To submit code, patches, and proposals to Zend Framework, contributors must agree to the New BSD License and also submit a signed Contributor License Agreement (CLA). Companies may opt to submit a Corporate CLA if one or more of their employees will be contributing to Zend Framework as part of their work.
We welcome reports of issues or feature requests in our issue tracker, and we welcome participation and questions on the mailing lists. You can also publish articles and code on DevZone or on your own blog or website, but anything that constitutes intellectual property cannot be included in Zend Framework unless it is contributed under the terms of the CLA.
Not Required for ZF2 Development
Please note that the CLA requirement is only for development on the 1.X series; it is not required for development on the 2.x series and above.
ALWAYS send an email to firstname.lastname@example.org:
PLEASE PRINT CLEARLY USING LARGE LETTERS
CLA may be submitted using any method below:
We collect faxes periodically. Usually we receive and process faxes in about 5 business days.
When we process the faxes, we reply to the email address listed on the CLA. If you have not received confirmation of receipt within 7 business days, then please check the fax phone number, email email@example.com directly, or resend by fax, depending on the circumstances.
By signing a CLA, the person contributing source code provides a license to Zend to use the source code he submitted in Zend Framework. By doing so, the contributor does not give up his own rights or copyright to his own code, but provides us with a license. In addition, the purpose of the CLA is to clearly define the terms under which intellectual property has been contributed to Zend Framework and to make sure that to the best of the contributor's knowledge he is entitled to make such contribution and is not violating anyone else's intellectual property.
Actually, the CLA doesn't just protect large companies; it protects all users including small and medium businesses and individuals. By having a CLA in place, we mitigate the risk of companies like SCO claiming intellectual property infringement and coming after users of the Zend Framework, whether individuals or companies, for licensing fees. This is especially important for companies who are planning to base their business or products on Zend Framework.
As mentioned, by requiring contributors to sign a CLA, we mitigate the risk of accepting contributions which infringe third parties' intellectual property rights.
No. By signing the CLA you do grant Zend the right to use your contribution, but as stated in the CLA, "You reserve all right, title, and interest in and to Your Contributions."
A CLA for a contributor under the age of 18 should be signed by both the contributor and the contributor's legal guardian.
