NATIONAL INFORMATION EXCHANGE MODEL

Mission

The IT domain ensures and enables relevant government agencies to exchange and share information, resulting in:

  • Greater facilitation of trade
  • More effective identification and elimination of security threats before they arrive at ports and borders.

The IT domain model aligns with the World Customs Organization (WCO) Data Model and also supports the Customs Business Process models. The domain supports the international trade mission area by facilitating real-time information exchange for many federal, state, local, and international entities, as well as other partners.


Governance

The IT domain is stewarded by the U.S. Department of Homeland Security (DHS)’s Customs and Border Protection (CBP). Government agencies that are interested in the trade data for various enforcement, security, and financial purposes participate in the domain.

International Trade Word Cloud
This word cloud shows the most commonly used International Trade domain elements in the NIEM data model

The IT domain model has 135 types (2,219 code values in 22 enumerated types and 113 other types) and 540 property elements. The IT domain has been harmonized with the CBRN, Immigration, Maritime, and Screening domains to eliminate redundancies of types and to enforce standardization in the representation of types across these domains. IT domain data elements have been and will continue to be harmonized with other domains in upcoming versions of the NIEM model.

The IT domain in action

CBP implemented an interoperable web service for the International Trade dataset processed through the CBP Automated Commercial Environment (ACE) system. The ACE system uses a NIEM-conformant Information Exchange Package Documentation (IEPD) based mostly on trade data defined in the IT domain data model. The interoperable web service is used to share the trade data with 40 Partnering Government Agencies (PGA) for various enforcement purposes.
