The Item Response Warehouse (IRW) is a collection and standardization of a large volume of item response datasets in a free and open-source platform for researchers. We describe key elements of the data standardization process and provide a brief description of the over 900 datasets in the current iteration of the IRW (version 28.2). We describe how to access the data through both the website and an API, and offer a brief tutorial with example R code illustrating how to download data from the IRW and use it in standard psychometric analyses. While we are continuing to develop the IRW, this presentation may help researchers utilize data from this resource for work in psychometrics and related fields.
项目反应仓库（IRW）是一个在免费开源平台上为研究人员收集和标准化大量项目反应数据集的平台。我们描述了数据标准化过程的关键要素，并简要介绍了IRW当前版本（28.2版）中的900多个数据集。我们描述了如何通过网站和应用程序编程接口（API）访问数据，并提供了一个简短的教程，其中包含示例R代码，说明了如何从IRW下载数据并将其用于标准心理测量分析。虽然我们仍在继续开发IRW，但本报告可能有助于研究人员利用该资源中的数据进行心理测量学及相关领域的研究工作。
