Abstract
Petri nets have been considered among the variety of formalisms and theories taken into account for giving a sound semantic basis to (concurrent) object-oriented systems and languages. Pursuing this research direction, we have defined a formalism called CLOWN (CLass Orientation With Nets) and discussed on it many object-oriented concepts, with special regards to a net-based notion of inheritance. We present the insights about the principles and the open problems of object-orientation that we derived by modelling in CLOWN a number of small to medium case studies. The current results suggest, as promising future efforts, the tighter integration with object-oriented analysis and design methodologies, especially aimed at the Smalltalk language
