Studies on Open Source Software (OSS) developer communities have long stated that there is a relationship between community structure and tasks carried out by project members. This relationship has been exemplified by the onion model, which has been instrumental in understanding self‐coordination in OSS projects. Despite its ubiquity, there is a lack of empirical evidence to validate the relative position of each task cluster within the onion model. In this study, we map out the community structure of a large open source project and observe its bug‐fixing patterns to explore the relationship between tasks and structure. Our study makes three significant contributions. First, we find no empirical evidence to support the structural location of bug‐fixing tasks in the onion structure. Second, we find empirical evidence to support the core‐periphery continuum model linking an actor’s coreness to problem‐solving ability. Third, our results suggest that the importance and location of each task within the core‐periphery structure evolve over time. These findings add clarity to the community structure and their implications for the management and coordination of collaborative innovation projects.

开源软件中基于任务的结构：重新审视洋葱模型

开放源软件（OSS）开发人员社区的研究长期以来一直指出，社区结构与项目成员执行的任务之间存在联系。洋葱模型已证明了这种关系，该模型有助于理解OSS项目中的自我协调。尽管它无处不在，但缺乏经验证据来验证洋葱模型中每个任务集群的相对位置。在本研究中，我们绘制了一个大型开源项目的社区结构，并观察其错误修复模式以探索任务与结构之间的关系。我们的研究做出了三个重要贡献。首先，我们找不到经验证据来支持错误修复任务在洋葱结构中的结构位置。第二，核数，以解决问题的能力。第三，我们的结果表明，核心-外围结构中每个任务的重要性和位置会随着时间而发展。这些发现为社区结构及其对协作创新项目的管理和协调的含义增加了清晰度。
