This paper proposes metadata framework architecture for policy based content delivery over network. It also addresses policy based QoS control and CDN management as implementation examples of proposed architecture. In broadband ubiquitous networks, this architecture enables content aware QoS control and automatic content adaptation to usage environment that… (More)
For supporting a variety of museums and satisfying a variety of user requirements to access the museums information, an integrated access scheme is discussed and proposed. The integration is based on a proposed layered framework. Some experiments on a prototype system of museum information access are shown for layer 1 and layer 2 of the framework.
