On modelling adaptive service-oriented business processes

With the maturing of service technology, most of organizations are implementing their business processes using Web-services (shortly SO-BPs). Nevertheless, still challenging engineering problems are hindering highly adaptive and realistic composite services. We are proposing a stepwise approach for this purpose. First, we are adopting a fine-grained activity-based perception, where we govern the semantics of any activity using event-driven business rules. We then conceptualize such activity-centric rules as transient architectural connectors. In terms of service-oriented architecture, connector roles will be playing service interfaces, whereas their glues be capturing the service composition logic. We further sketch how this modelling approach can be implemented using the aspectual .Net environment.
