What is the Global Justice Extensible Markup Language Data Model (GJXDM)?
The Global Justice Extensible Markup Language Data Model (GJXDM) is an XML standard designed to create a uniform method for law enforcement and judicial agencies to exchange criminal justice information in a timely manner.
GJXDM removes the burden from agencies to independently create exchange standards. Its extensibility allows for flexibility to deal with unique agency requirements and changes. GJXDM is an object-oriented data model for organizing the content of a data dictionary, the Global Justice XML Data Dictionary (GJXDD), in a database. From this database, an XML schema specification can be generated that consistently represents the semantics and structure of common data elements and types required for information exchange within the justice and public safety communities. There are three primary parts to the GJXDM: the Data Dictionary (identifying content and meaning), the Data Model (defining structure and organization), and the Component Reuse Repository (a database).
The work accomplished to date, based on participation by practitioners from the justice and public safety communities, has resulted in the creation of a data model that can be used to generate data schema which will facilitate information sharing among the various jurisdictions of those communities. This was done in a manner that reduced the cost of developing the technical solutions required, simplified the process and associated products, and enhanced the interoperability quotient of the end product. The approach combines successful practices in data modeling with recent technology standards for XML schema.
