Texas Data Exchange

Texas Data Exchange (TDEx)
The Department of Public Safety (TXDPS) manages TDEx which shares the same mission and core goal as the FBI’s National Data Exchange (N-DEx) to fill the information sharing gap regarding law enforcement incident and other data.  After the attacks of September 11, 2001, one of the universally recognized deficiencies of law enforcement information sharing was in this area.  While numerous local and regional information sharing systems have been developed that are proving exceedingly successful, it was not until N-DEx was created that a nationally scaled system emerged.  In Texas, TDEx has taken on this role at the state level, and is the mechanism by which Texas agencies contribute law enforcement and criminal justice data to N-DEx.  TDEx has been collaborating with FBI N-DEx and contributes TDEx incident data daily utilizing the NIEM compliant N-DEx IEPDs.

National Data Exchange (N-DEx)
One of the stated goals of N-DEx is to create the capability for local agencies to create “virtual regional information sharing systems” within the large N-DEx database.  That is, jurisdictions in major metropolitan areas, in locations where multiple states’ borders intersect, or along major highways, can all get the benefit of each other’s incident data for investigative purposes, if they just all participate in N-DEx.  On a large scale, the participation of agencies along interstate highways across multiple states can accrue this benefit as they all are able to contribute data to and make inquiries into N-DEx.  To take advantage of this concept for Texas, and to build the Texas piece of this infrastructure in N-DEx for the major highway corridors to other states, (I 10; I 35; I 20, US59, and others) TXDPS has placed an emphasis on this strategy.  The map below is indicative of our success with TDEx along several major highways but demonstrates the lack of local agencies located in the southern border region including the I-20 and I-10 flowing from the Texas-Mexico border.  The goal of information sharing initiatives is to continue efforts and extend it to other highways.  By increasing that coverage, we are making the most possible information available for the agencies in Texas, and by virtue of the pending connection with N-DEx, making that information immediately available nationwide to N-DEx users who may be affected by criminal traffic along these highways.

Remotely Hosted Criminal Incident Based Records Management System (RRMS) Project
Many local Texas Law Enforcement Agencies (LEA) do not have critical financial or technical resources necessary to establish and maintain a records management system to store incident and related data generated within its jurisdiction.

The TXDPS RRMS Project is intended to provide a remotely hosted records management system (RMS), jail management system (JMS) and/or computer aided dispatch (CAD) local LEAs can access as services (coupled or stand alone) provided by the successful vendor(s).  The RRMS will provide the local LEAs with a virtual database that they will be able to remotely access on a 24x7 basis in a manner that is consistent with the security requirements articulated in the Federal Bureau of Investigation (FBI) Criminal Justice Information Services (CJIS) Security Policy.

The goal of the RRMS Project is to provide local law enforcement agencies in critical Texas jurisdictions with automated information sharing capabilities.  The goal of this project directly addresses the Department of Justice’s (DOJ’s) Global Justice Information Sharing Initiative to overcome obstacles in sharing justice information necessary to solve crimes, community protection and resource management through increasing the quantity of local jurisdictions capable of cross-boundary information sharing.  The strategy of this project will build upon existing sharing methodologies employed by TDEx as well as the FBI’s N-DEx to add the additional law enforcement agencies to the number of agencies already reporting law enforcement incident data.  These efforts will be coordinated between TXDPS and local Texas law enforcement agencies to add local agency RMS, JMS and/or CAD data sources to TDEx through proven data extraction, standardization and submission processes currently employed which facilitates subsequent data promotion to N-DEx utilizing the NIEM compliant N-DEx.

National Information Exchange Model (NIEM)
NIEM is a partnership of the U.S. Department of Justice and the Department of Homeland Security. It is designed to develop, disseminate and support enterprise-wide information exchange standards and processes that can enable jurisdictions to effectively share critical information in emergency situations, as well as support the day-to-day operations of agencies throughout the nation.

NIEM enables information sharing, focusing on information exchanged among organizations as part of their current or intended business practices. The NIEM exchange development methodology results in a common semantic understanding among participating organizations and data formatted in a semantically consistent manner. NIEM will standardize content (actual data exchange standards), provide tools, and managed processes.

NIEM builds on the demonstrated success of the Global Justice XML Data Model. Stakeholders from relevant communities work together to define critical exchanges, leveraging the successful work of the GJXDM, and further enhancing the capabilities of the NIEM model by developing Information Exchange Package Documentation (IEPD).

You can search the latest IEPDs through the NIEM IEPD Clearinghouse, also accessible from the Implementation Assistance section.

For more information about NIEM and the associated training, standards, and events, see the NIEM-related pages outlined at the left or visit the NIEM website directly at www.niem.gov.

This project coincided with and supported the implementation of the recommendations set forth in the “Texas Path to NIEM”, which is a statewide strategy for information sharing using NIEM standards published by the Texas Integrated Justice Information System (TIJIS).  The primary objectives of this initiative were:

TIJIS membership includes the following state agencies, associations, and local agencies:
