Is it really free?



“Open source is a set of principles andpractices on how to write software.” –Wikipedia.

Based on Perens' principles



1. Free Redistribution• The software can be freely given away or sold.• This was intended to expand sharing and use of the software on a legal basis.

1. Source Code• The source code must either be included or freely obtainable.

• Without source code, making changes or modifications can be impossible.

1. Derived Works• Redistribution of modifications must be allowed.• To allow legal sharing and to permit new features or repairs.

1. Integrity of The Author's Source Code• licenses may require that modifications are redistributed only as patches.

1. No Discrimination Against Persons or Groups• no one can be locked out.



6. No Discrimination Against Fields of Endeavor• commercial users cannot be excluded.

7. 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 anadditional license by those parties.

6. License Must Not Be Specific to a Product• The program cannot be licensed only as part of a larger distribution.

6. License Must Not Restrict Other Software

• The license cannot insist that any other software it is distributed withmust also be open source.

6. License Must Be Technology-Neutral• No click-wrap licenses or other medium-specific ways of accepting

the license must be required.



The word "free" in our name does not referto price; it refers to freedom.

•First, the freedom to copy a program andredistribute it to your neighbors, so that theycan use it as well as you.

•Second, the freedom to change a program, sothat you can control it instead of it controllingyou; for this, the source code must be madeavailable to you.



Freedom 0: The freedom to run the program forany purpose.

Freedom 1: The freedom to study and modifythe program.

Freedom 2: The freedom to copy the program soyou can help your neighbor.

Freedom 3: The freedom to improve theprogram, and release your improvements to thepublic, so that the whole community benefits.
