Weak Copyleft Open Source Licenses

Licenses that require changes to the licensed files to be shared under the same terms while allowing the code to be combined with software under other licenses. It covers the file-level and library-level copyleft licenses published by foundations and companies, such as the Eclipse, Common Development and Distribution, Lesser General Public and similar licenses. A license belongs here when the sharing obligation stops at the boundary of the licensed component. It excludes strong copyleft licenses, which extend to the whole combined work.
