Abstract
This article describes the works related with the development of an information platform to render accessible the knowledge on casting technologies. The initial part presents the results of a survey on the preferences of potential users of the platform regarding areas of the used knowledge and functionalities provided by the system. The second part contains a presentation of selected modules of the knowledge with attention focussed on their functionalities targeted at the user needs. The guide facilitating the use of the platform is a “virtual handbook”. The System is used as a coupling link in the diagnosis of defects in castings, while ontological module serves the purpose of knowledge integration when different sources of knowledge are used.
