Summary: 
This paper proposes a coordinator for workflow management systems (WFMSs). It is a basic module for developing WFMSs. It is also a coordinator to coordinate multiple WFMSs. The coordinator provides functions to facilitate executing workflows and to ensure secure access of workflow information. Facilitating workflow execution is well-known, but ensuring secure access of workflow information is identified as important only recently. Although many models ensure secure workflow information access, they fail to offer the features we need. We thus developed a new model for the control. This paper presents the coordinator its access control model.
