What areas in implementation of information exchanges does GRA address?

The Global Reference Architecture (GRA) addresses various areas in the implementation of information exchange. Together, these areas form critical components of a comprehensive, replicable, and scalable solution to information sharing that balances varied technologies with dynamic policy considerations:

Reference Architecture Planning
The GRA includes recommendations for technical implementation that leverage Service Oriented Architecture concepts, customized for the justice domain. GRA addresses the full range of information sharing use cases by providing a flexible blueprint for implementing interoperable data sharing services across both technologically advanced organizations and those with limited technology resources. Guidelines for beginning implementation projects are available.

Service Specification Packages
GRA solutions to information exchange are made up of a combination of the connection method (often Web Services), the exchange language (use of NIEM is encouraged), and the security specifications (encryption at the transport layer, data layer, etc.). These specifications are packaged into a GRA solution that can be customized to meet an individual organization’s needs. A repository of Reference Service Specification Packages (SSPs) for information exchange in the justice community is being established; however, individual Reference SSPs are available in the interim.

Technical Implementation Guidance
Integrating a Reference Service Specifications Package (SSP) into existing IT infrastructure, despite the level of customization available in a Reference SSP, can involve a learning curve for those new to the implementation of GRA. Technical guidance regarding the GRA specification itself, as well as various guides on the interaction of different services and other aspects of information exchange, are available. In addition, personal assistance in implementing GRA is available through a number of valuable resources. See the Implementation Assistance section for more information.

Policy Guidance
In coordination with the technical implementation of a GRA Reference Service Specification Package, policy-level documents guide interaction between the agencies exchanging information. Examples include Service Level Agreements (SLA), access and identity management specifications, Memoranda of Understanding (MOUs), and many others. While these documents are never specific to GRA implementations, some specific resources available may be helpful in policy agreements.                                                                                                                                                                                                                                                                                        Source:
