Contributor License Agreement

Currently, the main development of pySPACE happens at the German Research Center for Artificial Intelligence (DFKI GmbH), Robotics Innovation Center, Bremen (DFKI RIC). To avoid legal issues with intellectual property rights, and to keep the possibility to change the license in future versions, we followed the concept by the Webyog company which developed MySQL.

If you want to contribute to pySPACE, we kindly ask you to fill out this pdf file and send it to us as explained in the pdf file.
