This study report examines strategies that aim to foster open access to scientific data—such as the types of incentives given at the researcher and institutional levels and the level of compliance by researchers and funded organizations—and also examines how, and whether, these policies are monitored and enforced. The infrastructures developed to store and share OA scientific data are also examined. The analysis is supported by findings from the literature on the global progression of OA scientific data since 2000—including its growth as a segment of scholarly publishing—as well as some broader themes and debates that have emerged from the movement.
