The IHMC CmapTools (http://cmap.ihmc.us/) program empowers users to construct, navigate, share and criticize knowledge models represented as concept maps. It allows users to, among many other features, construct their Cmaps in their personal computer, share them on places or servers (IHMC CmapServers) anywhere on the Internet, link their Cmaps to other Cmaps on servers, automatically create web pages of their concept maps on servers, edit their maps synchronously (at the same time) with other users on the Internet, and search the web for information relevant to a concept map.
A list of CmapServers can be found at http://dop2.ihmc.us/
The IHMC CmapTools client is free for use by anybody, whether its use is commercial or non-commercial. In particular, schools and universities are encouraged to download it and install it in as many computers as desired, and students and teachers may make copies of it and install it at home.
IHMC CmapTools has been translated into seventeen (17) different languages. It runs in Catalan, Chinese, Czech, Dutch, English, Basque, Finnish, French, Galician, German, Italian, Japanese, Kuna, Portuguese, Spanish, Swedish, and Turkish. IHMC Cmaptools defaults to the language of the operating system, but can be changed in the Preferences menu item.
