Résumé
"This paper presents TERRA and ACQUA3 two mechanisms that support adaptable definition and execution ofworkflows. Given the specification of a process as a workflow (activities, flow, agents and behaviour) TERRA generates a graphrepresenting the workflow. Such a graph is used for verifying structure correctness and termination of a workflow specification.Once verified, TERRA generates and stores structures (objects, events, reactions) necessary for executing a workflow. ACQUAexecutes workflows according to a parametric behaviour model that represents workflow execution policies in terms ofdimensions associated to values. ACQUA is supported by event based communication mechanisms for interacting with agentsthat participate in the execution of workflows activities. Finally, TERRA and ACQUA provide mechanisms for modifying thestructure of a workflow and its associated behaviour."
