The goal of the TMNav project is to provide an intuitive graphical interface for topicmap navigation and editing. TMNav relies on TM4J, an open source topicmap toolkit, that is written in Java.

TMNav bases on a library, called Panckoucke, which is used in several applications as a generic toolkit for topicmap navigation and editing. As TMNav, Panckoucke is also developed as a subproject of TM4J.
