We Love Open Source!
We love the freedom open source licenses gives us and the collaborative power of the community.
There are so many different licenses with numerous ramifications and definitions for use. So to keep things some what simple here are some basics from Open Source Initiative.
For a full listing of the individual Open Source Licenses and their full definitions please visit https://opensource.org/licenses for all current open source license definitions. Always remember if in doubt seek guidance from legal council on your individual use of any type of Open Source licenses. OSCGP is does not provide legal guidance and will not be held responsible for violation of license terms.
Free Redistribution – The license may not restrict any party from selling or giving away the software as a component or an aggregate software distribution containing several programs from several sources. The license may not require a royalty or other fee for such sale.
Source Code – 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 pre-processor or translator are not allowed.
Its about the source code
Derived Works – 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.
Integrity of The Author’s Source Code – 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.
No Discrimination Against Persons or Groups – The license must not discriminate against any person or group of persons.
No Discrimination Against Fields of Endeavor – 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.
Distribution of License – 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.
License Must Not Be Specific to a Product – 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.
License Must Not Contaminate Other Software – 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.
