Abstract
A delegation metasystem for composite services is described, where a composite service is a service which calls other services during its operation. In an embodiment, the composite service is defined using generic descriptions for any services (and their access control models) which may be called by the composite service during operation. At run time, these generic descriptions and potentially other factors, such as the user of the composite service, are used to select actual available services which may be called by the composite service and access rights for the selected services are delegated to the composite service. These access rights may subsequently be revoked when the composite service terminates.
