Choosing a license for your own work

When choosing a license:

  • Remember the license may not be revoked. Once you apply a CC license to your material, anyone who receives it may rely on that license for as long as the material is protected by copyright and similar rights, even if you later stop distributing it.

  • Make sure the material is appropriate for CC licensing. Specify precisely what it is you are licensing. Any given work has multiple elements; e.g., text, images, music. Make sure to clearly mark or indicate in a notice which of those are covered by the license.

Make sure the license grants permission for what you want to do.

we recommend to use CC BY for your own documents. For the Open Online Courses, TU Delft uses CC BY-NC-SA 4.0 International license.
