This linking dataset allows users to join up information in other Data First justice datasets. It does not itself contain information about people or their justice system interactions but acts as a lookup to identify which records in separate datasets refer to the same people. The MOJ Data First datasets currently covered are:

• magistrates' court defendant
• Crown Court defendant
• prisoner custodial journey
• probation
• family court
• civil court • offender assessments

This linking dataset allows users to join up information in other Data First justice datasets. It does not itself contain information about people or their justice system interactions but acts as a lookup to identify which records in separate datasets refer to the same people.

XJS Link file - This linking dataset allows users to join up information about people in Data First cross-justice system datasets. It acts as a lookup to identify which records in separate datasets refer to the same people.

Mags Crown Journey file - This linking dataset allows users to join up information about people in Data First cross-justice system datasets. It acts as a lookup to identify which records in separate datasets refer to the same people. This linking dataset allows users to join up information about cases in Data First magistrates' courts and Crown Court datasets.
