The service-oriented approach is often used for modernizing information systems, offering solutions to create distributed and extensible platforms. Besides the technical characteristics, this transformation also implies changes from the point of view of human resources, i.e. new positions or roles, and even organization restructuring. This paper proposes a meta-modeling perspective for representing traditional and service-oriented organizational structures, as well as the transformations necessary for migrating from one to another. The authors apply the resulted meta-model and tools to a service-oriented hydrology system, modeling the new kinds of users required for the modernization of water pollution management at a large scale, with the goal of creating a cyber-infrastructure based on information processing services provided by multiple institutions.
