The complex structural landscape of biological samples and their sensitivity to X-ray exposure leads to specific challenges in biological X-ray absorption spectroscopy (bio-XAS) research, which in turn has necessitated standardization of various aspects of bio-XAS data measurement, analysis and interpretation. The bio-XAS community is therefore well suited for the development of a data-reporting standard with the specific aim of creating a feedback loop for improving/standardizing data analysis protocols and optionally to make published data available to collaborators/researchers in a meaningful and quantitative format. The XIF (XAFS information file) reporting format presented here contains key experimental and analysis parameters, useful in developing a consistent platform for bio-XAS research worldwide. Such a reporting standard, enforced by the user community and publishing groups alike, can be an important step towards the standardization of data measurement and analysis techniques in bio-XAS.
生物样品复杂的结构特征以及它们对X射线照射的敏感性给生物X射线吸收光谱（bio-XAS）研究带来了特定挑战，这进而促使bio-XAS数据测量、分析和解释的各个方面都需要标准化。因此，bio-XAS领域非常适合制定数据报告标准，其具体目标是创建一个反馈循环，以改进/规范数据分析协议，并以有意义的定量格式向合作者/研究人员提供已发表的数据。本文介绍的XIF（XAFS信息文件）报告格式包含关键的实验和分析参数，有助于在全球范围内为bio-XAS研究建立一个统一的平台。这样一个由用户群体和出版团体共同执行的报告标准，可能是bio-XAS数据测量和分析技术标准化的重要一步。
