7.3.4.1
An LPI shall have a LOGICAL_STATUS reflecting the current stage that it has reached in its life cycle. Sometimes, this is different from the BLPU’s LOGICAL_STATUS.
7.3.4.2
An Approved Preferred LPI Record (LOGICAL_STATUS=1) shall exist for an Approved BLPU for each language used. This LPI shall reflect the name of the Street providing access to the BLPU, which is not necessarily the Street which is used in the Postal Address.
7.3.4.3
An LPI Record with a LOGICAL_STATUS = 1 shall only be associated with a BLPU Record with a LOGICAL_STATUS = 1. For full details of acceptable LPI and BLPU LOGICAL_STATUS combinations see the table at Section 7.3.4.6.
7.3.4.4
Permitted LPI LOGICAL_STATUS codes are shown below:
1
Approved Preferred
3
Alternative
5
Candidate (reserved for the Candidate process)
6
Provisional
7
Rejected Record (externally sourced reserved for the Candidate process)
8
Historical
9
Rejected Record (internally sourced)
7.3.4.5
More than one LPI for a BLPU must be created in the following cases:
- If there are alternative identifiers or descriptions in common use for the same BLPU.
- In a bilingual gazetteer, if the same address is described in two different languages which are given the same weighting.
- If an LPI is associated with a type 4 or type 9 Street Record.
- If a Provisional LPI exists on an Approved BLPU.
- If a Historical LPI exists on an Approved BLPU.
For more examples, see Section 7.3.4.7.
7.3.4.6
LOGICAL_STATUS is a core attribute of both the LPI and BLPU Record. The relationship between the LOGICAL_STATUS of a BLPU and an LPI must be maintained in accordance with the table below.

1(a), 3, 5(b), 6, 7, 8, 9

Note (a): Multiple Approved Preferred LPIs are only allowed if they have different languages.
Note (b): LOGICAL_STATUS = 5 is reserved for transferring Candidate Records from GeoPlace to the Authority Address Custodian for review.
Note (c): Records with a BLPU_STATE = 5 - Planning application received or 7 – Planning permission refused, must not be submitted to GeoPlace.
Note (d): Please refer to the Life Cycle Guidance and Best Practice Document for permitted BLPU state codes.
7.3.4.7
The following provides some examples of the uses of an Alternative LPI which:
- Must be used if an alternative name is in common use, to aid location of the property. An example of this is “Slab Square” which is a local name for the Old Market Square in Nottingham. The description can also be derived from legacy datasets, but it is not feasible to subject all these Objects to the SNN process retrospectively.
- Should be used if a land parcel is described according to the Streets which are used to access it, for example Clifton Park has a primary access in Summerwood Lane but has a secondary access in Fairham Road. A user can describe either access point, both of which have equal merit, therefore it is appropriate for both descriptions to be represented.
- Should be used for commercial sites such as a hospital or university whose buildings can have a Postal Address on a ‘generic’ Street on the site but whose physical location is accessible from another Street. For example, Lenton Lodge, University of Nottingham, The Boulevard has The Boulevard as the Street Name in the Postal Address but the building is actually accessed from Beeston Lane. In this example, The Boulevard is associated with the Alternative LPI because it provides primary access to the site but not to the building.
- Should be used for commercial properties, for example, shops, which have two entrances from different Streets and their Official Address has never been subject to the official SNN process. In this scenario the Street identified within the Postal Address can differ from the Street which is used to gain access for services.
- Should be used for units within, for example, a shopping centre, if the units themselves are accessed from named Malls within the shopping centre, but the service areas within those units are accessed from an external Street. Both addresses would describe the same unit and therefore the same BLPU, but the Street Name or Description would differ for different users for different purposes. A similar example is a railway station, where pedestrians gain access from a Street, but vehicles gain access from another.
