Integrated Support Environment of Heterogeneous Metadata Schemas for Enhancing Interoperability of Information Resources

它被广泛地识别，因为元数据不仅具有关键的角色，而且还具有可访问性、保存、存档和更高的能力。元数据方案是由域设计和开发的。However，在网络信息环境中，在订购为新应用程序构建元数据模式时，我们需要重新使用和组合元数据方案在不同的域中开发自从scratch开发的元数据方案太快和不先进，以实现元数据互操作性。该研究的主要目标是建立一个环境以增强元数据方案的互操作性和可重用性，以及增强互操作性。网络信息环境中的元数据。在本研究中，我们研究了元数据模型和工具，以增强网络信息环境中的元数据和元数据方案的互操作性。在这个研究中，我们得到了以下的结果，我们收集了元数据方案和存储在元数据方案登记册中，以便按顺序调查功能要求的工具和模型，以增强元数据互操作性。我们已经为元数据词汇的维护构建了一个实验工具，可以很好地与注册表一起工作。我们根据都柏林核心应用概况的概念构建了一个层次模型的元数据方案。本模型说明书由元数据方案组成，并帮助元数据的有效互操作性和可重复性问题。我们构建了一个基本框架，用于将FRBR模型和可访问性元数据组合在一起，以适应用户及其环境的特征。在添加到这些结果中，我们在一个机构的网络档案系统上工作，一个分布式的存档系统，一个提高可靠性的网络档案系统，一个提高网络文档完整性的系统。

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.
