Abstract: The article discusses the notion of state spaces of object-oriented Petri nets (OOPNs) associated to the tool called PNtalk and the role of identifiers of dynamically appearing and disappearing instances within these state spaces. Methods of working with identifiers based on sophisticated naming rules and mechanisms for abstracting names are described and compared. Some optimizations of state space generating algorithms for the context of OOPNs are mentioned, as well. Finally, some possibilities of specifying properties of systems to be checked over the state spaces of their OOPN-based models are discussed.
