NIEMOpen information

NIEMOpen (neemopen), frequently referred to as NIEM, originated as an XML-based information exchange framework from the United States, but has transitioned to an OASIS Open Project. This initiative formalizes NIEM's designation as an official standard in national and international policy and procurement. NIEMOpen's Project Governing Board recently approved the first standard under this new project; the Conformance Targets Attribute Specification (CTAS) Version 3.0. A full collection of NIEMOpen standards are anticipated by end of year 2024.

NIEM offers a common vocabulary that enables effective information exchanges across diverse public and private organizations. NIEM is currently developing the NIEM Metamodel and Common Model Format which can be expressed in any data serialization that NIEM supports, including, but not limited to JSON.

Formed from an interagency partnership, NIEM has come to represent a collaborative partnership of agencies and organizations across all levels of government (federal, state, tribal, and local) in addition to private industry. The purpose of this partnership is to effectively and efficiently share critical information at key decision points throughout the whole of the justice, public safety, emergency and disaster management, intelligence, United States Department of Defense and homeland security enterprise. NIEM is designed to develop, disseminate, and support enterprise-wide information exchange standards and processes that will enable jurisdictions to automate information sharing.

Today, NIEMOpen is sponsored by the Joint Staff J6 Directorate within the U.S. Department of Defense, the Department of Homeland Security Science and Technology Directorate (DHS S"&"T), the FBI Criminal Justice Information Services (CJIS) within the U.S. FBI, Equivant, Georgia Tech Research Institute, the National Association for Justice Information Systems, sFractal Consulting LLC, the IJIS Institute, the US Department of Transportation, and the Virginia Office of Data Governance and Analytics. NIEM provides a working and collaborative partnership among governmental agencies, operational practitioners, systems developers, and standards bodies across Federal, State, Local, Tribal, Territorial, International and Private organizations.

NIEM has been identified as a key enabler for Joint All Domain Command and Control (JADC2). NIEM is cited in the JADC2 Reference Architecture (RA) Version 3.0 Enclosure D (JADC2 Capability Development and Analytical Framework) within the Application and services, Interface and Data & Information principals. JADC2 Reference Design (RD) Version 1.0, Standard View 2 (StdV-2).^[1]

NIEM most recently was referred to as the National Information Exchange Model. That interagency government project was an outgrowth of the United States Department of Justice's Global Justice XML Data Model (GJXDM) project. As an interagency project it was expanded to include other federal and state agencies such as the Office of the Director of National Intelligence, United States Department of Defense, Federal Bureau of Investigation, Texas, Florida, New York, Pennsylvania, and others.
