Introduction 介绍
Open source doesn’t just mean access to the source code. The distribution terms of open-source software must comply with the following criteria:
开源不仅仅意味着对源代码的访问。开源软件的分发条款必须符合以下标准：
1. Free Redistribution 免费再分发
The license shall not restrict any party from selling or giving away the software as a component of an aggregate software distribution containing programs from several different sources. The license shall not require a royalty or other fee for such sale. 该许可不得限制任何一方将软件作为包含来自多个不同来源的程序的聚合软件分发的组件进行销售或赠送。许可证不得要求为此类销售支付特许权使用费或其他费用。
2. Source Code 源代码
The program must include source code, and must allow distribution in source code as well as compiled form. Where some form of a product is not distributed with source code, there must be a well-publicized means of obtaining the source code for no more than a reasonable reproduction cost, preferably downloading via the Internet without charge. The source code must be the preferred form in which a programmer would modify the program. Deliberately obfuscated source code is not allowed. Intermediate forms such as the output of a preprocessor or translator are not allowed.
程序必须包含源代码，并且必须允许以源代码和编译形式分发。如果某种形式的产品没有与源代码一起分发，则必须有一种广为人知的手段，以不超过合理的复制成本获得源代码，最好是通过互联网免费下载。源代码必须是程序员修改程序的首选形式。不允许故意混淆源代码。不允许使用中间形式，例如预处理器或转换器的输出。
3. Derived Works 衍生作品
The license must allow modifications and derived works, and must allow them to be distributed under the same terms as the license of the original software.
许可证必须允许修改和衍生作品，并且必须允许它们以与原始软件许可证相同的条款分发。
4. Integrity of The Author’s Source Code 作者源代码的完整性
The license may restrict source-code from being distributed in modified form only if the license allows the distribution of “patch files” with the source code for the purpose of modifying the program at build time. The license must explicitly permit distribution of software built from modified source code. The license may require derived works to carry a different name or version number from the original software.
只有当许可证允许分发带有源代码的“补丁文件”以在构建时修改程序时，许可证才能限制源代码以修改后的形式分发。许可证必须明确允许分发由修改后的源代码构建的软件。许可证可能要求衍生作品使用与原始软件不同的名称或版本号。
5. No Discrimination Against Persons or Groups 不歧视个人或群体
The license must not discriminate against any person or group of persons.
许可证不得歧视任何个人或群体。
6. No Discrimination Against Fields of Endeavor 不歧视所从事的领域
The license must not restrict anyone from making use of the program in a specific field of endeavor. For example, it may not restrict the program from being used in a business, or from being used for genetic research.
许可证不得限制任何人在特定领域使用该程序。例如，它可能不会限制该程序用于企业或用于基因研究。
7. Distribution of License 许可证的分发
The rights attached to the program must apply to all to whom the program is redistributed without the need for execution of an additional license by those parties.
程序附带的权利必须适用于程序重新分发给的所有人，而无需这些方执行额外的许可。
8. License Must Not Be Specific to a Product 许可证不得特定于产品
The rights attached to the program must not depend on the program’s being part of a particular software distribution. If the program is extracted from that distribution and used or distributed within the terms of the program’s license, all parties to whom the program is redistributed should have the same rights as those that are granted in conjunction with the original software distribution.
附加到程序的权限不得依赖于程序是否是特定软件发行版的一部分。如果程序是从该发行版中提取的，并在该程序的许可条款内使用或分发，则重新分发该程序的所有各方都应拥有与原始软件发行版一起授予的相同权利。
9. License Must Not Restrict Other Software 许可不得限制其他软件
The license must not place restrictions on other software that is distributed along with the licensed software. For example, the license must not insist that all other programs distributed on the same medium must be open-source software.
许可证不得对与许可软件一起分发的其他软件施加限制。例如，许可证不得坚持在同一介质上分发的所有其他程序必须是开源软件。
10. License Must Be Technology-Neutral 许可证必须是技术中立的
No provision of the license may be predicated on any individual technology or style of interface.
许可证的任何规定均不得基于任何单独的技术或界面风格。
