Selecting a Data License Which License Should I

Selecting a Data License Which License Should I Apply to My Data?

Which license should I select? It is always a good idea to select a license which is commonly used. This helps to ensure the maximum re-usability of your work. If your discipline usually uses a specific license, then you should strongly consider it as well. Public Domain ‘licenses’ are actually waivers that remove the copyright and related rights to your content. They place your data into the open for anyone to use as they wish, with no restrictions, and no attribution requirement. There are three main providers for data licenses: Creative Commons, Open Data Commons, and GNU. They each have specific strengths, and are intended for different data formats. 2

Creative Commons licenses are the best choice for most all of your content. All CC licenses require attribution. http: //creativecommons. org/licenses/ • CC BY: Allows others to distribute, remix, tweak, and build on your work, even commercially. • CC BY-SA: Allows others to distribute, remix, tweak, and build on your work, even commercially, and they must license their new creations under the same terms. • CC BY-ND: Allows for redistribution, commercial or noncommercial use, but they can’t change the work. 3

Creative Commons CC BY-NC: Allows others to distribute, remix, tweak, and build on your work, even non-commercially. Their new works must be noncommercial, but they can license them under different terms. CC BY-NC-SA: Allows others to distribute, remix, tweak, and build on your work, non-commercially, and they must license their new creations under the same terms. CC BY-NC-ND: Others can only download and share your works. The Creative Commons Zero (CC 0) is a public domain dedication which can be used if you wish to permanently surrender your copyright and related rights to your work, with no attribution. It can be used for all types of content. http: //creativecommons. org/about/cc 0 4

CL): You waive all rights to the individual contents of a database licensed under the ODb. L.
