The document summarizes the Concept Glossary Manager (CGM) which was developed as part of the Intelligent Content Management System (ICONS) project. CGM allows storing and processing concepts and concept relations using a topic maps approach. It consists of a topic maps engine, navigator, server, and editor. The topic maps engine supports import/export of topic maps and has advanced features like distributed computing and user rights management. The topic maps scripting language (TMSL) allows modifying topic maps programmatically. The navigator uses an ontology to generate specialized interfaces for visualizing and modifying topic maps in an intuitive way.
