Introduction
The Global Justice XML Data Model (Global JXDM) is intended to be a data reference model for the exchange of information within the justice and public safety communities. The Global JXDM is sponsored by the U.S. Department of Justice (DoJ) Office of Justice Programs (OJP), with development supported by the Global Justice Information Sharing Initiative's (Global) XML Structure Task Force (GXSTF).

Current Release
| 3.0.3 | The Global JXDM, Version 3.0.3. Global Justice XML Data Dictionary (Global JXDD) types and properties are rendered as XML Schema types, elements, and attributes. Also included are the most current enumeration type schemas (code tables) and their proxy schemas. Version 3.0.3 is compatible with 3.0.2 and 3.0. Refer to the FAQ on compatibility for an explanation. |
| Patch1 | There are semantic errors in the documentation elements (only) within the Uniform Crime Reporting (UCR) code schema (ucr.xsd). These errors have no effect on validation, but users who rely on the documentation within this schema to determine the meaning of each code value could place incorrect codes within their XML instances. Patch1 fixes these errors in GJXDM Release versions 3.0, 3.0.2, and 3.0.3 without forcing the user to move to a new version. This patch is also included in the .zip archive files for each release. |

Disclaimer
The Global Justice XML Data Model (Global JXDM) and Data Dictionary (Global JXDD) are available for commercial use. The authoritative source for the Global JXDM is http://www.it.ojp.gov. This document does not require prior permission for use. Updated Global JXDM releases will be published periodically. All operational releases will remain online indefinitely. Every effort will be made to maintain forward compatibility; however, backward compatibility may not be supported.
Earlier prereleases (all 3.0.0.n versions and earlier) are no longer updated, but will remain available for an unspecified period of time. Prereleases were essentially alpha versions of the Global JXDM. Implementers that use prerelease specifications do so at their own risk.
