如果没有适当的储存库来支持所有相关的天文数据产品，数据可能会陷入黑暗：看不见，无法用于未来的参考和再利用。这类数据中的一些数据是遗留或旧数据，但较新的数据集也往往未经管理，可能仍然是黑暗的。本文描述了Astrolabe的设计动机和开发，Astrolabe是一个网络基础设施项目，它提出了一系列社区建议，用于定位和确保长期管理黑暗或其他风险数据和集成计算。本文还介绍了一系列的社区讲习班，告知创建星盘的成果。据这些讲习班的参与者说，目前存在许多天文学暗数据，这些数据在其他地方没有得到管理，还有一些软件只能由少数人执行，因此由于计算平台的变化而变得无法使用。利用不属于现有观测站和空间使命项目范围的综合数据和计算资源，可以更好地解决天文学研究问题和挑战。作为一种解决办法，等高仪系统的设计旨在开发管理天文数据的新资源。该项目基于CyVerse网络基础设施技术，是亚利桑那大学和美国天文学会之间的合作。总体而言，该项目旨在通过利用现有网络基础设施资源支持开放获取研究数据，并通过以可计算格式向天文学界提供可能有用的数据来促进科学发现。
Where appropriate repositories are not available to support all relevant astronomical data products, data can fall into darkness: unseen and unavailable for future reference and reuse. Some data in this category are legacy or old data, but newer data sets are also often uncurated and could remain dark. This paper provides a description of the design motivation and development of Astrolabe, a cyberinfrastructure project that addresses a set of community recommendations for locating and ensuring the long-term curation of dark or otherwise at-risk data and integrated computing. This paper also describes the outcomes of the series of community workshops that informed creation of Astrolabe. According to participants in these workshops, much astronomical dark data currently exist that are not curated elsewhere, as well as software that can only be executed by a few individuals and therefore becomes unusable because of changes in computing platforms. Astronomical research questions and challenges would be better addressed with integrated data and computational resources that fall outside the scope of existing observatory and space mission projects. As a solution, the design of the Astrolabe system is aimed at developing new resources for management of astronomical data. The project is based in CyVerse cyberinfrastructure technology and is a collaboration between the University of Arizona and the American Astronomical Society. Overall, the project aims to support open access to research data by leveraging existing cyberinfrastructure resources and promoting scientific discovery by making potentially useful data available to the astronomical community, in a computable format.
