This manual provides information about installing and using ConceptBase. For new users of ConceptBase we recommend to follow the installation guide for getting the system started and then to work through the ConceptBase Tutorial. More information about the knowledge representation mechanisms, the applications, and the implementation concepts can be found in the references. Chapter 2 describes the ConceptBase version of the Telos language and gives some examples for its usage. Section 3 describes the X11 ConceptBase Usage Enviroment and explains shortly the new ConceptBase Java User Interface.
Appendices contain a formal definition of the Telos syntax and internal data structures (A). Appendix B summarizes ConceptBase mechanism for assigning graphical types to objects and adapting the graphical browsing tool for specific application needs. Appendix C contains the full Telos notation of an example model (C.1) and a case study on the modeling of entity-relationship diagrams with Telos (C.2).
