SIL Open Font License

from Wikipedia, the free encyclopedia

The SIL Open Font License ( OFL ) is a free license issued by the Summer Institute of Linguistics (now SIL International ) for the licensing of fonts , which has been recognized as free by the Free Software Foundation - so-called open source fonts .

Fonts licensed under the OFL include: B. EB Garamond , Gentium , Linux Libertine , Charis SIL or Doulos SIL.


Similar to the GPL , this license allows software licensed through it (in this case: digital fonts) to be freely copied, used, modified and distributed (also as part of another software system). However, the license does address a few cases that affect fonts. A derivative work may not be given the same name (without the consent of the author). Furthermore, the licensed font may not be sold alone. Finally, it should be noted that this license does not explicitly affect documents that use a licensed font. Only the font itself is affected by it.
