The purpose of this paper is to boost multidisciplinary research by the building of an integrated catalogue or research assets metadata. Such an integrated catalogue should enable researchers to solve problems or analyse phenomena that require a view across several scientific domains.,There are two main approaches for integrating metadata catalogues provided by different e-science research infrastructures (e-RIs): centralised and distributed. The authors decided to implement a central metadata catalogue that describes, provides access to and records actions on the assets of a number of e-RIs participating in the system. The authors chose the CERIF data model for description of assets available via the integrated catalogue. Analysis of popular metadata formats used in e-RIs has been conducted, and mappings between popular formats and the CERIF data model have been defined using an XML-based tool for description and automatic execution of mappings.,An integrated catalogue of research assets metadata has been created. Metadata from e-RIs supporting Dublin Core, ISO 19139, DCAT-AP, EPOS-DCAT-AP, OIL-E and CKAN formats can be integrated into the catalogue. Metadata are stored in CERIF RDF in the integrated catalogue. A web portal for searching this catalogue has been implemented.,Only five formats are supported at this moment. However, description of mappings between other source formats and the target CERIF format can be defined in the future using the 3M tool, an XML-based tool for describing X3ML mappings that can then be automatically executed on XML metadata records. The approach and best practices described in this paper can thus be applied in future mappings between other metadata formats.,The integrated catalogue is a part of the eVRE prototype, which is a result of the VRE4EIC H2020 project.,The integrated catalogue should boost the performance of multi-disciplinary research; thus it has the potential to enhance the practice of data science and so contribute to an increasingly knowledge-based society.,A novel approach for creation of the integrated catalogue has been defined and implemented. The approach includes definition of mappings between various formats. Defined mappings are effective and shareable.

构建集成的增强型虚拟研究环境元数据目录

本文的目的是通过构建综合目录或研究资产元数据来促进多学科研究。这种集成目录应该使研究人员能够解决需要跨多个科学领域的视图的问题或分析现象。集成不同电子科学研究基础设施 (e-RI) 提供的元数据目录有两种主要方法：集中式和分布式。作者决定实施一个中央元数据目录，该目录描述、提供对参与系统的多个 e-RI 资产的访问和记录操作。作者选择了 CERIF 数据模型来描述可通过集成目录获得的资产。对 e-RI 中使用的流行元数据格式进行了分析，流行格式与 CERIF 数据模型之间的映射已使用基于 XML 的工具进行定义，用于描述和自动执行映射。已经创建了研究资产元数据的集成目录。来自支持 Dublin Core、ISO 19139、DCAT-AP、EPOS-DCAT-AP、OIL-E 和 CKAN 格式的 e-RI 的元数据可以集成到目录中。元数据存储在集成目录中的 CERIF RDF 中。已经实现了用于搜索此目录的门户网站。目前仅支持五种格式。但是，未来可以使用 3M 工具定义其他源格式和目标 CERIF 格式之间映射的描述，这是一种基于 XML 的工具，用于描述 X3ML 映射，然后可以在 XML 元数据记录上自动执行。因此，本文中描述的方法和最佳实践可以应用于未来其他元数据格式之间的映射。,集成目录是 eVRE 原型的一部分，它是 VRE4EIC H2020 项目的结果。集成目录应该促进多学科研究的表现；因此，它有可能增强数据科学的实践，从而为日益以知识为基础的社会做出贡献。已经定义并实施了一种创建综合目录的新方法。该方法包括定义各种格式之间的映射。定义的映射是有效且可共享的。综合目录应提高多学科研究的绩效；因此，它有可能增强数据科学的实践，从而为日益以知识为基础的社会做出贡献。已经定义并实施了一种创建综合目录的新方法。该方法包括定义各种格式之间的映射。定义的映射是有效且可共享的。综合目录应提高多学科研究的绩效；因此，它有可能增强数据科学的实践，从而为日益以知识为基础的社会做出贡献。已经定义并实施了一种创建综合目录的新方法。该方法包括定义各种格式之间的映射。定义的映射是有效且可共享的。
