National Information Exchange Model (NIEM)
NIEM, the National Information Exchange Model, is a partnership of the U.S. Department of Justice, Department of Homeland Security, and Department of Health and Human Services. It is designed to develop, disseminate and support enterprise-wide information exchange standards and processes that can enable jurisdictions to effectively share critical information in emergency situations, as well as support the day-to-day operations of agencies throughout the nation.
NIEM enables information sharing, focusing on information exchanged among organizations as part of their current or intended business practices. The NIEM exchange development methodology results in a common semantic understanding among participating organizations and data formatted in a semantically consistent manner. NIEM will standardize content (actual data exchange standards), provide tools, and managed processes.
NIEM builds on the demonstrated success of the Global Justice XML Data Model. Stakeholders from relevant communities work together to define critical exchanges, leveraging the successful work of the GJXDM, and further enhancing the capabilities of the NIEM model by developing Information Exchange Package Documentation (IEPD). You can search the latest IEPDs through the NISS IEPD and Justice Standards Clearinghouse, also accessible from the Implementation Assistance section.
