Many tools for online collaboration, information and file sharing are currently employed to facilitate the process of online education. However, as stated in [14] the existing E-learning environments are not mature enough and only a small set of them provide functionality for defining reusable learning entities, reliable publishing and republishing mechanisms and possibilities for the teachers to give feedback to or receive feedback from the E-students. In order to improve E-learning experience [14] presents PeU 2.0, a system that enables the graphical representation and editing of the learning workflow without the execution environment of a workflow management system. The present paper examines the current executability of Petri Nets and gives a mapping of the visual elements in the PeU 2.0 graphs onto Petri Net structures. An interesting approach is introduces for the physical execution of the Petri Nets.
