Paul Robinson, >We can tweak the spec and the technology to put ownership back > where it belongs, but it needs some thought. Related papers in word format were sent to you. In fact, our system can be regarded as an information shared platform. To integrated different kinds of information resources, DRIS provides two methods. 1 distributed search interface. Corresponding protocol defines a platform-independent search interface and a collection description standard for heterogeneous information resources. An I-D "information retrieval protocol for digital resources" has been proposed. 2 metadata harvesting. It will define a standard metadata format that can be compatible with most database system. A protocol based some available opening standard like OAI will be proposed. As long as data source can provide the standard distributed search interface or comply with the metadata harvest format, they can all be brought into DRIS. But the web page is a special data source for its distributed character and large amount. To efficiently integrate web pages on Internet, DRIS will build a public opening web pages database, which will strictly comply with the principle of (organization level-conventional database system)-(sub country Internet level-metadata harvest system)-(country level-distributed system). All the work is carried out automatically. Like in the bottom level, we always don't wish to publish all our pages out of school network. Although all the pages is automatically downloaded and indexed by our DRIS server, we can limit the metadata of web pages sent to higher layer to ensure some special considerations. Other kinds of resources can select appropriate method and be imported in appropriate layer.
