An object oriented system implementing KNOs

Abstract

We discuss a distributed object-oriented system written in LISP that implements KNOs (KNowledge acquisition, dissemination and manipulation Objects). The system emphasizes advanced features like object autonomy, mobility and dynamic inheritance. The objects are active, independent entities that can travel in a local area network and protect themselves from external aggressions. A dynamic inheritance mechanism enables them to modify their behaviour during their lifetime. We give a description of our system, illustrate its functionality with selected examples, and discuss its advantages for software development and Office Information Systems.
