National Information Exchange Model (NIEM)

The National Information Exchange Model (NIEM) is a common vocabulary that enables efficient information exchange across diverse public and private organizations. NIEM connects communities of people who share a common need to exchange information in order to advance their mission.

NIEM is something like a dictionary of agreed-upon terms, definitions, relationships, and formats that are independent of how information is stored in individual systems. The NIEM model includes community-specific elements, as well as core elements that are commonly agreed to by the communities who use NIEM. Most importantly, NIEM is a foundation to build information exchanges.

The NIEM community includes members from federal, state, local, tribal, private, and international organizations. This active community of users contribute to model content, provide technical assistance and guidance, and offer assets that can be reused to make the development of exchanges faster.

NIEM Website

The NIEM website (http://www.niem.gov ) is the focal point for all things NIEM-related. Here you will find news, technical information, training information, and reference materials to help you manage within the NIEM environment.

National Information Sharing Standards Clearinghouse

The National Information Sharing Standards (NISS) Information Exchange Package Documentation (IEPD) and Justice Standards Clearinghouse provides information on a variety of IEPDs and Justice Standards that have been submitted by individuals and organizations who have implemented the Global Justice XML Data Model (Global JXDM) and the National Information Exchange Model (NIEM). The site also will assist users in finding answers to their technical questions regarding the content, principles, and best practices for using the Global Justice XML Data Model (GJXDM), the National Information Exchange Model (NIEM), Global Reference Architecture (GRA), and Global Federated Identity and Privilege Management (GFIPM).

Global Standards Package

To achieve the interoperability and cost-saving aims of the Global Standards Council, the Global Standards Package (GSP) was developed. The GSP is a collection of normative, independently versioned standards that are assembled into a package of composable, interoperable solutions specifically supporting the exchange of justice information.

The GSP is composed of the following primary components:

  • National Information Exchange Model: https://www.niem.gov/.
  • Global Reference Architecture (GRA): The GRA offers guidance on the design, specification, and implementation of services and related infrastructure for organizations that are looking for an architectural solution to sharing information through external exchanges and common messaging standards between information sharing systems.
  • Global Service Specification Packages (SSPs): Reference services that serve as the means by which the information needs of a consumer are connected with the information capabilities of an information provider. Developers, architects, and service authors are strongly encouraged to refer to the following namespace site when developing Global service specifications. This namespace provides a collection of names, identified by uniform resource identifiers (URIs), which are used to support GRA service specifications, service specification artifacts, packaging metadata, and sample documents.
  • Global Federated Identity and Privilege Management (GFIPM): The GFIPM specifications and guidelines are designed to support security controls when accessing justice information systems, based on commonly understood and applied user access control policies. 
  • Global Privacy Technology Framework : The technical privacy framework is a methodology and series of tools designed to support defining the data privacy and confidentiality rules and disclosure obligations based on various roles and conditions.
