| Popis: | 91 Current information structure has been servicing the needs of printing and audio/video media, but its scope will be much broader because of the evolutional changes of application and development of electronic publication, user interface, and information media. Electronic publication is gaining in popularity, because the library collection policy “access” is replace by “ownership”. Commonly, an organization information system may have various data types and directory formats. It usually employs different metadata formats to represent the documents. Although the metadata system can cover the different formats of documents, it still exist the integration problems in various metadata systems. This may lower the performance of data processing and impede the information sharing. This thesis discusses the design of a dynamic metadata system framework that addresses: 1. Resolve the demand of multi-metadata co-existence. Propose a system structure of handling various metadata, centralizing the retrieving and interactive crossing authority control. 2. Design a novel electronic document delivery model. Explore the architecture, which XML technique to design the novel electronic document delivery for digital- or legacy- library system. Assist the user to query and retrieve information entity rapidly on the Web. 3. Use knowledge tree concept to organize metadata. Link related metadata to represent a knowledge tree for integrated knowledge of a specific domain. Allow users to access certain node of metadata and to get required information according to their personal needs and perception. |
