The KEEP toolkit which has been around for a while is a set of web-based tools that help teachers, students and institutions quickly create compact and engaging
knowledge representations on the Web.
The KEEP Toolkit is a project of the Knowledge Media Lab at the Carnegie Foundation for the Advancement of Teaching.
It can now be fully integrated with Sakai, an online open source Collaboration and Learning Environment, used by a wide range of institutions to support teaching and learning, portfolios and research collaboration. A plug-in for Sakai 2.1 or later enables one-stop authentication for easy access of KEEP Toolkit from within a Sakai instance through the use of web services. (The plug-in package is available for the distributable version of KEEP 1.9).
