Abstract
In recent years many authors have come up with definitions of object Petri nets. They can be divided into two main classes: those that try to model object-orientation within a framework of Petri nets, and those modelling the token objects of an environment net by Petri nets but do not follow the paradigm of object-orientation. We compare some aspects of the latter kind with the foundations of Linear Logic and Linear Logic Petri nets, establishing some simulations between the formalisms.
