Dealing with network software projects many based on imaging I have a preferred license model: that favors Apache License version 2.0 that allows all uses for the code, and this can incorporate other licenses say for libraries etc.

Thanks over many discussion for this policy for contributing as a modified version of the CCP_PETMR / CCP_i communities.

To contribute code to this project, (“the Software”) this is under the terms of the Apache License version 2.0 (AL2). The Software provided is described as follows: {add details here}.

Any other software unless I indicate otherwise at the time of provision, such additional software shall be deemed incorporated into the definition of “the Software” under this Agreement and licensed to the owners under the same terms as this agreement. Such contribution could for instance take the form of a submission of a pull-request or a git commit.

The ownership of the copyright in the Software licensed will remain with us the contributor and we request that the names of the authors as copyright owner, are acknowledged on any copy of the Software that you may release in original or modified form.

Furthermore, as stated by the AL2 terms and without intending to affect those terms, the Software is provided without any warranty as to its quality or fitness for any general or particular purpose.

We confirm that the Software was entirely created by the authors named and that the licence granted under this letter will be valid and binding upon us.
