Indigenous data sovereignty is the right of Indigenous peoples to govern data about their communities, lands, and members. In Canada the First Nations principles of OCAP, standing for ownership, control, access, and possession, set out that First Nations own their information, control how it is used, decide who may access it, and may hold it physically, with related frameworks for Inuit and Metis research and the international CARE principles alongside FAIR. A well-built platform enforces these commitments in the system, with community-controlled access rules, agreed data locations, and audit logs, rather than relying on a policy document.
