Why use GJXDM?
Proactive information sharing promotes public safety by allowing users to make accurate and rapid decisions. GJXDM lets users share critical information better and faster, and reduce costs and overcome delays in case management. GJXDM provides for electronic data sharing in a simple automatic process between previously incompatible systems.
The automation revolution led to piecemeal interoperability, individual software applications that were programmed to only serve a single agency or a group of agencies. This approach did not take into account the need to share information between agencies with different applications. Yet the need to share information is now important as ever.
Exchange of information can be accomplished between different applications by using a uniform standard, regardless of computer system or platform. Luckily, this is exactly what XML allows. Global Justice XML Data Model is an XML markup-language that serves this purpose for law enforcement and related agencies. GJXDM has a standard Justice specific vocabulary and agreed to objects that all agencies can use to describe information. Below is a scenario which illustrates how the useof GJXDM yields the best possible result for lawenforcement.
A local police officer conducts a routine traffic stop for speeding. When the police officer approaches the car, he discovers that there is a young female passenger alongside the male driver. Thereafter, the police officer enters the driver's information into his mobile data computer. Immediately the system queries all participating neighboring jurisdictions and agencies, besides his local district, for any information concerning the driver. Information is returned from a state Sex Offender Registry that the driver is a registered sex offender who is prohibited from being the company of any child under the age of 16. Further, the officer also receives information from the Department of Corrections that there is a warrant for the driver's arrest because he is wanted for not registering with them. It turns out that the passenger is actually a 12 year old girl, so the driver is arrested based on both pieces of information obtained using GJXDM. Without GJXDM, the driver might have just received a speeding ticket. Luckily the XML technology, GJXDM, allowed for the quick and easy transfer of information between the local police officer's computer and the systems of all the other appropriate agencies.
The scenario provided is only one of many examples of how the exchange of information is crucial in ensuring justice. The XML enhanced data sharing provides for a common framework to improve data and information sharing. And as XML is increasingly being adapted as the IT standard globally, more tools will become available to work with XML. Also, XML is a very adaptable language, since it works on top of most existingservers (nothing needs to be replaced to work withXML).
