Marking your work with a licence is useful if you want to give the user of the work more rights, or just remind the user of your rights. If you actively use social media for disseminating your work, this could be a wise thing to consider.
When reusing someone else's data, it is important to know which licensing conditions are in place to use the data. Investigate what you are allowed with the data, how the author wants to be cited and how you should refer to the data.
See also the libguide on copyright (in Danish).
Creative Commons (CC) provides six licences, each of which grants different rights to use the materials licenced under them. All of these licences offer more permissions than “all rights reserved”.
The CC licences allow four restrictions on using licensed material:
These restrictions can be combined into six standard licences: BY(-NC), BY-SA(-NC), and BY-ND(-NC). Creative Commons has also developed the special CC0 (“no rights reserved”) licence, where the copyright owner / licensee completely can renounce all its rights.
