The Open Source Information System (OSIS) was formerly the name of an unclassified network serving the intelligence community with open source intelligence.
In mid 2006, the name OSIS and the network and content to which it referred were decoupled. The network piece is now named DNI-U while the content piece is named Intelink-U.
The DNI-U network is maintained by the DNI-CIO Intelligence Community Enterprise Services office (ICES).
