Open Licenses and Creative Commons

Myth – Open means it’s free without restriction. Reality   Not necessarily, open means available for use or re-use that may include released under an open licence such as Creative Commons.  

What is an open license?

A traditional license is a document that specifies what can and cannot be done with a copyright work (ie, images, video, sound, text, or multimedia).  Licenses usage rights and also usage restrictions. An open license grants rights to access, re-use and redistribute a work with few or no restrictions.

For example, an image on a website made available under an open license would be free for anyone to:

  • print out and share,
  • publish on another website or in print,
  • make alterations or additions,
  • and do many other things …

Openly licensed works are free to be shared, improved and built upon!

There are many forms of open licenses, for a list of the most common open licenses, see the Open Knowledge Licenses page.
