The Global Justice Information Sharing Initiative (US Department of Justice, Office of Justice Programs) has provided new information on the Justice XML Data Model, including a prerelease of the Justice XML Data Dictionary version 3.0. The Justice XML Data Dictionary (JXDD) prerelease version 3 "is intended to solicit review and feedback from the justice and public safety communities. JXDD v3 has been reviewed by the Global Justice Information Sharing Initiative (Global) Infrastructure/Standards Working Group (GISWG). The XSTF development team built upon existing local, state, and federal documented data requirements, gathering source documents including XML schemas, database schemas, data dictionaries, code tables, and other documented data requirements. From these source documents approximately 16,000 data elements, types, and attributes were identified. These were analyzed and reduced to 2,000 unique data elements that were then incorporated in around 300 data objects or reusable components. The GISWG committee's XML Structure Task Force (XSTF) that developed the JXDD v3 would now like to open review to a wider audience of government and industry persons, with technical and practical expertise in the justice and public safety domain, until mid-June 2003. The XSTF will review all feedback and decide which modifications to incorporate into future prereleases." The JXDD XML Schemas depend upon twenty-some external schemas, code lists, specifications, and publications created by other groups and organizations. The JXDD release provides annotated versions of these XML Schemas. JXDD v3 is available for commercial use and does not require prior permission for its use; however, the JXDD prerelease is subject to change.

JXDD Bibliographic Information

The version 3.0 prerelease of the Justice XML Data Dictionary (JXDD) contains an XML schema implementation of the JXDD, as well as an Adobe Acrobat specification of the types and properties of the JXDD. The PDF document also includes links to the code tables upon which the data dictionary relies.

Justice XML Data Model Background

The Justice Extensible Markup Language (XML) Data Model effort was organized to explore and facilitate information sharing and technology integration in the justice and public safety communities.

Preliminary efforts began in 2001 when data exchange experts from the Joint Task Force Rap Sheet Standardization Project, LegalXML Court Filing Standard Initiative, and the Regional Information Sharing Systems, XML Data Exchange Specification, participated in meetings facilitated by the Global Justice Information Sharing Initiative (Global) Infrastructure/Standards Working Group (GISWG). In December 2001, the American Association of Motor Vehicle Administrators joined the effort.

In August of 2002, the XML Structure Task Force (XSTF), under GISWG, was established for the purpose of identifying data requirements, best practices, and expanding the content and applicability to the broader justice and public safety communities. Local and regional expertise was added by representatives from such groups as CriMNet and the Los Angeles County Consolidated Criminal History Reporting System. Working with researchers from the Georgia Tech Research Institute (GTRI), the XSTF developed a technical framework and methodology that allows for collection and analysis of massive data requirements, supports flexibility and extensibility, and provides a migration path to future technologies. Additionally, throughout the process, staff support was provided by standards specialists from the Institute for Telecommunication Sciences, National Telecommunications and Information Administration, sponsored by the National Institute of Justice, Office of Justice Programs.

Key to the success and speed of this effort was the decision to build on existing local, state, and federal documented data requirements. The XSTF gathered numerous existing source documents including XML schemas, database schemas, data dictionaries, code tables, and other documented data requirements. From these source documents approximately 16,000 data elements, types, and attributes were identified. These were analyzed and reduced to 2,000 unique data elements that were then incorporated in around 300 data objects or reusable components. These data objects have inherent qualities enabling them to be accessed from multiple sources through this effort, and reused in multiple applications. The result of this work is the standardization of core components to allow for increased interoperability among and between justice and public safety information systems.
