National Information Exchange Model Law and Legal Definition

The National Information Exchange Model (NIEM) is an XML-based information exchange framework of the U.S. The NIEM is maintained through te joint efforts of the U.S. Department of Justice, the U.S. Department of Homeland Security, and the U.S. Department of Health and Human Services. The NIEM is designed to develop, circulate 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 U.S.

The NIEM focuses 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.
