All communications projects funded by the Department of Homeland Security must adhere to the Global Justice XML Data Model (GJXDM), a technology that allows law enforcement and criminal justice systems to share information, even when those systems represent the information in different ways. This requirement includes new computer-aided dispatch (CAD) and records management systems (RMS).

Through the use of GJXDM, law enforcement officials can share information without having to spend time and resources on re-designing their existing systems. GJXDM offers many benefits, including cost and time savings and a clear definition of the boundaries of data ownership.

In southern California, a local consortium consisting of the Los Angeles County Sheriff's Department, the Los Angeles Port Police, the San Diego Harbor Police Department, and the Unified Port of San Diego is using GJXDM as a tool to help predict potential activities by terrorists and criminals.

The group, known as the Regional Information Sharing and Analysis (RISA) consortium, is using GJXDM to share call-for-service data and field interview data, which is examined to predict the potential terrorist or criminal activities.

The GJXDM still has data security issues that need to be ironed out, but until these issues are resolved agencies can rely on common memorandums of understanding that address the issue of data protection.
