NIEM, the National Information Exchange Model, is a community-driven, government-wide, standards-based approach to exchanging information.
The National Information Sharing Standards Knowledge Base and Help Desk provides an online knowledge base as well as live support.
NIEM may sound complex, but the premise of it is simple:
NIEM connects communities of people who share a common need to exchange information in order to advance their mission.
The Global Reference Architecture (formerly known as Justice Reference Architecture) is an information sharing architecture that will meet the needs of government at all levels, and fulfill the need for improved collaboration across communities.
There are approximately 100,000 justice agencies that have the critical need to share information across their various information systems, and this variety creates multiple layers of interoperability problems because hardware, software, networks and business rules for data exchange are different.
Many organizations are involved with the GJXDM. Along with the NCSC, here are a few of the major players:
Wayfarer is an exploration tool for the NIEM and the GJXDM. It provides advanced searching capabilities combined with detailed information about elements and types. Thanks to support from the Department of Justice, Wayfarer is freely available to the NIEM and GJXDM communities.
Stay tuned for the imminent release of NIEM SAW! “SAW” = Stand-Alone Wayfarer, a downloadable version of Wayfarer that empowers you to access the NIEM even when you lack an internet connection.
Information Exchange Package Documentation (IEPDs) define "reference" information exchanges, intended as models for information exchanges that meet specific business needs. NCSC has developed a comprehensive set of data standards for the exchange of judicial information. Categories of NCSC developed IEPDs include:
The Global Justice XML Data Model (GJXDM) is a comprehensive product that includes a data model, a data dictionary, and an XML schema that together is known as the Global JXDM. The Global JXDM is sponsored by DOJ's OJP, with development supported by the Global XML Structure Task Force (GXSTF).
