Intellipedia is an online system for collaborative data sharing used by the United States intelligence community (IC). It was established as a pilot project in late 2005 and formally announced in April 2006 and consists of three wikis running on JWICS, SIPRNet, and Intelink-U. The highest level of classification allowed for information on the three wikis are Top Secret, Secret, and Sensitive But Unclassified/FOUO information, respectively. They are used by individuals with appropriate clearances from the 16 agencies of the IC and other national-security related organizations, including Combatant Commands and other federal departments. The wikis are not open to the public. Intellipedia is a project of the Office of the Director of National Intelligence (ODNI) Intelligence Community Enterprise Services (ICES) office headquartered in Fort Meade, Maryland. It includes information on the regions, people, and issues of interest to the communities using its host networks. Intellipedia uses MediaWiki, the same software used by the Wikipedia free-content encyclopedia project.
