The Petri Net Markup Language (PNML) is an XML-based interchange format for Petri nets. In order to support different versions of Petri nets and, in particular, future versions of Petri nets, PNML allows the definition of Petri net types. Due to this flexibility, PNML is a starting point for a standard interchange format for Petri nets. This paper discusses(More)
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(More)
Process mining includes the automated discovery of processes from event logs. Based on observed events (e.g., activities being executed or messages being exchanged) a process model is constructed. One of the essential problems in process mining is that one cannot assume to have seen all possible behavior. At best, one has seen a representative subset.(More)
More and more information about processes is recorded by information systems in the form of so-called “event logs”. Despite the omnipresence and richness of these event logs, most software vendors have been focusing on relatively simple questions under the assumption that the process is fixed and known, e.g., the calculation of simple performance metrics(More)
