Reputation-Controlled Business Process Workflows

This paper presents a model solution for controlling the execution of BPEL business processes based on reputation constraints at the level of the services, the service providers and the BPEL workflow. The reputation constraints are expressed as part of an SLA and are then enforced at runtime by a reputation monitoring system. We use our model to demonstrate how trust requirements based on such reputation constraints can be upheld in a real world example of a distributed map processing defined as a BPEL workflow.
