NIEM 1.0

Description of NIEM 1.0

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).

NIEM Core Schemas

• common: NIEM common core
• universal: NIEM universal core

NIEM Domain Schemas

• emergencyManagement: NIEM emergency management domain schema framework

• geospatial: Defines NIEM adapter types for external geospatial components defined by OGC, LIF, LandXML, IAI, and ANSI. This schema defines NIEM adapter types for external geospatial components defined by OGC, LIF, LandXML, IAI, and ANSI. It also defines property types and elements according to the conventions required by the Geography Markup Language (GML) specification. These property types and elements allow niem geospatial adapter elements to be referenced from GML conformant application schemas. This situation is described in external-standards.pdf as Case 2: External schemas reference, import, and use NIEM components., but not addressed by that document. However, it applies to the development of the GML application schemas that must in most cases be developed to effectively use GML in niem IEPs. Note for schema readers: The XML/Schema specification does not require processing implementations to transitively import definitions from imported schemas. To assure that all required definitions are available, a schema must re-import the schemas that are imported by the schemas it imports. Such re-imports are noted in the documentation.
