Accumulation, storage and obtainment of generalized net tokens characteristics history

In this paper is represented one idea for an extension to the existing software for generalized net (GN) models simulation. Given solution for storing of the characteristics of the tokens during their movements through the GN-models improves the existing GN-interpreter. The software tool is designed to be the independent central component of GN enabled applications. In this paper the idea for adding a new functionality is presented and the bases for storing tokens characteristics development are laid.
