This work introduces NexusLIMS, an electron microscopy laboratory information management system designed and implemented by the Office of Data and Informatics and the Materials Science and Engineering Division at NIST for a multi-user electron microscopy co-op facility. NexusLIMS comprises network infrastructure, shared information technology resources, a custom software package to harvest and extract experimental information and construct experimental metadata records, and an intuitive web-based user-facing interface for searching, browsing, and examining research data. These metadata records conform to the Nexus Experiment schema, which is introduced in this work. The NexusLIMS suite of tools requires minimal input and adjustments to user behavior, instead relying on existing organizational procedures and the collection of information from a multitude of sources to construct a complete picture and record of a research experiment. The underlying infrastructure and design considerations for a multi-user data management system are discussed. The core codebase for NexusLIMS is made publicly available alongside this work, and its modular design encourages the adaptation of the presented methods at other research organizations.
这项工作介绍了NexusLIMS，这是一个由美国国家标准与技术研究院（NIST）数据与信息办公室以及材料科学与工程部门为多用户电子显微镜合作设施设计并实施的电子显微镜实验室信息管理系统。NexusLIMS包括网络基础设施、共享信息技术资源、一个用于收集和提取实验信息并构建实验元数据记录的定制软件包，以及一个直观的基于网络的面向用户的界面，用于搜索、浏览和检查研究数据。这些元数据记录符合本工作中介绍的Nexus实验模式。NexusLIMS工具套件只需最少的用户输入和行为调整，而是依靠现有的组织程序以及从多个来源收集的信息来构建研究实验的完整图景和记录。本文讨论了多用户数据管理系统的底层基础设施和设计考量。NexusLIMS的核心代码库随本工作一同公开，其模块化设计鼓励其他研究机构采用本文介绍的方法。
