Title: Workflow Description Language Comparison (thesis defense)
Abstract
This thesis compares the workflow description capabilities of the Business Process Management System IBM
WebSphere? Lombardi Edition and the Workflow Management System iTask. In IBM
WebSphere? Lombardi Edition the domain specific graphical Business Process Modeling Notation is used to model workflows. In iTask workflows are described in a textual workflow description language. iTask is a library that allows to extend the workflow description language of the iTask library. A workflow developer cannot extend the Business Process Modeling Notation in IBM
WebSphere? Lombardi Edition. The thesis checks if the power of the existing constructors of IBM
WebSphere? Lombardi Edition is sufficient to implement the workflow control flow patterns
here. All forty-three workflow control flow patterns have been implemented with the Business Process Modeling Notation as it is implemented in IBM
WebSphere? Lombardi Edition. Not all patterns have been implemented in iTask. Some constructors that are needed to implement a set of patterns are not implemented yet in the iTask library. The thesis shows that it is possible to extend the iTask workflow description language with additional combinators. Therefore a pattern has been integrated into the iTask workflow description language.
