The license, a text that describes how data can and can’t be used, is a must for open data. Without that clear statement of use, it’s impossible to tell if the information isn’t subject to copyright or other restrictions, so you’re using it at risk of litigation and legal challenges.

A good open data license has few restrictions – it allows as many people as possible to use the data with as few conditions as possible. The more conditions on your data, the harder it is to use it with other data.
