Opensource
Open Source refers to programs that make their source code available to the general public. The code is usually created and improved upon collaboratively.
According to the Open Source Initiative , open-source software must comply with the following criteria:
-
Free Redistribution
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. - Source Code
The program must include source code, and must allow distribution in source code as well as compiled form. - 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. - Distribution of License
The rights attached to the program must not depend on the program's being part of a particular software distribution. - License Must Not Be Specific to a Product
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.
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 Restrict Other Software
The license must not place restrictions on other software that is distributed along with the licensed software. - License Must Be Technology-Neutral
No provision of the license may be predicated on any individual technology or style of interface.
