An extendible Petri net model for Memex-like applications

A self-modifiable color Petri net model (SMCPN) that has multimedia synchronization capability is proposed in this paper. By introducing color tokens associated with basic commands, this model can handle user interaction flexibility. By combining numbers with the color tokens, SMCPN allows iteration to be modeled and hence is able to reduce the graph sizes of synchronous playback models while allowing greater details to be shown. SMCPN can also be used in the design and modeling of a multimedia tool with Memex functions like forward, backward, and trail history functions in a Web browser.
