Everything about The Eclipse Public License totally explained
The
Eclipse Public License (
EPL) is an
open source software license used by the
Eclipse Foundation for
its software. It replaces the
Common Public License (CPL) and removes certain terms relating to
patent litigation.
The Eclipse Public License is designed to be a business friendly free software license, and features weaker
copyleft provisions than contemporary licenses such as the
GNU General Public License (GPL). The receiver of EPL-licensed programs can use, modify, copy and distribute the work and modified versions, in some cases being obligated to release their own changes.
The EPL is approved by the
Open Source Initiative (OSI) and the
Free Software Foundation (FSF)
The EPL, in addition, contains a
patent retaliation clause, which is incompatible with the GPL for the same reasons. But GPL version 3 also has a patent retaliation clause in section 10.
Derivative works
The EPL allows the developers of changes and additions of EPL-licensed code to make their own license under any type of license they choose for the changes and additions separately. However, the EPL-licensed part of their derivative software product should be licensed under EPL license, but the developers can have private right about the portions of changes and additions.
In EPL, as with every
free software licence, the contributor can charge money for programs which the contributor changed and added to the program. Also, there are no restrictions on providing source code. The contributor can make, use, sell, offer to sell, import and transfer the contribution. but there are some differences between the two licenses:
- The Eclipse Foundation replaces IBM as the Agreement Steward in the EPL
- The EPL patent clause is revised by deleting the sentence from section 7 of the CPL
