MariaDB Contributor Agreement FAQs

What is the intention of the MCA?

  1. The original copyright holder and the MariaDB Foundation both get (shared) copyright for the code.
  2. Both parties can use their copy independently of each other for any purpose (as if each copy was completely separate and unique).

What if I don’t want to submit code to you under the MCA?

If you don’t like the MCA for code that you want to contribute to MariaDB, the other option is to submit your code under the BSD-new license.

We need shared copyright for the following reasons:

  1. to defend the copyright or GPL if someone breaks it (this is the same reason the Free Software Foundation also requires copyright assignment for its code)
  2. to be able to donate code to MySQL (for example to fix security bugs or new features)
  3. to allow people who have a non-free license to the MySQL code to also use MariaDB (the MCA/BSD allows us to give those companies the rights to all changes between MySQL and MariaDB so they can use MariaDB instead of MYSQL)

What will the MariaDB Foundation do with the code I contribute?

The MariaDB Foundation agrees that when it dual licenses code, it will not restrict the way the third party licensee uses the licensed copy of the code nor restrict how they use their own code.

Where did the MCA come from?

The MCA is based on Sun’s Contributor Agreement. We think it is one of the best contributor agreements around!

What’s the difference between Sun’s SCA and the MCA?

Sun’s SCA was unclear in a couple of points which we have fixed in the MCA:

  • The patent grant has been made clear that it only affects the donated code, not any other code.
  • We added a clarification how code is donated; “Each submission must explicitly be marked that it’s donated under the MCA”
  • We have made a promise in this FAQ how the MariaDB Foundation will Dual-license code. See Monty’s blog post “Thoughts about Dual-licensing Open Source software” for a discussion about this.

What happened to the Monty Program Contributor Agreement?

With the establishment of the MariaDB Foundation, Monty Program Ab transferred all existing signed contributor agreements to the Foundation.
