Āhau is a FOSS project from Aotearoa New Zealand, built to meet the data needs of Māori. This talk will share insights from thinking in a less Eurocentric way about data, and how the need for data sovereignty has lead us to p2p data models, which fit really well with human-focused systems. Over the last 3 years, we've built a desktop application on secure scuttlebutt that is currently in use by hapū and iwi (tribal groups) to record family histories and create tribal registries.
