The projects developed by the Open Source Research Group at the University of Erlangen-Nürnberg are intended to be
Open Source and Sustainable.
However, there are threats to these goals:
- A contributor withdraws permission post facto.
- The project needs to change license at later point.
- A patent infringement lawsuit is filed against project users.
Our answer to these threats is the use of a Contributor License Agreement which
- ensures the use of an Open Source License,
- allows for Later License Change and
- provides a Full Patent Grant.
If you want to make a contribution please download the Contributor Agreement used by the OSR Group, complete and sign the form, then scan and email a pdf file to firstname.lastname@example.org. You may also send the signed form by facsimile to the OSR Group at +49 9131 85 28809.
Contributor Agreement FAQ
The answers in the FAQ section are not authorative. Only the wording of our Contributor Agreement applies.
- F: Do I loose any rights?
A: No, you’re granting us some of your rights, but that doesn’t take away these rights from you.
- F: Is this common practice?
A: Yes, practically all foundations (Apache, Eclipse, FSF, …) but also companies involved with Open Source (IBM, Red Hat, MySQL, …) require Contributor Agreements.
