Abstract: A method and system for specifying a data occurrence in a service-oriented architecture based environment. In particular the method defines a technique for specifying whether a data element of a service is optional or mandatory using information from the realization phase of the service in the development cycle. After a service specification phase of a service, a service interface is received and a service implementation is created. During a service realization phase, a data element of the service is determined to be sourced or not sourced by the service implementation. A data element being sourced by the service implementation is defined as a data element that is populated by the service implementation itself, whereas a data element not being sourced by the service implementation is defined as a data element populated by an application which consumes or invokes the service. If the data element is sourced, then the data element is determined to be optional. If the data element is not sourced, then the data element is determined to be mandatory. The data occurrence including an indication of whether the data element is optional or mandatory is displayed. The service specification phase is repeated and the service interface is modified based on the displayed data occurrence.
