Orchestration of public administration services with a use of semantic technologies
Marek Skokan, Peter Bednár · 2008
Currently, public administration services are being transformed into electronic. In such state, service consumers can solve their life event situations by going thru sequence of services where combination of traditional and electronic services is might occur. Service choreography is known as observable behaviour of one service from client's point of view. But there is a need to describe also how the overall functionality of the service is achieved in terms of cooperation with the other services (a full execution mechanism) is known as orchestration. Execution mechanism that is able to interpret (chosen) WSMO choreography and orchestration description is based on abstract state machines for WSMO specification. In principle, this implementation is not suitable in case there is a need to navigate user during the process execution. To overcome this problem, an alternative solution based on Cashew workflow language was proposed.
