Abstract. Category Theory is introduced as the mathematical model for object-oriented systems which are distributed, heterogeneous, real-time, embedded, and open-ended. Each object...
Abstract. One of the most novel features of Casl, the Common Algebraic Specification Language, is the provision of so-called architectural specifications for describing the modular...
This paper studies several applications of the notion of a presentation of a functor by operations and equations. We show that the technically straightforward generalisation of th...
Object Petri nets (OPNs) provide a natural and modular method for modelling many real-world systems. We give a structure-preserving translation of OPNs to Prolog by encoding the O...
Abstract. Compatibility of behavior, i.e. the correct ordering of messages, is one of the core aspects for the interaction between services as parts of an inter-organizational busi...
