Community-led development "The Apache Way"
This policy provides licensing guidance to Apache Software Foundation projects. It identifies the acceptable licenses for inclusion of third-party Open Source components in Apache Software Foundation products.
If they have a licensing question, projects are asked to submit questions to the Legal Affairs Committee JIRA space.
The following criteria serve as guidelines for the categories on this page.
a. (reviewed: 2019-02-16)
At a high level this policy separates licenses into three categories.
For the purposes of being included in an Apache Software Foundation product, the following licenses are considered to be similar in terms to the Apache License 2.0:
Many of these licenses have specific attribution terms that need to be adhered to, often by adding them to the NOTICE file能让你湿到不行的小说. Ensure you are doing this when including these works.
Works in the public domain (or covered by a license treated similarly) may be included within Apache products. Attribution is required (in a similar fashion to the Category A list.
A work should be treated as being in the public domain when one of the following applies:
Licenses that should be treated as similar to public domain:
Note that能让你湿到不行的小说 whether a work falls in the public domain may be a subject. Determining whether the copyright in a work has expired may be non-trivial and may vary between jurisdictions. Raise the topic on legal-discuss@ or via a JIRA issue if you have doubt over whether a work falls in the public domain.
For the purposes of being included in an Apache Software Foundation product, licenses and/or projects described in this section may be included IF能让你湿到不行的小说 specified conditions are met.
In all Category B cases our users should not be surprised at their inclusion in our products. By attaching an appropriate and prominent label to the distribution users are less likely to be unaware of restrictions significantly different from those of the Apache License. An appropriate and prominent label is a label the user will read while learning about the distribution - for example in a README, and it should identify the third-party product, its licensing, and a url to the its homepage. Please also ensure to comply with any attribution/notice requirements in the specific license in question.
Unless otherwise specified, all Category B licensed works should be included in binary-only form in Apache Software Foundation convenience binaries (and not source code).
能让你湿到不行的小说Each license in this section requires some degree of reciprocity. This may mean that additional action is warranted in order to minimize the chance that a user of an Apache product will create a derivative work of a differently-licensed portion of an Apache product without being aware of the applicable requirements.
Software under the following licenses may be included in binary form within an Apache product if the inclusion is appropriately labeled (see above):
By including only the object/binary form, there is less exposed surface area of the third-party work from which a work might be derived; this addresses the second guiding principle of this policy.
For small amounts of source that is directly consumed by the ASF product at runtime in source form, and for which that source is unmodified and unlikely to be changed anyway (say, by virtue of being specified by a standard), inclusion of appropriately labeled source is also permitted. An example of this is the web-facesconfig_1_0.dtd, whose inclusion is mandated by the JSR 127: JavaServer Faces specification.
Works under the licenses (2.5, 3.0, and 4.0) contain terms related to "Effective Technological Measures", which may come as a surprise to users. Thus their inclusion shall be appropriately labelled and only in binary form.
Unmodified media under the , and licenses may be included in Apache products, subject to the licenses attribution clauses which may require LICENSE/NOTICE/README changes. For any other type of CC-SA licensed work, please contact the Legal PMC.
能让你湿到不行的小说Note that media is intended to mean binary visual/video/audio elements used in our documentation. It is not intended to mean inclusion inside our source code.
能让你湿到不行的小说No, not without contacting the original author and getting permission from them to use the code in an Apache project under the Apache License 2.0.
Doug Lea's concurrent library is public domain, but contains some Sun files which are not public domain. This may be included in ASF products much like the 'weak copyleft' list above. "It may be included in binary form within an Apache product if the inclusion is appropriately labeled". If using the source, remove the files Sun licensed to Doug and treat as Category A (or get the files from Harmony).
Insertion of OSGi metadata into 'Category B' licensed jars is permitted providing that a note that this has occurred is included in the prominent labeling for the jar.
Cobertura reports may be included in ASF distributions.
There are licenses that give broad rights for redistribution of unmodified copies. Such licenses are not open source, but they do satisfy the second and third guiding principles above.
能让你湿到不行的小说Apache projects must not include material under such licenses in version control or in released source packages. It is however acceptable for a build process to automatically download such non-software materials like fonts and standardized data and include them in the resulting binaries. Such use makes it clear that these dependencies are not a part of the open source code of the project.
Material under the following licenses may be used as described above:
能让你湿到不行的小说Many languages have developed an ecosystem of associated tools that aid in the building of artifacts for distribution. While such tools may not always be made available under an otherwise compatible license, specific tools have been OK'ed for inclusion in Apache distributions when used for that specific purpose.
Note that the tool must not affect the licensing of the project source code. It is also expected that our use of the tooling to build our source code is its typical use.
To date, the following tools have been approved for such usage:
Developing Perl bindings which link compiled C code to create dynamically loaded XS modules requires including header files licensed under the Perl license (http://dev.perl.org/licenses/ - GPL-any/Artistic1, with exceptions).
You may include these header files - XSUB.h, perl.h and EXTERN.h (see: LEGAL-79).
As long as the generated comments are removed from the Doxygen-generated files, these files may be used.
A project written primarily and obviously in Ruby can have a dependency either on Matz's Ruby Interpreter (MRI),
or on any Gem which is licensed under the .
能让你湿到不行的小说 Of course Gems written under other licenses (such as MIT) may also be OK, depending on the license.
Also note that the Ruby license is listed on the 'Category B' Weak Copyleft list above for binary usage (for example JRuby).
The following licenses may NOT be included within Apache products:
能让你湿到不行的小说Details of 'other concerns':
Apache projects may not distribute Category X licensed components, be it in source or binary form; and be it in ASF source code or convenience binaries. As with the previous question on platforms, the component can be relied on if the component's license terms do not affect the Apache product's licensing. For example, using a GPL'ed tool during the build is OK, however including GPL'ed source code is not.
能让你湿到不行的小说Apache projects can rely on components under prohibited licenses if the component is only needed for optional features. When doing so, a project shall provide the user with instructions on how to obtain and install the non-included work. Optional means that the component is not required for standard use of the product or for the product to achieve a desirable level of quality. The question to ask yourself in this situation is:
It does not matter, unless the terms for that platform affect the Apache product's licensing. For example, creating a product that runs on Windows or Java, uses a web service such as Google Services or Yahoo Search, or is a plugin for a product such as JBoss or JIRA is fine, whereas creating a Linux kernel module is not fine because the Apache product itself would have to be licensed under something other than the Apache License, version 2.0.
Note that this does not mean the platform code itself can be redistributed. That of course will depend on the licensing of said code. Also, if you have any doubts as to whether the licensing of the platform would affect the Apache code, we recommend that you check the legal-discuss@ archives to see if it has come up before, and if not email legal-discuss@ to find out.
IP clearance能让你湿到不行的小说 is used to import code bases from outside Apache for future development here.
When including that work's licensing, state which license is being used and include only the license that you have chosen. Prefer Category A to Category B to Category X. You don't need to modify the work itself if, for example, it mentions the various licensing options in the source headers.
When a release contains third party works, the licenses covering those works may ask that consumers are informed in certain specific fashions. These third party notices能让你湿到不行的小说 vary from license to license. Apache releases should contain a copy of each license, usually contained in the LICENSE document. For many licenses this is a sufficient notice. For some licenses some additional notice is required. In many cases, this will be included within the dependent artifact.
A required third-party notice is any third party notice which isn't covered by the above cases.
See Bundling Other ASF Products for a note on required notices when a release contains another Apache product.
