Open Source -Open Source-Just like free software, it is software that offers the user the freedom to use, understand, modify, and distribute the software. This community movement was born in a strategy session held in California on February 3, 1998. The Open Source definition is derived from the revised Debian1 Free Software Guidelines. Therefore, we can say that Free Software and Open Source are almost the same. While open source focuses on improving the collaborative software development methodology, Free Software prioritizes the technology of its time and its philosophy as a necessity.

The distribution conditions of the software must comply with the following criteria:

1. Free Redistribution

An open source software license does not require copyright or other fees for the sale or distribution of software as a component of a mass distribution of software that includes programs from several different sources.

2. Source Code Open

The software should be distributed as open source, if it is distributed in a compiled form, it should include the source code or allow easy and free access to the source code. This source code should be in a form that the programmer can understand and change, and its comprehensibility should not be consciously hindered.

3. Derived Works

The license must allow modifications and derivative works and must allow them to be distributed under the same conditions as the license for the original software.

4. Integrity of the Author's Source Code

The license may restrict distribution of source code in modified form, but must also explicitly permit distribution of software created from modified source code.

5. No Discrimination Against Individuals or Groups

Any person or person in the license of software licensed as open source grubIt is not possible to discriminate against.

6. No Discrimination Based on the Field of Study.

The use of the software for any purpose cannot be prevented.

7. Distribution of License

Rights added to the program must apply to anyone to whom the program is redistributed without the need for an additional license to be applied by those parties.

8. The License must not be Specific to a Product.

Rights added to the software should not be dependent on the program being part of a particular software distribution.

9. The License Must Not Restrict Other Software.

The license should not impose restrictions on other software distributed with the licensed software. For example, the license should not insist that all other programs distributed in the same environment be open source software.

10. The License must be Technology Independent.

License clauses cannot impose a technology or interface.

Why Free Software?

Of course, the development of science can reach its absolute speed with the sharing of knowledge. The use of symbols -writing- in communication ensured the transfer of knowledge to future generations and the accumulation of knowledge carried us to today. Sharing information for the benefit of humanity without closing it -without monopolizing it- will carry us to the future faster. Sharing information openly is possible with free/open source software, free/open document, free technology licenses. Free and open source software licenses, unlike closed source -proprietary software licenses, protect the rights of users and software with these licenses is always open to co-production -development-.
