Welcome to the NIEM Community!
The value of information-sharing and exchange efforts can best be achieved through the active participation and collaboration of the many organizations involved in protecting and serving our nation. We invite you to learn more and become part of the NIEM community.
As a community member of NIEM, your involvement could span one or more You also don’t need to be aligned to a formal NIEM domain to use NIEM, as NIEM’s core elements are universal and applicable to many or all.
NIEM domains are communities of interest, or , that are formally established, with an executive steward, to officially manage and govern a portion of the NIEM data model.
A COI is a group of people who share a common concern, set of problems, or interest in a topic. Within the context of NIEM, COIs come together based on a common need to exchange information in order to advance their missions.
COIs can be composed of multiple domains or can be a sub-set of a single domain. For example, a multi-faceted issue, such as human trafficking, involves both law enforcement organizations to handle investigations, and immigration and social service organizations to provide victim assistance. Therefore, the anti-human trafficking community includes stakeholders from the Justice, Human Services, and Immigration domains. Conversely, a broadly scoped domain such as the Maritime domain could contain multiple COIs such as Coastal Defense, Marine Protection, and Fisheries.

NIEM has data model content for eleven community-specific business areas--NIEM domains. In addition, several emerging communities are working towards developing data model content, which may lead to the establishment of new domains. On the pages linked below, you can learn about each domain as well as collaborate with its members.

The NIEM Biometrics domain defines the representation for biometrics data such as facial images, fingerprints, iris scans, and DNA so that providers and consumers of biometrics information can exchange this data. Biometrics information is used extensively in different areas of government including homeland security, law enforcement, and defense, just to name a few.
The CBRN domain currently supports efforts to detect and interdict radiological and nuclear threats.
The Children, Youth, and Family Services domain supports timely, complete, accurate, and efficient information-sharing among the partners that can help improve outcomes for children and youth whose circumstances make them particularly vulnerable.
The NIEM Emergency Management domain supports community efforts to coordinate and integrate all activities necessary to build, sustain, and improve the capability to mitigate against, prepare for, respond to, and recover from threatened or actual natural disasters, acts of terrorism, or other man-made disasters.
The NIEM Immigration domain supports immigration-related services and benefits, such as naturalization and work authorization. In addition, this domain supports information sharing and exchange to improve those services and law enforcement activities as well as foster better collaboration with external partners.
The Infrastructure Protection domain supports the collaboration of federal, state, tribal, local, and private-sector partners to strengthen not only the protection of critical infrastructure, but also its resilience.
NIEM's Intelligence domain is the standard of choice for exchanging intelligence among any federal, state, and local agencies on a foreign or domestic basis. Domain members identify the operational needs to exchange intelligence, as well as the opportunities to share information with other domains and functions in justice and homeland security. Domain members represent the full range of operations that deal with the gathering, analysis, fusion, and dissemination of intelligence, as well as the ability to act upon it.
This NIEM domain supports the mission of protecting the movement of international trade across borders by facilitating real-time exchange of information with state, local, international, and other partners.
The Global Justice XML Data Model (Global JXDM), created in March 2001, evolved from a reconciliation of data definitions into an XML-based framework that would enable the entire justice and public safety communities to effectively share information at all levels. In 2005, GJXDM 3.0.3 became the first domain in NIEM. The Justice domain continues to provide the criminal justice system with the data elements, objects, and properties it needs to share critical information between jurisdictions and levels of government.
The Maritime domain supports the effective understanding of anything associated with the global maritime domain that could impact the United States' security, safety, economy, or environment. NIEM facilitates this understanding through effective, timely sharing of vital, secure information among many key partners.
The Screening domain supports, coordinates, and harmonizes the information needs of a number of homeland security mission areas that rely on accurate, timely information in support of a wide range of screening and credentialing activities.
