Objects are studied as higher-level net tokens having an individual dynamical behaviour. In the context of Petri net research it i s quite natural to also model such tokens by Petri nets. To distinguish them from the system net, they are called object nets. Object nets behave like tokens, i.e., they are lying in places and are moved by transitions. In contrast to ordinary tokens, however, they may change their state (i.e. their marking) when lying in a place or when being moved by a transition.doi:10.1007/3-540-45397-0_5 fatcat:hhtt5vizj5hntllaxta2odb7zq
