MAS organisations to adapt your composite service

Adapting composite web-services is a concern of many researchers from the services community and a requirement of the industry. We propose the CASAS (Composable, Adaptive, Service, Agent System) framework that provides mechanisms to monitor and pro-actively adapt composite services. The framework integrates concepts of Service Oriented Computing and Agent Organisations, offering monitoring and adaptation mechanisms to deal with adaptation in service compositions. CASAS is an improvement on related work in that it offers a high-level model that allows the definition and enforcement of global constraints for the service composition. We explain CASAS in detail and conclude by showing how one can use it to create an adaptable composite service written in the Business Process Execution Language (BPEL).status: publishe
