In this chapter of the recently published volume on State of Open Data, Tim Davies and Sumandro Chattapadhyay discuss how the lessons from the land ownership field highlight the political nature of data, and illustrate the importance of politically aware interventions when creating open data standards, infrastructure, and ecosystems. State of Open Data, edited by Tim Davies, Stephen B. Walker, Mor Rubinstein, and Fernando Perini, is published by African Minds and International Development Research Centre, Canada.
