Licenses
The TYPO3 project, represented by the TYPO3 Association, uses different licenses for the distribution of software and documentation as well as for accepting contributions from individuals and corporations.
We have chosen to take advantage of these licenses because they support the vision and mission of the TYPO3 project ("Inspiring People to Share" and "Jointly Innovate Excellent Free Software Enabling People to Communicate"). Our Contributor License Agreements are basically a copy of the Apache CLA with a few cosmetic changes. In our search for licenses we have found their model to be the fairest and most effective for the contributors and the Association.
In all cases, contributors retain full rights to use their original contributions for any other purpose outside of TYPO3 while providing the TYPO3 Association and its projects the right to distribute and build upon their work within the TYPO3 project.
Licensing of Distributions
Our software distributions are licensed as follows:
- TYPO3 CMS 3.x - 4.x is licensed under the General Public License version 2 or higher.
- TYPO3 CMS 5.x and FLOW3 are licensed under the General Public License version 2.
Contributor License Agreements
Starting with TYPO3 version 5, the TYPO3 Association asks all contributors of ideas, code, or documentation to the TYPO3 projects (including FLOW3) to complete, sign, and submit an individual Contributor License Agreement (CLA). Signing such an agreement is not necessary (but recommended) for contributions to the version 4 branch of TYPO3.
The purpose of this agreement is to clearly define the terms under which intellectual property has been contributed to TYPO3 and thereby allow us to defend the project should there be a legal dispute regarding the software at some future time. We need to have a signed CLA on file before we can give you commit rights to one of the TYPO3 v5 projects.
For a corporation that has assigned employees to work on a TYPO3 project, a Corporate CLA (CCLA) is available for contributing intellectual property via the corporation, that may have been assigned as part of an employment agreement. Note that a Corporate CLA does not remove the need for every developer to sign their own CLA as an individual, to cover any of their contributions which are not owned by the corporation signing the CCLA.
