The ÖLAB Software License is based on the Peer Production License which in turn has been derived from the Creative Commons ‘Attribution-NonCommercial-ShareAlike’ license. The license only applies to original code and content created by/for Öppenlab projects and does not apply to any 3rd party libraries/dependencies. These types of license are sometimes called Copy-far-left and are different from the Open Source licenses in that they explicitly do not allow commercial use. They're also sometimes referred to as 'anti-capitalist' licenses.
