A method and system for specifying a data occurrence in a service-oriented architecture based environment. 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. 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. |
