Data Standards

The National Standards programme will address the lack of data standards currently in place to govern the design, integration and interfacing of applications and data throughout the police service in England and Wales.

The National Standards Programme will work closely with industry to baseline the existing data models across the police service and promote data exchange across policing and the wider Criminal Justice System.

The new data standards will, where appropriate, incorporate semantic and structural design from previous policing standards such as CorDM, the Police National Data base (PND), international and industry standards, and standards and interface definitions published by partner organisations eg within the Criminal Justice System.

Cor DM

The National Policing Improvement Agency (NPIA) developed the Police Corporate Data Model (CorDM) and associated Corporate XML (CorXML), which were key components of its Information Systems Strategy for the Police Service (ISS4PS) and Information Systems Improvement Strategy (ISIS) programmes.  CorDM and CorXML became obsolete on the closure of the NPIA and the websites were removed.

The Police National Database (PND) created updategram formats which describe the format in which forces need to provide information to be uploaded to PND. These formats are based on the structure of PND rather than representing a canonical format.

CorDM included Listpoint, which remains in use.

Information Systems Strategy for the Police Service (ISS4PS)

The Information Systems Strategy for the Police Service (ISS4PS) was the overarching IS/ICT strategy for the Police Services in England and Wales published by the Police IT Organisation (PITO) around 2006.


The standard was based on the following principles:

  • Service Based
  • Business Services
  • Modularity
  • Service Integration
  • Common Presentation to Users
  • Modern Development Methodologies
  • Open Standards
  • It adopted many aspects of TOGAF including the Standards Information Base. is an online tool providing a repository and mapping service for the use of constrained value lists. It was originally developed by the NPIA, but is now maintained by a commercial organisation. It enables organisations to store constrained value lists used in standards and individual applications and, where relevant, to map values in one constrained value list to the values in another.

It also provides a service which enables registered users to subscribe to changes made to constrained value lists in which they have recorded an interest. Constrained value lists which are part of CorDM and PND are recorded on Listpoint and it is an integral part of the PND solution since it contains the mappings of constrained value lists used in force source systems to the corresponding constrained value lists in PND.
