Cover Story: The ubiquity of the Internet enabled the establishment of well-recognised online projects and knowledge bases. Online communities evolve around these projects that enhance and maintain their content, but these communities and their members are often ignored during the usage or analysis of the projects’ data. The systematic framework established in this publication enables a comparable analysis of online community members. Four contextual dimensions of effect on community members are identified: engagement and skill, physical location, digital location, community involvement and personal attributes. They influence many aspects of the data produced by community members. The framework is applied to the use case of OpenStreetMap mappers to assess the impact of community events on them and how these events influence the knowledge they produce. View this paper
