项目摘要

It is widely recognized that metadata plays crucial roles not only for discovery and description of resources but also for accessibility, preservation, archiving, and so forth. Metadata schemas have been designed and developed domain by domain. However, in the networked information environment, in order to build a metadata schema for a new application, we need to reuse and combine metadata schemas developed in different domains since development of metadata schemas from scratch is too expensive and disadvantageous for metadata interoperability.The primary goals of this sturdy are to build an environment to enhance interoperability and reusability of metadata schemas and to enhance interoperability of metadata in the networked information environment. In this study, we investigated metadata models and tools to enhance interoperability of metadata and metadata schemas in the networked information environment. In this study, we got the following results,・We collected metadata schemas and stored in the metadata schema registry in order to investigate the functional requirements for the tools and models to enhance metadata interoperability. We have built an experimental tool for maintenance of metadata vocabularies which works cooperatively with the registry.・We built a hierarchical model of metadata schemas based on the concept of application profiles of Dublin Core. This model clarifies components of metadata schemas and helps understand interoperability and reusability issues of metadata.・We built a basic framework to combine the FRBR model and accessibility metadata for flexible resource selection and adaptation of resources in accordance with the characteristics of users and their environments.In addition to these results, we worked on an institutional Web archive system, a distributed archival system for higher reliability, and a system to enhance integrity of Web documents.

人们普遍认识到，元数据不仅在资源的发现和描述方面发挥着至关重要的作用，而且在获取、保存和归档等方面也发挥着至关重要的作用。元数据模式是逐个领域地设计和开发的。然而，在网络信息环境下，为了构建一个新的元数据模式，需要对不同领域开发的元数据模式进行重用和组合，因为从头开始开发元数据模式的成本太高，不利于元数据的互操作。本研究的主要目标是建立一个环境，以增强元数据模式的互操作性和可重用性，并增强网络信息环境下元数据的互操作性。在这项研究中，我们研究了网络信息环境下的元数据模型和工具，以提高元数据和元数据模式的互操作性。在这项研究中，我们获得了以下结果：·我们收集了元数据模式并存储在元数据模式注册中心，以调查增强元数据互操作性的工具和模型的功能需求。我们已经建立了一个与登记册合作维护元数据词汇表的试验性工具。·基于Dublin Core应用配置文件的概念，构建了元数据模式的层次模型。该模型阐明了元数据模式的组件，并有助于理解元数据的互操作性和可重用性问题。·构建了将FRBR模型和可访问性元数据相结合的基本框架，以根据用户及其环境的特点灵活地选择和调整资源。此外，我们还开发了机构Web归档系统、可靠性更高的分布式归档系统和增强Web文档完整性的系统。
