This document discusses open data and issues around data sovereignty. It notes that open data is data that can be freely used and shared, subject to attribution. However, it also discusses problems that can arise from open data, such as inaccurate or flawed data being open, and marginalized groups having their data "colonized" and used against them. It advocates analyzing open data issues through a power differential lens, with those in power being more open and those without power having more control over their own data. The document also lists some organizations working on data sovereignty and indigenous data governance.
