Abstract:
1. A method for coordinating execution of compound Web services over a network, the method comprising the computer-implemented steps of: receiving a request for a particular compound Web service that uses output from at least a first Web service and a second Web service; reading dependency information specific to the particular compound Web service, wherein the dependency information specifies a sequence in which a plurality of modules must be executed to perform the particular compound Web service; wherein at least one of the plurality of modules is from a group consisting of: wherein properties of the plurality of modules are defined and set specifically for the particular compound Web service at service design time and persist through service runtime; based on the dependency information, coordinating execution of the plurality of modules in the specified sequence, wherein the plurality of modules includes a first service execution module having a module property that is set specifically for coordinating execution of the first Web service and a second service execution module having a module property that is set specifically for coordinating execution of the second Web service; controlling execution of the particular compound Web service using the properties of the plurality of modules defined and set for the particular compound Web service; and generating a result of the compound Web service based on the output from the first and second Web services.
