Viewpoints Diagram: Towards an Innovative Diagram in the UML Language

This paper is to put forward a modeling of multi-view classes by making use of the Petri networks formalism. The object approach aims at modeling complex systems and allows to take into account the views of the different users of the system and their access rights. Thus, in the paper, they propose a representation of multi-view classes by Petri networks. This representation allows the administrator to follow the dynamic evolution of viewpoints and to monitor the access rights of users.
