OneDOJ operates with two primary objectives:

• to serve as DOJ’s system to share criminal law enforcement information internally across investigative components
• to provide regional criminal law enforcement connectivity for authorized users to conduct federated searches of OneDOJ information. This connectivity will also provide authorized DOJ users the means to query partner law enforcement information as governed by the respective Memorandum of Understanding (MOU).

OneDOJ is a DOJ repository for law enforcement information shared with other federal, state, local and tribal law enforcement agencies through connections with regional information sharing systems. All DOJ law enforcement components – ATF, BOP, DEA, FBI, and USMS - are sharing information under consistent policy and technical standards. Information shared includes open and closed case documents, investigative reports, witness interviews, criminal event data, criminal history and incarceration information, and identifying information about individual offenders.

Information sharing through OneDOJ with law enforcement outside of DOJ is achieved by interconnecting with regional systems to access DOJ information relevant to their users. Currently, the LInX-NW and ARJIS systems are connected with OneDOJ. This allows, for instance, LInX users in Washington State to access shared DEA case files from the Seattle field office from the LInX user interface. Additionally, the bi-directional nature of the connection allows DOJ users to access state and local information in the regional systems from the OneDOJ user interface.

Interconnection with OneDOJ is accomplished through an open, XML-based, NIEM-compliant standard developed by the DOJ Law Enforcement Information Sharing Program (LEISP) and its partners. The standard, called LEXS-SR (LEISP Exchange Specification – Search and Retrieval), defines the interface between OneDOJ and regional sharing systems.
