Definition Of Open Source Software

• Free Redistribution: No restrictions are placed on parties from selling of giving away the software.
• Source Code Availability: The software must include source code and must also allow for binary distributions when there is a well-publicized means of obtaining the source code.
• Derived Works: Modifications and derived works must be allowed, and must be distributed under the same terms as the license of the original software.
• Integrity of the Authors Source Code: The distribution of modified source code must be allowed although restrictions to ensure the possibility to distinguish the original source code from the derived works are tolerated. For example, the possibility of using different software names.
• 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 given by the license must not be different for the original distribution and any other one even when it takes place in a totally different context.
• 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.
