A MVC Framework for Policy-Based Adaptation of Workflow Processes: A Case Study on Confidentiality
Most work on adaptive workflows offers insufficient flexibility to enforce complex policies regarding dynamic, evolvable and robust workflows. In addition, many proposed approaches require customized workflow engines. This paper presents a portable framework for realistic enforcement of dynamic adaptation policies in business processes. The framework is based on the Model-View-Controller (MVC) pattern, commonly used for adding dynamism to web pages. To enhance reusability, the authors' approach supports separation of adaptation logic from the functional workflow and modularization of workflow tasks in reusable aspects. The main idea is to design a workflow process as a template, where tasks can be specified on an abstract level.
