In hydrologic research, there is a need to manage, archive, and publish data in a discoverable way to increase data reuse, transparency, and reproducibility. Multidimensional space-time data are commonly used in hydrologic research, and systems are needed for sharing and exchanging such data. Simply exchanging files may result in loss of metadata information and can be challenging when files are large. We developed an approach to manage, share, and publish multidimensional space-time data in HydroShare, a next generation hydrologic information system and domain specific repository. This paper presents the design, development, and testing of this approach. We selected the Network Common Data Form (NetCDF) as the underlying data model. We defined specific metadata elements to store and manage multidimensional space-time data. We adopted and adapted existing software to automatically harvest, support entry of metadata, and establish standardized data services to serve and enhance access to the datasets shared in HydroShare.

在水文研究中，需要以一种可发现的方式来管理，存档和发布数据，以提高数据的重复使用性，透明度和可重复性。多维时空数据通常用于水文学研究，并且需要用于共享和交换此类数据的系统。仅仅交换文件可能会导致元数据信息丢失，并且在文件很大时可能具有挑战性。我们开发了一种在HydroShare，下一代水文信息系统和特定领域存储库中管理，共享和发布多维时空数据的方法。本文介绍了这种方法的设计，开发和测试。我们选择了网络通用数据表单（NetCDF）作为基础数据模型。我们定义了特定的元数据元素来存储和管理多维时空数据。
