Mashups are getting more complex with the addition of rich-media and real-time services. The new research challenges will be how to guarantee the quality of the aggregated services and how to share them in a collaborative manner. This paper presents a metadata-based mashup framework in Next Generation Wireless Network NGWN which guarantees the quality and supports social interactions. In contrast to existing quality-assured approaches the proposed mashup model addresses the quality management issue from a new perspective through defining the Quality of Service QoS metadata into two levels fidelity user perspective and modality application perspective . The quality is assured from quality-aware service selection and quality-adaptable service delivery. Furthermore the mashup model is extended for users to annotate services collaboratively. The annotation occurs in two ways social tagging . rating and comments and QoS attributes . device type and access network etc. . In order to apply this network-independent metadata model into NGWN architecture we further introduce a new entity named Multimedia Mashup Engine
