Abstract

In recent years, China's advanced light sources have entered a period of rapid construction and development. As modern X-ray detectors and data acquisition technologies advance, these facilities are expected to generate massive volumes of data annually, presenting significant challenges in data management and utilization. These challenges encompass data storage, metadata handling, data transfer and user data access. In response, the Data Organization Management Access Software (DOMAS) has been designed as a framework to address these issues. DOMAS encapsulates four fundamental modules of data management software, including metadata catalogue, metadata acquisition, data transfer and data service. For light source facilities, building a data management system only requires parameter configuration and minimal code development within DOMAS. This paper firstly discusses the development of advanced light sources in China and the associated demands and challenges in data management, prompting a reconsideration of data management software framework design. It then outlines the architecture of the framework, detailing its components and functions. Lastly, it highlights the application progress and effectiveness of DOMAS when deployed for the High Energy Photon Source (HEPS) and Beijing Synchrotron Radiation Facility (BSRF).

DOMAS:先进光源的数据管理软件框架。
近年来,我国先进光源进入快速建设和发展时期。随着现代 X 射线探测器和数据采集技术的发展,这些设施预计每年将产生海量数据,给数据管理和利用带来巨大挑战。这些挑战包括数据存储、元数据处理、数据传输和用户数据访问。为此,设计了数据组织管理访问软件(DOMAS)作为解决这些问题的框架。DOMAS 囊括了数据管理软件的四个基本模块,包括元数据目录、元数据采集、数据传输和数据服务。对于光源设施来说,建立数据管理系统只需要在 DOMAS 中进行参数配置和最少的代码开发。本文首先讨论了中国先进光源的发展以及与之相关的数据管理需求和挑战,从而引发对数据管理软件框架设计的重新思考。然后,本文概述了该框架的架构,详细介绍了其组件和功能。最后,重点介绍了 DOMAS 在高能光子源(HEPS)和北京同步辐射设施(BSRF)中的应用进展和效果。
