NIEM stands for the National Information Exchange Model. NIEM is an interagency initiative to provide the foundation and building blocks for national-level interoperable information sharing and data exchange. The NIEM project was announced and initiated on 28 February 2005. It is a joint venture between the U.S. Department of Homeland Security (DHS) and the U.S. Department of Justice (DOJ) with outreach to other departments and agencies. The NIEM leverages both the extensive Global Justice XML Data Model (GJXDM) reference model and the comprehensive GJXDM XML-based framework and support infrastructure.
This package is the NIEM 1.0. It contains the NIEM schemas (Core, code lists, domains, wrappers for external standards, as well as the schemas for those standards, or profiles of, or adaptations of.) It also contains a cumulative change log and the spreadsheet. This version of NIEM is intended to provide users, practitioners, and developers with a baseline set of XML Schema components for building Information Exchange Package Documentation (IEPDs).
