This research project consisted of two parts: (1) research on how open data can make value chains more transparent; and (2) research on the roles of intermediaries in extending the reach of open data beyond the web. For Part 1, African Minds brought together stakeholders in a coffee value chain to discuss what data they own, what data they would like to have, and what data they are prepared to make open. This was done to explore whether open data can create a more transparent value chain that is beneficial to all stakeholders in the chain. Part 2 consisted of research on open data intermediaries in the agriculture sector in Ghana. The purpose of the research was to explore the positioning, functions and effects of intermediaries on the agricultural data ecosystem.
