Welcome to the Justice Information Network
The JIN program has successfully developed and employed technologies, policies, and standards to establish and support connectivity among its stakeholders to achieve the goal and objectives for integrating justice information. This combination provides the means for legacy information systems to communicate among each other in a more efficient and cost effective manner. The JIN Program adheres to the following design principles to guide the development of justice integration projects:
- Standards - JIN constituents should utilize adopted national, state, and open industry data and exchange standards wherever possible.
- Interoperability - New applications should focus on interoperability with the JIN infrastructure and data sharing as part of the design process.
- Shared Infrastructure - The JIN community will use shared infrastructure appropriately and leverage existing infrastructure to the fullest extent possible.
- Security and Privacy - Security and privacy are the shared responsibility of all participating stakeholders. Disclosure of data is the responsibility of the data owner according to applicable laws and regulations.
- Applications and Data Exchanges - Applications that exchange data via the JINDEX should be designed or enhanced to be compatible with the JIN standards and policies.
- Reusable Components - Applications should use common, reusable components, data, and designs wherever possible.
- Business Continuity - Applications should mitigate risks, account for dependencies among systems, and capitalize on the economies of scale.
Specifically, the JIN Program utilizes the Global Justice Data Model (GJXDM) and the (3.2) National Information Exchange Model (NIEM) for standardized data definitions and structures. These national data models are intentionally massive and contain thousands of data elements.
Recognizing the need to subset these models, the JIN Program, provided best practices from integrated justice programs resulting in a series of protocols deemed the most effective and widely adopted method for using GJXDM and NIEM. This collective process is referred to as the Information Exchange Package Documentation Guidelines (IEPD). Briefly, this includes:
- Identification of the exchange partners.
- Data elements identified by business users in business terms.
- Data elements are translated into GJXDM data definitions, or identified as extensions by business participants.
- Data elements are organized into a set of XML schemas by technical participants.
