum, if a Street is entered in both the LSG and the LLPG, then the populated attributes which are associated with that Street must be identical in both the LSG and the LLPG.
3.7.8
The entry date Field must show the true entry date of the Street in each gazetteer, therefore it may be different depending on the information exchange process which is in place.
3.7.9
The locality and town data contained in the LLPG (descriptive identifier) must not be based on postal localities and post towns as defined by Royal Mail. Geographic identifiers should be used.
3.7.10
Geographic identifiers and real world locations in common use should be used to define the location of the Street.
3.7.11
Frequently the adopted postal geography is the same as the derived real world geography.
3.7.12
Each SNN Authority must have a designated Authority Address Custodian who has sole responsibility for the maintenance and content of the LLPG.
3.7.13
Having a designated Authority Address Custodian ensures that a single source controls the addition, archiving and changing of all data in the LLPG.
3.7.14
A consistent approach should then be adopted for all address entries within the LLPG for the SNN Authority administrative area.
3.7.15
Names of individual persons must not be present in any Fields, unless it forms part of an Official Address.
3.7.16
Data taken from third party sources must not be present in any Fields.
