Open data is also a general movement for free and open data. The movement affects all industries, including culture, finance, and science. Some government platforms allow users to share and re-use data such as Data.gov in the US and Data.gov.uk in the UK.
The Open Knowledge Foundation defines open data as “any content, information or data that people are free to use, re-use and redistribute.” Data can thus be exchanged, shared, and modified. Criteria of “open” data are: availability, re-use, and global participation.
