SIL开源字体许可（英语：SIL Open Font License，缩写OFL）是一种自由、开源的字体许可协议。由SIL国际制定，初版于2005年发布，如今已是诸多开源字体的首选授权条款，思源系列亦是其中之一。译文仅供参考，如有错误或建议也请赐教。此外，本译文并没有法律效力，请参见以下声明。
声明：本文为《SIL开源字体许可证》（简称《OFL》）的非官方中文翻译。其并非由SIL国际发表，也不是采用《OFL》的字体的法定发布条款。以《OFL》授权的发布版本只在使用英语原文条款时有效。
然而，我们承认这份非官方翻译可以帮助不熟悉英语的用户和设计师更好地理解《OFL》，并更加容易地在这一协作字体设计模式下使用和发布字体家族。如果可能的话，我们鼓励各位考虑以《OFL》发布创作的设计师以母语阅读常见问题集。

PREAMBLE
The goals of the Open Font License (OFL) are to stimulate worldwide
development of collaborative font projects, to support the font creation
efforts of academic and linguistic communities, and to provide a free and
open framework in which fonts may be shared and improved in partnership
with others.
The OFL allows the licensed fonts to be used, studied, modified and
redistributed freely as long as they are not sold by themselves. The
fonts, including any derivative works, can be bundled, embedded,
redistributed and/or sold with any software provided that any reserved
names are not used by derivative works. The fonts and derivatives,
however, cannot be released under any other type of license. The
requirement for fonts to remain under this license does not apply
to any document created using the fonts or their derivatives.
