This paper presents a method, how to create an interactive fault databasis for ceramics in the web, called CeraNet. This universal method can be adapted to other products easily. The fault database contains not only descriptions of faults and countermeasures, but also detailed information on production plants and machinery, references to relevant literature, description of raw materials etc. The data is stored in graphs, i.e. highly connected information networks. When generating a web site this approach guarantees, that all hyperlinks exist, i.e. „dead links“ are impossible. Navigation is easily done by following hyperlinks.
