When user is about to start participating in a business process, he can go to the Dashboard and request to view a declaration about the data needs and other participants of the business process. Such declaration is prepared from the Business Process Model.
User can then edit his policy to allow the data needs to be satisfied and shared with the other participants of the process.
Each business process model can be viewed as a high level service and can be described by a service type. This makes it possible to discover Service Providers who implement the business process.
