The IHMC CmapLite program is a version of CmapTools that has been reduced in functionality to allow it to run on smaller machines with a reduced memory size, in particular the Intel Classmate and the OLPC XO running Windows XP. IHMC CmapLite is also appropriate for older machines with small main memory. As is CmapTools, CmapLite is available in Windows, Mac OS X, Linux, and Solaris versions. The IHMC CmapLite 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 servers (CmapServers) anywhere on the Internet, link their Cmaps to other Cmaps on servers, automatically create web pages of their concept maps on servers, and edit their maps synchronously (at the same time) with other users on the Internet.
