Wikipedia
Diplopedia, billed as the Encyclopedia of the United States Department of State, is a wiki running on a State internal Intranet, called "OpenNet". It houses a unique collection of information pertaining to diplomacy, international relations, and Department of State tradecraft.
The wiki may be used by U.S. foreign affairs agencies domestic and abroad with State intranet access. It is also available to the United States intelligence community and other national-security related organizations using the Intelink-U network as a mirrored, read-only archive. Both sites are rated by the government as sensitive but unclassified. The wiki on either network is not open to the public.
Diplopedia is a project of the Office of eDiplomacy (eDip), located in the Bureau of Information Resource Management within the Department of State. Diplopedia uses MediaWiki, the same software used by the Wikipedia free-content encyclopedia project.
