OneDOJ

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

External partners may access and search the OneDOJ system (but may not contribute information to the system) through a federated access service. As of October 2010, there were over 20 million searchable records and nearly 700 registered users, including both federal law enforcement agencies and local law enforcement agencies.
