The Lnu Publishing Policy, as decided by the Rektor, gives a recommendation to publish under the Creative Commons license ”BY-NC-SA”, which, in short, means that the creator must be named. The work can not be used in a commercial purpose and if the one using your work shares it further, he or she must do so under the same license.
As the creator you always own your own material. The Creative Commons licence is a way to easily and clearly let other know in what way you allow your work to be used.
The Publishing policy gives a recommendation and you are free to set any other form of Creative Commons license you wish, or you could opt to totally stop others from using your work. You set this in our portal, play.lnu.se, when you decide to publish your work outside Mymoodle.
