Different efforts have been devoted to improve the original version of Gaia methodology. The more relevantis the official extension of Gaia, exploiting the organizational abstractions to provide clear guidelines for theanalysis and design of complex and open multiagent systems. However, now a day a successful designmethodology should include some other strategic factors like the support of a specific CASE tool tosimplify the work of the designer. Such a tool supporting the Gaia design process may facilitate theadoption of the methodology in the industrial arena. The present study introduces Gaia4E, a plug-in for theECLIPSE environment which covers all the phases of Gaia allowing agent engineers to produce anddocument the corresponding models
