An active XML (AXML) document contains tags representing calls to Web services. Therefore, retrieving its contents consists in materializing its data elements by invoking the embedded service calls in a P2P network. In this process, the result of some service calls can be used as input of other calls. Also, usually several peers provide each requested Web service, and peers can collaborate to invoke these ser-vices. This often implies a huge search space of many equivalent materialization alternatives, each with different performance.
