Research methods and procedures are core aspects of the research process. Metadata focused on these components is critical to supporting the FAIR principles, particularly reproducibility. The research reported on in this paper presents a methodological framework for metadata documentation supporting the reproducibility of research producing Metal Organic Frameworks (MOFs). The MOF case study involved natural language processing to extract key synthesis experiment information from a corpus of research literature. Following, a classification activity was performed by domain experts to identify entity-relation pairs. Results include: 1) a research framework for metadata design, 2) a metadata schema that includes nine entities and two relationships for reporting MOF synthesis experiments, and 3) a growing database of MOF synthesis reports structured by our metadata scheme. The metadata schema is intended to support discovery and reproducibility of metal-organic framework research and the FAIR principles. The paper provides background information, identifies the research goals and objectives, research design, results, a discussion, and the conclusion.

翻译：研究方法和流程是研究过程的核心方面。聚焦这些组成部分的元数据对于支持FAIR原则（尤其是可重复性）至关重要。本文所述研究提出了支持金属有机框架（MOFs）研究可重复性的元数据文档方法论框架。该MOF案例研究运用自然语言处理技术从文献语料中提取关键合成实验信息，随后由领域专家开展分类活动以识别实体-关系对。研究成果包括：1）元数据设计的研究框架；2）涵盖九类实体及两种关系的MOF合成实验报告元数据方案；3）基于该方案构建的MOF合成报告动态数据库。该元数据方案旨在支持金属有机框架研究的发现与可重复性，并贯彻FAIR原则。本文提供了研究背景，明确了研究目标与任务、研究设计、研究结果、讨论及结论。
