NIEM 2.1

Description

NIEM is the National Information Exchange Model. This is an interagency initiative to provide the foundation and building blocks for national-level interoperable information sharing and data exchange. The NIEM project was initiated on 28 February 2005 as a joint venture between the U.S. Department of Homeland Security (DHS) and the U.S. Department of Justice (DOJ) with outreach to other Government departments and agencies. The NIEM leverages both the Global Justice XML Data Model (GJXDM) reference model and the GJXDM XML-based framework and support infrastructure.

This package contains the NIEM reference schemas (Core, code lists, domains, type adapters for external standards, as well as the schemas, schema profiles, or adaptations for those standards.) It also contains a cumulative change log and the spreadsheet. NIEM provides practitioners and developers with a baseline set of XML Schema components for building Information Exchange Package Documentation (IEPDs).

NIEM release 2.1 is based on the NIEM Naming and Design Rules (NDR) 1.3 and the Type Augmentation Supplement to NDR 1.3 (version 1.0, 24 September 2009).
