Open Data supports and enhances Big Data’s availability and potential. The concept behind Open Data is that data should be freely available to everyone to use as they wish, without restrictions from copyrights, patents, or other mechanisms of control. It is already changing the way that governments address issues domestically and internationally. The European Commission defines Open Data as all the data and information produced, collected or purchased by government agencies – such as statistics and spatial data – as well as data resulting from projects financed by those government agencies. The concept highlights the initiatives by governments around the world to allow government Open Data for stakeholders in a way that enables researchers to obtain information that can be used safely. Such data should be provided in a machine-readable file format. Several national governments have created websites to distribute a portion of the data they collect. It is a concept for a collaborative project in municipal Government to create and organize Culture for Open Data or Open Government Data. A list of over 200 local, regional, and national Open Data catalogues is available on the catalog4. The World Bank, the United Nations and the European Union are leading this effort, and give access to large amount of data. ‎[33]
