    The aggregation methodology we propose in this paper automatically generates the service contract of a composite service from a set of contracts to be ggregated together with a data-flow mapping linking service parameters. Service contracts consist of (WSDL) signature, (OWL) ontology information, and (YAWL) behaviour specification. The aggregation process generates the workflow of the composite from the initial workflows by suitably adding control-flow constraints among their tasks due to data-flow dependencies among task parameters. After describing the whole methodology, we will also give an insight on our proof-of-concept Java prototype implementation of the aggregation process.
