omposition to address the need to be able to design and develop services SO that they may be deployed and adapted dynamically. A methodology is Service Delivery Platforms provided explaining how to use the policy-enabled concept to model, design, and deploy dynamic composition of services. We have explained its use for a tele- consultation case. We have presented an overview of the policy-based approach and we have explained how PESM diagrams and composition policies are used in the approach to specify the coordination of separately specified UML2.x collaborations. The PESM diagram allows us to emphasize the reusability of UML 2.x collaborations in service composition when combined with policy. We have demonstrated that the policy syntax can be used to specify composition policies for governing the chore- ography of elementary collaborations in dynamic composition of services. We have also demonstrated that local policy rules can be derived from global policy rules, and that local PESM diagrams can be derived from global PESM diagrams. We have explained how policy-enabled dynamic service composition can be deployed in the runtime system. We provide methodology explaining how to use the policy-enabled concepts to model, design, and deploy dynamic composition of services. The methodology describes how to use the models to specify, design, and deploy services that may be adapted and managed more easily to suit the changing requirements of users and enable more rapid deployment of services. Using policies and PESM diagrams makes the overall choreography flexible and adaptable, making this a promising approach to service composition. Policies are not just suitable for high-level abstraction/specification mechanisms, but also are a part of the deployment in the runtime system. The approach and methodology enables a large degree of variability in the services that the provider is able to offer to custom- ers. Policy is also used to enable dynamic choice between services to be offered. References 1. OMG. UML 2.2 Superstr
