AV-Petri Systems: How to Get Together Abstraction and Views for Petri Systems?

In order to model complex systems it is indispensable to structure the modelings. The mechanism of abstraction as well as the usage of views is very helpful for structuring. In this paper I will discuss these aspects in the context of Petri systems in order to get fundamental definitions. It turns out, that with respect to many different definitions of Petri systems only a "generic definition" is possible. To get final definitions for concrete types of Petri systems it requires much further work. [ABSTRACT FROM AUTHOR]
