information sharing is a national imperative
Information sharing is a national imperative

In detecting, preventing, responding to and investigating crimes, disasters and terrorist acts, the exchange of information among multiple engaged agencies must be timely and accurate and therefore highly automated.

Most existing computer systems are not designed to facilitate information sharing across disciplines and jurisdictions.

Automated information sharing between agencies requires the definition of common standards for linking disparate systems among federal, state, local and tribal agencies.

niem the national program
NIEM – The National Program
  • Addressing the national information sharing imperative embraced by the Departments of Justice and Homeland Security, and the Office of the Director of National Intelligence
  • Advancing the development of information exchanges critical to assuring the safety and security of our citizens, property and infrastructure
  • Providing the “standard of choice” for federal, state, tribal, and local governments.
niem the national model
NIEM – The National Model
  • A National Standard that enables the sharing of information of critical relevance to Community of Interest partnerships
  • A Common Vocabulary providing agreed-upon terms, definitions, and formats - independent of the way information is stored in individual agency systems
  • A Structured Approach to developing the reference documentation that expresses NIEM information exchange requirements in an implementation ready format – the Information Exchange Package Documentation (IEPD) development process
participating communities and governance
Participating Communities and Governance

Defining Data Components

Defining data components unique to a domain will be done by subject matter experts who are representatives of the domain following basic rules for definitions and terms

A group representing all participating domains will define those data components that are universal or commonly used by more than one domain again using the same basic rules

business driven information exchanges
An Information Exchange Package (IEP) begins with a business need for a particular exchange.

IEP Documentation (IEPD) describes how that exchange should be expressed using the NIEM.

The IEPD is a key point for introducing new elements to NIEM and for reusing existing ones.

An IEPD itself can also be reused in whole or in part to speed development and lower the cost of sharing information.

Business Driven Information Exchanges
proof of concept and success
Proof of Concept and Success
  • AMBER Alert, built on GJXDM, is a proven success and has helped rescue more than 230 children nationwide.
  • Nlets - State owned system connecting all 50 states, territories along with every federal agency with a justice component.
      • Every agency, province many access pts.
      • Currently accepting nearly 90 million transactions per month
      • Rap sheets are one of the highest volume XML transactions
  • Any police officer in Ohio can search 600 separate police computer systems with a single GJXDM based query and response
  • In Maricopa County, AZ, a web service sends GJXDM compliant arrest information from the police to the prosecutor thus eliminating redundant data entry
  • In central Florida, 700 offenders were jailed over 12 months due to GJXDM-enabled sharing of data among 150 agencies; these offenders would not have been arrested without this information sharing
cost savings
Cost Savings
  • Using GJXDM the Pennsylvania State Justice Network (JNET) has reduced the message development process from an average of 9 months to approximately 6 weeks.
    • More importantly, Pennsylvania has implemented a standardized, repeatable process, for all integrated technology solutions, and potential taxpayer savings have been identified in the millions of dollars.
  • Using GJXDM, the Missouri Office of State Courts Administrator (OSCA) reports having reduced development time by 50 percent, potential savings of $1.6 million over two years.
    • Previously, converting each court's system took 18-24 months, while they are now taking 6-9 months
  • Minnesota's Department of Public Safety anticipates saving over $10 million over a three-year period by using the XML Data Model rather than developing its own statewide standard for information systems.
niem adoption and use updates
NIEM Adoption and Use Updates
  • Suspicious Activity Report IEPD under development
  • Several Fusion Center RFP’s have been released requiring NIEM conformance
  • DOJ and DHS grant language
  • DHS to develop NIEM IEPDs for hospital availability in response to an incident (due in April)
  • DOJ programs, such as LCMS, NDEx and Sentinel, through their system design efforts are ensuring their exchanges will be NIEM-conformant.
  • Several states have adopted NIEM for developing statewide justice information systems using a NIEM/GJXDM based state data model
  • New York State Division of Criminal Justice Services is developing over 200 NIEM IEPDs and have developed NIEM IEPDs which are available at
  • Vendor Community Interest
the niem value proposition
The NIEM Value Proposition
  • Agencies and organizations that adopt NIEM will be able to:
    • Gain faster access to critical information
    • Create automated information exchanges with partners
    • Leverage existing systems and avoid high costs of system replacement
    • Engage additional information exchange partners in the future.
    • Save time and funding by reusing already developed IEPDs
    • Participate in ISE Implementation Plan
    • Contribute to shaping national standards for information sharing
