Abstract: Traditional business process orchestration methods are usually too heavy-weight for situational applications. As an emerging Web 2.0 technology, Mashup enables end-users to draw upon contents, presentation or functionality logic from separated Web sources to create innovative applications. However, today researches about Mashup primarily focus on data integration and presentation integration instead of business process. This paper proposes a business process oriented Mashup model, in which business activities are encapsulated as browser-side components, and orchestrated together based on an event-driven Publish/Subscribe communication paradigm. The model introduces composite events to define the process behavior on browser side, and consequently shields end-users from traditional process constructs like conditional branching and looping, allowing them to create articulated business processes in a lightweight fashion.
