A framework is proposed that would create, use, communicate, and distribute information whose organizational dynamics allow it to perform a distributed cooperative enterprise also in public environments over open source systems. The approach assumes the Web services as the enacting paradigm, possibly over a grid, to formalize interaction as cooperative services on various computational nodes of a network. A framework is thus proposed that defi nes the responsibility of e-nodes in offering services and the set of rules under which each service can be accessed by e-nodes through service invocation. By discussing a case study, this chapter details how specifi c classes of interactions can be mapped into a service-oriented model whose implementation is carried out in a prototypical public environment.
