As Web services become more and more popular, how to manage multimedia Web services provisioning and delivery remains challenging. This chapter presents a componentization model to support quality of service (QoS)-centered, context-aware multimedia Web services delivery, which seamlessly incorporates cutting-edge technologies relating to Web services. A multimedia Web service is divided into control flow and data flow, each being delivered via different infrastructures and channels. We also propose enhancements to Simple Object Access Protocol (SOAP) and Composite Capability/Preference Profiles (CC/PP) protocols to improve their flexibility to serve multimedia Web services. In addition, we present a set of experiments to show how our service-oriented componentization model can support efficient delivery and management of multimedia Web services.
