The elements of an open KBS infrastructure

This paper describes the elements of an open knowledge based system infrastructure. These are: standard knowledge representation systems; a knowledge interchange format; a knowledge manipulation and query language; common shared ontology and an agent based software engineering model. These elements provide the means to achieve Knowledge Sharing and Reuse between heterogeneous knowledge based systems. The elements have been adopted as the basis of the conceptual design for the Advanced Technology Operations System ATOS being designed by the European Space Agency ESA.
