Insights into Web Service Orchestration and Choreography

As the Web service domain is a fast growing and equally fast changing environment, this paper tries to provide a critical snapshot of currently available standards, particularly focusing on Web service orchestration and choreography. The trend over the last few years in the Web services area firmly points towards seamless business logic integration and inter-enterprise collaboration. In order to reach these business goals, both technological and conceptual advances are required; some already have proven their viability, others still have to be made. Among them, Web service orchestration and choreography are of crucial importance, but still lack a widely agreed on development framework comprising both technological and conceptual aspects. Besides discussing problems and solutions regarding orchestration and choreography of Web services, especially from a conceptual point of view, this paper further tries to highlight mutual dependencies existing among orchestration and choreography.
