  abstract =	 {The Petri Net Markup Language (PNML) is an XML-based
                  interchange format for Petri nets. In order to
                  support di erent versions of Petri nets and, in
                  particular, future versions of Petri nets, PNML
                  allows the de nition of Petri net types. Due to this
                  exibility, PNML is a starting point for a standard
                  interchange format for Petri nets. This paper
                  discusses the design principles, the basic concepts,
                  and the underlying XML technology of PNML. The main
                  purpose of this paper is to disseminate the ideas of
                  PNML and to stimulate discussion on and
                  contributions to a standard Petri net interchange
                  format.},
