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 are provided as network services by the use of policies, rules and network related metadata. Proposed metadata framework architecture is structured in two layers: metadata gateway and policy based service platform both provide open API to the next higher layer. Metadata gateway provides integrated metadata retrieval capability across various metadata descriptions, and policy based service platform provides specific functions common to content delivery such as QoS control and CDN management.
