5 CONCLUSIONS
In this paper, we have briefly described Gaia
methodology and we have presented its application to
design a set of agents to retrieve information of a set
of federated digital libraries. This design has been
proposed as an alternative to have access to these
heterogeneous and distributed sources of information.
All the stages and the different of models were
included.
Gaia methodology was chosen due to its
adaptability characteristics in such a way that can be
applied to a wide range of agent-based systems. The
design of the agents presented in this paper with this
methodology provides us of a detailed description of
the system in such a way that the different kinds of
agents can be implemented easily; likewise, it can be
perceived as a reliable document to support system
maintenance. According to the requirements
statement, this design can be a base for the stages of
validation, verification and test.
