ABSTRACT Protocols have been utilised as a tool to build dialogue on the management of Indigenous knowledges in a library and archive context. This paper discusses how the Aboriginal and Torres Strait Islander Protocols for Libraries, Archives and Information Services (ATSILIRN [n.d.] Protocols for Libraries Archives and Information Services. http://atsilirn.aiatsis.gov.au/protocols.php) could guide Wikimedia projects and Wikipedia and Wikidata editors to better describe Aboriginal and Torres Strait Islander content in a self-determined and culturally appropriate manner. Focussing specifically on questions of Description and Classification (Protocol 5), the paper examines the limitations of current metadata and Wikipedia practices and opportunities for embedding and being led by Aboriginal and Torres Strait Islander worldviews and principles. Overall, the article contributes to further understanding the challenges and opportunities of including Indigenous knowledges and perspectives in open access platforms.
