The Petri Net Markup Language (PNML) is an XML-based interchange format for Petri nets. PNML supports any version of Petri net since new Petri net types can be defined by so-called Petri Net Type Definitions (PNTD).

In this paper, we present the syntax and the semantics of PNML as well as the principles underlying its design. Moreover, we present an extension called modular PNML, which is a type independent module concept for Petri nets.
