For the new user, this guide provides a background and overview of the development of GJXDM, a general enterprise architectural overview, and a baseline set of technical concepts. For the more experienced or technical user, the guide moves from the technical framework to take the user further into a methodology for defining the business requirements of the information exchange, as well as an information exchange package development process guideline. Although many justice participants may not be technical, every user should benefit from several domain-specific "use cases," which are presented in the guide to illustrate how the process presented in the guide has resulted in successful information exchange development. Nontechnical users will also benefit from starting down the path of discovering the GJXDM standard. Policymakers should consider incorporating this information in their information technology planning and funding instruments. The guide also discusses compliance with new special-conditions language that affects grantees of the U.S Justice Department and the U.S. Department of Homeland Security. In addition, the guide presents information about GJXDM tools, resources, partners, terminology, and documentation. Appended supplementary data
