Petri Net Markup Language
Petri Net Markup Language is an interchange format aimed at enabling Petri net tools to exchange Petri net models. PNML is an XML-based syntax for high-level Petri nets, which is being designed as a standard interchange format for Petri net tools.
It will end up being the second part of the ISO standard ISO/IEC 15909.
PNML grammar is publicly available on its reference .
The first part of this international standard, provides the mathematical definitions for high-level Petri nets.
These definitions are called the semantic model.
It also provides the graphical form definition, known as
High-level Petri Net Graph, and its mapping to the semantic model.
As of December 2004, the first part is an international standard.
