GJXDM
From Wikipedia, the free encyclopedia
The Global Justice XML Data Model (GJXDM or Global JXDM) is a data reference model for the exchange of information within the justice and public safety communities. The Global JXDM is a product of the Global Justice Information Sharing Initiative's (Global) Infrastructure and Standards Working Group (ISWG), and was developed by the Global ISWG's XML Structure Task Force (XSTF).
The Global JXDM is a comprehensive product that includes a data model, a data dictionary, and an XML schema that together is known as the Global JXDM. Global JXDM is independent of vendors, operating systems, storage media, and applications and is quickly becoming key technology for assisting how criminal and judicial organizations exchange information. The Global JXDM is sponsored by the United States Department of Justice (DOJ), Office of Justice Programs (OJP), with development supported by the Global XML Structure Task Force (GXSTF), which works closely with researchers at the Georgia Tech Research Institute (GTRI). New releases are issued by the GXSTF, which reviews and evaluates each version of the Global JXDM. The GXSTF solicits feedback from technical experts and practitioners in both industry and government and authorizes Global JXDM changes based on this feedback. All approved additions, deletions, and modifications are applied to future releases, with a cumulative change log published along with each release. When a reasonable number of updates are approved by the GXSTF, a new version is released.
The Global JXDM is an XML standard designed specifically for criminal justice information exchanges, providing law enforcement, public safety agencies, prosecutors, public defenders, and the judicial branch with a tool to effectively share data and information in a timely manner. The Global JXDM removes the burden from agencies to independently create exchange standards, and because of its extensibility, there is more flexibility to deal with unique agency requirements and changes. Through the use of a common vocabulary that is understood system-to-system, the Global JXDM enables access from multiple sources and reuse in multiple applications.

[edit] New Version 3.0.3 released
In September, 2005, the Office of Justice Programs (OJP), together with the Global Justice Information Sharing Initiative (Global), officially issued a newer version of the Global Justice Extensible Markup Language (XML) Data Model (Global JXDM) to the justice community, Version 3.0.3. ([1]) This "maintenance" release of the Version 3.0 Global JXDM series is enhanced to increase the ability of justice and public safety communities to share justice information at all levels laying the foundation for local, state, and national justice interoperability.
Some of the enhancements incorporated into Version 3.0.3 include the addition of new components that are compatible with previous version 3.0.2, new "sequenceID" values for "PersonNameType" sub-elements to assign an alternate ordering independent of the physical XML sequence, and an updated Frequently Asked Questions (FAQs) ([2]) resource that incorporates content from the Global JXDM Version 3.0 Reference Notes along with added FAQs.
An important feature is that the Global JXDM, Version 3.0.3, is forward compatible with all XML instances written for Global JXDM, Version 3.0. Global JXDM, Version 3.0, instances validate with all 3.0.3 schemas and schema subsets. Global JXDM, Versions 3.0.2 and 3.0, will remain available indefinitely. For a list of specific updates, refer to the Global JXDM Change Log ([3]).
Since its first prerelease in April 2003, the Global JXDM has continued to undergo intensive reviews, receive feedback and error reports online from the public, and provide a Global JXDM Listserv discussion forum for sharing expertise and support. Today, more than 50 law enforcement and justice-related projects have been implemented utilizing the Global JXDM, further demonstrating the flexibility and stability of the Global JXDM.
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 Versions 3.0.2 and 3.0. See the FAQ on compatibility ([4]) for an explanation.
