Abstract
We present a new programming model targeted at collaborative business process integration applications. This model is based on object-oriented technology, but elevates the programming model to cover a new breed of business applications that are currently evolving. These applications are differentiated by their strong emphasis on "collaborations" in which a set of "collaborators" works together to attain business objectives, and on integration where new functionality is derived by integrating legacy systems with new components and applications. We propose two new modeling artifacts, ADoc (adaptive document) and collaboration, to model this class of applications. We present an in depth analysis of this programming model. We conclude by discussing our experience of using this model in real world applications.
