This paper shares experiences with digital tools in the context of ethnological collections and discusses the challenges of accommodating different knowledge practices in collaboration with heritage communities. Departing from the Sharing Knowledge project (2014-2020), which took place in the Ethnologisches Museum (Staatliche Museen zu Berlin/ Stiftung Preußischer Kulturbesitz), the chapter argues that evaluating the weight of infrastructural inertia and exploring infrastructures’ operations – i.e., decoding the master narratives and exclusion mechanisms behind museum knowledge practices – are crucial steps to develop tools and tactics to circumvent and undermine this very inertia. While the first part of the paper pays critical attention to this case study, the second proposes new methodologies to devise infrastructures that embrace relationality and plurality.
