Chapter 1 THEGAIAMETHODOLOGY: BASIC CONCEPTS AND EXTENSIONS

Abstract The Gaia methodology (Wooldridge et al., 2000) has been the rst com-plete methodology for the analysis and design of multiagent systems. However, the original version of Gaia suered from the limitations of be-ing suitable for the analysis and design of closed multiagent systems and of adopting non-standard notation techniques. For these reasons, several extensions to the basic Gaia methodology has been recently proposed. In this chapter, we summarize the key characteristics of the original Gaia methodology and present three extensions that have been proposed to Gaia to overcome its limitations and to make it more suitable for the development of open multiagent systems in complex environments
