The phrase "online harms" has emerged in recent years out of a growing political willingness to address the ethical and social issues associated with the use of the Internet and digital technology at large. The broad landscape that surrounds online harms gathers a multitude of disciplinary, sectoral and organizational efforts while raising myriad challenges and opportunities for the crossing entrenched boundaries. In this paper we draw lessons from a journey of co-creating a transdisciplinary knowledge infrastructure within a large research initiative animated by the online harms agenda. We begin with a reflection of the implications of mapping, taxonomizing and constructing knowledge infrastructures and a brief review of how online harm and adjacent themes have been theorized and classified in the literature to date. Grounded on our own experience of co-creating a map of online harms, we then argue that the map -- and the process of mapping -- perform three mutually constitutive functions, acting simultaneously as method, medium and provocation. We draw lessons from how an open-ended approach to mapping, despite not guaranteeing consensus, can foster productive debate and collaboration in ethically and politically fraught areas of research. We end with a call for CSCW research to surface and engage with the multiple temporalities, social lives and political sensibilities of knowledge infrastructures.

翻译：“网络危害”这一术语近年来因政治意愿的增强而兴起，旨在应对互联网及数字技术使用中涉及的伦理与社会问题。围绕网络危害的广阔领域汇集了多学科、多部门及多组织层面的努力，同时也为跨越长期存在的学科壁垒带来了诸多挑战与机遇。本文从一项以网络危害议程为核心的大型研究计划中，汲取了共同创建跨学科知识基础设施的经验教训。我们首先反思绘制图谱、构建分类体系及知识基础设施的内涵，并简要梳理文献中关于网络危害及邻近主题的理论化与分类现状。基于我们共同创建网络危害图谱的实践，我们进一步论证：该图谱及绘制过程履行了三种相互构成的功能——同时作为方法、媒介与挑战性议题。我们从开放式图谱构建方法中提炼经验，指出尽管该方法无法保证达成共识，却能促进伦理与政治敏感研究领域内的建设性辩论与合作。最后，我们呼吁CSCW研究领域揭示并关注知识基础设施在多重时间性、社会生命及政治敏感性方面的复杂动态。
