Licenses

Licenses are a way to deal with copyright issues: Authors can grant users rights to use their work whilst retaining copyright. A license thus essentially provides other users the legal permission to perform certain acts that are otherwise restricted by copyright. It does not transfer any exclusive rights to the licensee; the rights stay with the licensor, the creator of the work.

Open Data Commons licenses

Open Data Commons Licenses are very similar to the Creative Commons Licenses but are specific to data (and can only be used to license data).


How to apply a license to your work

  1. First, determine the copyright. Only as the copyright owner can you license your work freely.
  2. Determine if you are using other works that are also licensed and restrict you in your choice of licenses (e.g. -SA- additions of CC licenses).
  3. Choose a CC license, e.g. with the License Chooser. If you want to share your data openly, choose an “open license”, e.g. CC-BY or CC-BY-SA.
  4. Write a short text on your work (e.g. on the title page or last slide). Make sure to include the name of the license and the link to the license text. For example:

    This work is licensed under a CC-BY 4.0 International License (https://creativecommons.org/licenses/by/4.0/).

Software

Software can also be protected by copyright. This covers both the executable and the source code, as well as the graphic interface. However, functionalities and ideas are not protected. For the licensing of software there are a lot of different licenses (e.g. MIT, GPL). The website “Choose a License” helps you to decide on a software license.
