In most jurisdictions there are intellectual property rights in data that prevent third-parties from using, reusing and redistributing data without explicit permission. Even in places where the existence of rights is uncertain, it is important to apply a license simply for the sake of clarity. So, for “open” data, it is advisable to use a license for dedication to the public domain or share-alike (plus attribution), through Creative Commons or Open Data Commons.
The following licenses conform with the principles set forth in the Open Definition.
