This is the repository for the Free and Open Source licenses maintained by Yzena.
There are four licenses, in order from least to most restrictive:
- Yzena Open License
- Yzena Copyleft License
- Yzena Access License
- Yzena Viral License
In general, the more restrictive licenses only add restrictions. Thus, every license could be considered to be a subset of the one that follows it.
Yzena Open License
The YOL is a permissive license with protections against patent litigation and trademark infringement. It also requires giving credit.
Yzena Copyleft License
The YCL is the most permissive copyleft Yzena license. It contains everything in the YOL.
Because it is copyleft, it also requires that changes to software under this license remain under the YCL or any of the more strict Yzena licenses.
This license also has an anti-tivoization clause.
This is not a viral copyleft license, however; only the changes to the software under this license must be under one of the Yzena copyleft licenses.
Yzena Access License
The YAL is the Yzena copyleft license that is intended to close the SaaS loophole. It does this by changing the GPL definition of distribution from "making available to the public" to "making available for public use."
It is still copyleft, but it only allows relicensing under itself and the YVL.
It also contains everything in the YCL as well.
Yzena Viral License
This is the most restrictive Yzena license and the first viral copyleft Yzena license. It contains everything in the YAL, but changes the relicensing provision to require that all software combined with the licensed software be put under the YVL.
