Development of a Multilingual Metadata Registry for Dublin Core

在互联网环境中，有许多社区根据其社区特定的需求定义元数据模式。另一方面，元数据互操作性是互联网和数字图书馆的一个关键问题。元数据模式注册是元数据模式共享的一个重要功能，它提供元数据模式的权威信息。本研究对元数据模式注册进行了研究，并构建了一个元数据模式注册原型系统，该系统提供了都柏林核心的多语言模式信息。注册表存储并提供元数据词汇表，其中包含定义资源属性的术语和定义元数据值的类（或类型）的术语。在本研究中，我们与欧洲和美国的都柏林核心元数据计划的研究人员合作，注册表存储了用资源描述框架（RDF）模式语言表示的元数据模式。截至2003年3月，登记处有一套参考说明，其中包括15个简单都柏林核心要素的英文版和22种语言的译文，以及都柏林核心限定词的英文版和日文版。除了注册表的开发之外，通过本研究，我们还获得了支持元数据软件工具开发的软件模式，例如，元数据编辑器和检索工具，从一个元数据模式和一个框架，以支持跨多个元数据模式的元数据收获。我们在国际会议上提交了关于登记册和相关工作的论文。

In the Internet environment, there are a number of communities which defines metadata schema based on their community-specific requirements. On the other hand, metadata interoperability is a crucial issue in the Internet and for digital libraries. Metadata schema registry, which provides authoritative information of metadata schemas, is widely recognized as an important function to share metadata schemaIn this research, we investigated metadata schema registry and constructed a prototype of a metadata schema registry which provides schema information of Dublin Core expressed in multiple languages. The registry stores and provides a metadata vocabulary which contains terms to define resource properties and those to define classes (or types) of metadata values. In this research, we collaborated with researchers in Europe and USA who have been involved in Dublin Core Metadata Initiative.The registry stores metadata schemas expressed in Resource Description Framework (RDF) schema language. As of March 2003, the registry has a set of reference descriptions of 15 Simple Dublin Core elements in English and translations in 22 languages, Dublin Core qualifiers in English and Japanese. In addition to the development of the registry, through this research, we obtained a software mode to support development of software tools for metadata, e.g., metadata editors and retrieval tools, from a metadata schema and a framework to support metadata harvesting across multiple metadata schemas. We have presented papers on the registry and related works at international conferences.
