National Information Exchange Model

Part of the Data and data management glossary:

The National Information Exchange Model (NIEM) is an XML-based information exchange framework for sharing data between communities of interest (COIs), across all levels of the United States government. COIs may include law enforcement, the court system, public safety, intelligence, homeland security and emergency and disaster management.

Next Steps

Instead of trying to integrate local, state, tribal and federal databases, NIEM standardizes a semantically consistent information exchange package by providing a common format and language for describing people, places, things & events, as well as the relationships between them.

NIEM is a partnership between the U.S. Department of Justice and the U.S. Department of Homeland Security. It is built on an exchange framework developed earlier for the criminal justice community called the Global Justice XML Data Model.
