Open data is the idea that certain data should be freely available for everyone to use and republish as they wish. The philosophy behind open data has been long established, but the term itself is relatively new and it is gaining popularity.
An increasing number of platforms where people can openly share information have been developing, such as GitHub, where you can share codes and other ideas for open source programming, and WikiHouse, an open source construction set which lets you build your own home from online templates.
Here are a few examples of how open data is being used by local government.
