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：“在线危害”这一表述近年来因政治意愿的增长而浮现，旨在解决互联网及数字技术使用相关的伦理与社会问题。围绕在线危害的广阔领域汇聚了多学科、多部门及多组织的努力，同时为跨越固有边界带来了无数挑战与机遇。本文从一项由在线危害议程驱动的大型研究计划中汲取经验，探讨共同创制跨学科知识基础设施的过程。我们首先反思制图、分类与构建知识基础设施的内涵，并简要回顾文献中至今如何对在线危害及相关主题进行理论化与分类。基于我们自身共同创制在线危害图谱的经验，我们论证该图谱及制图过程发挥三种相互构成的功能：同时作为方法、媒介与挑战。我们总结开放性制图方法如何在伦理与政治敏感的研究领域中，尽管无法保证共识，却能促进富有成效的辩论与合作。最后，我们呼吁CSCW研究揭示并参与知识基础设施的多重时间性、社会生命与政治敏感性。
