Within museums, archives, and libraries, there is increasing interrogation of established knowledge structures and their power to represent. Presenters in this Roundtable will share our experiences, frustrations, and aspirations working with the data systems surrounding institutionalized cultural collections as stewards and researchers. With the audience, we will begin a conversation exploring interest and direction for a collaborative survey of Collections Management Systems built for/with/around Indigenous Knowledge Systems (IKS) and values of knowledge sovereignty. The organizers approach this topic through our positionality as professionals of European settler and immigrant colonial heritage working with global collections of tangible and intangible culture. We believe a comparative survey could help decolonize broader museum and archival praxes by defining lessons from community-centered knowledge stewardship relevant to universalist CMS’s (for example, based on Library of Congress, Museum Nomenclature, Getty, and other controlled schema). There has been a vibrant proliferation of community-led initiatives in the space of IKS, both using open-source platforms (exp., Mukurtu, GRASAC GKS, Keeping Culture KMS) and bespoke systems (exp., Sqewlets Website Project). A synthetic understanding of these methods, data structures, values, and outcomes could clarify common strategies and improve critical data practices in both colonially- and community-held collections. This conversation builds on the American Alliance of Museums' 2018 report Words Matter: Lexicon Usage and Indigenous Cultural Belongings and other recent critical studies in the field.
