• National Information Exchange Model (NIEM)

  • The NIEM logo is property of the National Information Exchange Model initiative. For details, see NIEM.gov.
  • The National Information Exchange Model (NIEM) is a Federally-supported initiative that provides a framework and best practices for exchanging information between government agencies. NIEM uses XML as its foundation.

    In 2008, the AAMVA Technical Committee recommended that AAMVA use NIEM as the preferred approach for XML standards. The main consideration in making this recommendation was the Department of Homeland Security (DHS) and Department of Justice (DOJ) grant requirements for NIEM conformance.

    Advantages of Using NIEM

    The NIEM framework can help you to:

    • Bring stakeholders and communities of interest together to identify information sharing requirements in day-to-day operational and emergency situations
    • Develop standards, a common lexicon, and an online repository of information exchange package documents to support information sharing
    • Provide technical tools to support development, discovery, dissemination and re-use of exchange documents
    • Provide training, technical assistance, and implementation support services for enterprise-wide information exchange

    If you are interested in partnering with AAMVA for standards development or implementation, contact AAMVA Enterprise Architecture.

    AAMVA contributes driver and vehicle elements used by the motor vehicle community to NIEM. Whenever AAMVA revises these elements, the revisions are communicated to NIEM to keep the NIEM definitions current.

    AAMVA continues to support the development of NIEM as a member of the Justice XML Standards Task Force, providing subject matter expertise. AAMVA also occasionally participates in development teams which focus on specific business and technical items. AAMVA proposes enhancements to improve the model, resolves issues, and monitors changes to ensure that they do not adversely affect AAMVA applications or standards.

    The National Information Exchange Model (NIEM) replaced the Global Justice XML Data Model (GJXDM), which evolved from two separate efforts that were combined to form one standard. These efforts were element definitions for the International Justice and Public Safety Network (Nlets) and the AAMVA element definitions for driver messages.

    In 2001, AAMVA started developing a standard for driver element definitions and defining the messages based on it. In a separate project, AAMVA worked with Nlets to standardize the elements used in the Nlets driver messages. Nlets decided to implement the standardized messages in XML and use a XML standard being developed by the Global Justice XML Task Force. Rather than have two standards, AAMVA joined the Global Justice XML Standards Task Force and merged standards and elements into the Global Justice XML Data Model (GJXDM).

    As one of the one of the original contributors to GJXDM, AAMVA helped define the model and the processes for its operation and maintenance. The resulting Global Justice XML Data Model (GJXDM) conforms to many XML standards (for example, Federal XML) and XML guidelines (for example, OASIS UBL and ebXML). In 2004, the GJXDM was awarded an American Council for Technology (ACT) Intergovernmental Solutions Award for demonstrating tremendous progress in government collaboration and innovative use of technology.

    As the use of GJXDM broadened, its focus was expanded to cover domains beyond the justice communities. In 2005, this expansion resulted in the publication of the NIEM standard, which replaced GJXDM. Most of the GJXDM definitions were rolled into the NIEM-Core or the NIEM-Justice domains and new domains were added for areas such as Emergency Management.



    NIEM—the National Information Exchange Model—is a community-driven, standards-based approach to exchanging information. Today's challenges and opportunities cut across various sectors and organizations, often requiring collaboration between governments and industry. NIEM brings together diverse communities that collectively leverage tools, processes, and technologies to increase efficiencies and improve decision-making.
