Information About

Common Public License




The CPL is a Copyleft license, broadly similar to the GNU General Public License in its terms. The main difference is in a Patent clause designed to prevent unscrupulous contributors from contributing code which infringes on their Patents , and then attempting to charge royalties; in such a situation, the CPL requires the contributor to grant a royalty-free license to all recipients. This additional requirement renders the CPL incompatible with the GPL (in the opinion of Eben Moglen , and the GNU website), though it is possible that a future version of the GPL will adopt a similar, compatible clause.

Microsoft has released their Windows Installer XML (WiX) developer tool, Windows Template Library (WTL) and the FlexWiki engine under the CPL as Sourceforge projects.
