Read the record first先阅读记录
Start with the summary, geography and temporal coverage. They describe the intended frame of the data and are often more important than the file format.从摘要、地理范围和时间范围开始。它们描述数据的适用边界，往往比文件格式更重要。

A short guide to reading a record, checking its limits and making a responsible reuse of the files in this library.这是一份简短指南，帮助你阅读记录、检查数据边界，并负责任地复用本数据文库中的文件。
Trace the source追溯数据来源
Check the publisher, lineage, version and update date before joining a dataset with another source. If a field is derived, the documentation should say how.将数据集与其他来源结合前，先检查发布者、数据谱系、版本和更新时间。如果某个字段是派生的，文档应说明生成方式。
Respect the limits尊重数据边界
Resolution is not accuracy. A spatial layer can be useful for regional context while being inappropriate for a site-level decision. Use the license and limitations as part of your analysis notes.分辨率不等于准确度。空间图层可以用于区域背景，却不一定适合站点级决策。请将许可和局限性作为分析记录的一部分。
Cite the version you used引用你使用的版本
Each dataset page includes a copyable citation. Keep the version and access date with your work so another researcher can reconstruct the exact input.每个数据集页面都提供可复制的引用信息。请在研究中保留版本和访问日期，方便其他研究者重建完全一致的输入。
