SNet is a prototype environment supporting the representation and dynamic evaluation of designs for social networks comprising human, hardware, and software agents. The environment employs metadata management technology to integrate an extended version of the i* formalism for static network modeling with the ConGolog logic-based activity simulator. The paper defines the formal mappings necessary to achieve the integration and describes an operational prototype demonstration. SNet’s intended application domain is requirements management and mediation support for inter-organizational and embedded process systems, as well as simulation support for inter-organizational studies e.g. in hightech entrepreneurship networks.
