ABSTRACT

The French Critical Zone research infrastructure, OZCAR-RI, gathers 20 observatories sampling various compartments of the critical zone, each having developed their own data management and distribution systems. A common information system (Theia/OZCAR IS) was built to make their in situ observation FAIR (findable, accessible, interoperable, reusable). The IS architecture was designed after consultation of the users, data producers and IT teams involved in data management. A common data model based on various metadata standards was defined to create information fluxes between observatories’ ISs and the Theia/OZCAR IS. Controlled vocabularies were defined to develop a data discovery web portal offering a faceted search with various criteria, including variables names and categories that were harmonized in a thesaurus published on the web. This paper describes the IS architecture, the pivot data model and open-source solutions used to implement data discovery, and future steps to implement data downloading and interoperability services.

摘要

法国关键区研究基础设施 OZCAR-RI 聚集了 20 个观测站，对关键区的各个隔间进行采样，每个观测站都开发了自己的数据管理和分发系统。建立了一个共同的信息系统（Theia/OZCAR IS）来使他们就地观察 FAIR（可查找、可访问、可互操作、可重用）。IS 架构是在咨询了用户、数据生产者和参与数据管理的 IT 团队后设计的。定义了一个基于各种元数据标准的通用数据模型，以在天文台的 IS 和 Theia/OZCAR IS 之间创建信息通量。定义受控词汇表是为了开发一个数据发现门户网站，该门户网站提供具有各种标准的分面搜索，包括在网络上发布的同义词库中协调的变量名称和类别。本文描述了 IS 体系结构、用于实现数据发现的枢轴数据模型和开源解决方案，以及实现数据下载和互操作性服务的未来步骤。
