The report finds that 3 key groups or ‘layers’ were crucial to the successful introduction of open data. An influential and active civil society provided the ‘bottom up’ pressure for change through traditional advocacy and by setting up innovative websites demonstrating how open information could be used. Civil servants and state and federal administrators who saw open data as a way of improving efficiency provided the ‘middle layer’. Finally, high-level political leaders including Heads of States and Ministers provided the third layer.
