Service Specifications support the two (2) primary use cases of the GRA, which are:
1. To provide the justice information sharing community with an architecture and supporting specifications and guidance such that practitioners can implement SOA more efficiently. As such, the JRA and related documents provide an 80 percent solution that eliminates the need for individual justice practitioners to invent their SOA solutions from scratch and enhances the likelihood of reuse.
2. To provide a framework within which the JRA can be maintained and enhanced and national reference services can be developed to enhance interoperability.
