摘要: 资讯组织的对象、范围过去多是以印刷或视听媒体为主,然而,随着电子出版品、使用者介面与资讯媒体等应用与演变,使得资讯组织的范围更加扩大。而数位典藏、电子出版的普及与网路的发达,使得图书馆必须朝向数位化图书馆的领域发展,馆藏政策也从“拥有”转为“取得”为导向。但是,使用者有不同层级之资讯需求,如:检索需求、管理需求、保存需求等。不同的资讯亦有不同的文献特质,如地理资讯、博物馆资讯、科技文献、文学创作、音乐作品等,均各有其不同之文献结构、媒体特性、使用习性。
当传统以纸本资料为主要服务介面的图书馆,朝向电子化典藏的数位图书馆时,如何有效管理各种不同应用型态的metadata,提供使用者不同的资讯需求,以及系统一致性的资料存取与传递服务,便成了迫切需要解决的问题。
本论文主要是应用XML的结构原理,设计一个包含下列目的之动态metadata资讯系统框架:
1. 解决多种元资料并存的需求。提出一个能够处理多种metadata,并能集中管理、检索、和应用权威控制的系统结构。
2. 设计一个电子文献传递模式,应用XML技术探讨与设计一个符合电子图书馆与传统图书馆系统的电子文献传递架构,提供电子商务时代使用者藉由Web查询与即时取得原件的需求。
3. 使用知识树的概念组织元资料。将相关联的元资料串联在一个知识树下,提供特定领域知识的整合需求。提供使用者能够依据其个人需要直接切入知识树中任一节点,取得所需的资讯。
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.
