NIEM/GJXDM Training

Course Description: NIEM (National Information Exchange Model) and GJXDM (Global Justice XML Data Model) is are XML metadata registry created by the US Department of Justice for the exchange of data between Criminal Justice agencies across the US.  These systems are complex yet powerful system.  GJXDM includes almost 2,700 data elements and comes with some of the most advanced sub-schema generation tools available for creating semantically precise exchange documents.  This class covers an background, of GJXDM, description of the structure of the GJXDM, as well as hands-on experience using the GJXDM subschema generation tools.

Target Audience: This class is appropriate for data architects, project managers, business analysts,  and software developers exchanging criminal justice documents.  This base section of this class uses visual representations of XML Schema provided by tools such as Altova's XML Spy.  This allows people without knowledge of XML Schema file structure to understand the structure of GJXDM.  Advanced labs will require a background of reading and modifying XML Schemas.

Prerequisites: Knowledge of how to use a Microsoft Windows computer including mouse and keyboard skills are essential for the successful completion of the labs.  Knowledge of computer systems operation, databases and data structures and data types is also helpful.  If the class participants have a background in XML (see XML course above) this class proceed through the introductory material much faster. Knowledge of XML Schema is required for many of the optional advanced labs.
