The World Bank defines open data as data and/or valuable information that is free and easily accessible to anyone, without limitations or restrictions. Data or content is open if anyone is free to use, re-use or redistribute it, subject at most to measures that preserve provenance and openness.Open data brings wide-ranging benefits to governments and many different groups, organisations and individuals. It keeps duty bearers or governments alert and responsive to society and responsible for their actions. Similarly, it empowers rights holders or citizens to know what their government is doing and to hold them to account. It strengthens citizens, including marginalised groups, to be directly informed and involved in the decision-making processes of governance in both public and political spaces.
