Web-services are self-contained, self-describing modular applications and can be soon as a newly emerging distributed computing model for the Web. There are two types of web-services: atomic and composite. A composite Web-Service can be described as a directed process graph that composes other atomic or composite Web-Services. A graph defines the order of execution among the nodes in the process model. In this paper we first discuss the relevant research issues required for outlining a web-service coordination model and compare them to existing coordination models. Furthermore we provide an e-learning scenario where we experiment with a team-enabled workflow management system to enact workflow-based web-services.
