The PASSI and Agile PASSI MAS Meta-models Compared with a Unifying Proposal

A great number of processes for multi-agent systems have been presented in last years to support the different approaches to agentoriented design; every process is specific for a particular class of problems and it deals with a specific MAS meta-model. These differences produce inconsistences and overlaps: a MAS meta-model may define a term not referred by another, or the same term can be used with a different meaning. We think that the lack of a standardization may cause a significant delay to the diffusion of the agent paradigm outside research contexts, and working for this unification goal, it is also necessary to unambiguously define the terms of the agent model and their relationships thus obtaining a unified MAS meta-model. In this work we propose the PASSI MAS meta-model and the results of its adaptation to the needs of an agile process (agile PASSI).
