AI总结:

Keck天文台档案库推出ODAP Web应用,利用React与WebSocket实现观测数据及元数据在归档后近实时流式传输给授权研究团队,并总结其设计、集成与使用情况。

摘要:

W. M. Keck天文台档案库(KOA)发布了观测者数据访问门户(ODAP),这是一款Web应用程序,可将近乎实时的W. M. Keck天文台天文数据传送给世界各地已排期项目的首席研究员及其合作者。数据文件及其关联元数据在写入磁盘并存档到KOA后不久,便会流式传输到用户的桌面计算机。ODAP用户界面采用React构建,并使用WebSocket协议在KOA与用户之间流式传输数据。本文描述了该工具的设计、遇到的挑战,展示了ODAP如何集成到Keck观测模型中,并提供了使用指标分析。

英文摘要:

The W. M. Keck Observatory Archive (KOA) has released the Observers Data Access Portal (ODAP), a web-application that delivers astronomical data from the W. M. Keck Observatory to the scheduled program's principal investigator and their collaborators anywhere in the world in near real-time. Data files and their associated metadata are streamed to a user's desktop machine moments after they are written to disk and archived in KOA. The ODAP User Interface is built in React and uses the WebSocket protocol to stream data between KOA and the user. This document describes the design of the tool, challenges encountered, shows how ODAP is integrated into the Keck observing model, and provides an analysis of usage metrics.
