Integral to the success of the Global Justice XML standards effort is the promulgation of written guidelines to facilitate Global JXDM implementation by the justice community. The Bureau of Justice Assistance (BJA), Office of Justice Programs (OJP), U.S. Department of Justice (DOJ), awarded a grant to SEARCH, The National Consortium for Justice Information and Statistics, to provide Global JXDM technology assistance and to develop a User Guide to support Global JXDM implementation. A Global JXDM User Guide Review Committee, comprised of subject-matter and industry experts, was formed to develop this guide. As a result, Building Exchange Content Using the Global Justice XML Data Model: A User Guide for Practitioners and Developers is now available for users at all levels of technical proficiency and Global JXDM implementation readiness. While this User Guide is not a primer on XML or data processing, BJA, in developing the outline, realized that the guide needed to reach a broad audience. Through its experience in providing technical assistance over the past year, BJA discovered that agencies and jurisdictions are at varying levels of readiness with respect to implementing the Global JXDM. As a result, the guide was developed for those at the evaluation and exploration stage, as well as for those who have incorporated XML into their systems' architecture but still need instruction and examples defining information exchange packages, queries, and messages.
