VieBOP: Extending BPEL Engines with BPEL4People

The need for integration of human interaction scenarios into BPEL processes lead to the formalisation of tasks and human roles. The specifications BPEL4People and WS- HumanTask introduce, among other definitions, a dedicated people activity that uses a task performed by a human as well as human roles that describe the relationship of people, processes and tasks. This work presents the architecture of Vienna BPEL for People (VieBOP), a new BPEL4People system that can be coupled with an arbitrary BPEL engine. We will evaluate the standards for BPEL4People and WS- HumanTask against goals as derived from the BPEL4People white paper and compare it to our work.
