Open data is data that is made available by organisations, businesses and individuals for anyone to access, use and share.

Open data has to have a licence that says it is open data. Without a licence, the data can’t be reused.

The licence might also say:

● that people who use the data must credit whoever is publishing it (this is called attribution)

● that people who mix the data with other data have to also release the results as open data (this is

called share-alike)
