It is an experimental language intended for parallel and distributed systems modelling and prototyping. The basic concepts of OOPN and PNtalk were defined in 1993 by Vladimir Janousek . An experimental implementation of the PNtalk System comprising an OOPN browser and a debugger has been made available mainly thanks to Tomas Vojnar who has implemented key parts of the system. Current research activities within the PNtalk project comprise developing analysis and verification methods to be used over OOPNs, and working on alternative forms of the PNtalk system implementation, including its distributed version .
