With more and more media materials appear on the internet, it comes a sharp problem of how to manage these resources and how to search them efficiently. We construct a management system of media material for the reliable wideband network. According to a detailed analysis of the characteristic of media material queries, we proposed a hierarchical indexing mechanism based on XPath language to discover the resources that match a given query. Our system permits users to locate data iteratively even using scarce information. The description of materials is mapped onto the DHT index. Our indexing scheme has good properties such as space efficient, good scalability and resilient to arbitrary linking.
