See the open source definition
1) Generally, software for which the original program instructions, the source code, is made available so that users can access, modify, and redistribute it. The Linux operating system is an example of open source software. 2) Software that meets each of nine requirements listed by the non-profit Open Source Initiative in its Open Source Definition.
Software available free of charge as an alternative to conventional commercial models. Open source software can be used and disseminated at will, and the source code is open and can be changed as required. The only condition is that the user make such changes known and pass this information on to others. Open source software is the shared intellectual property of all developers and users and, thanks to the collaboration, achieves a higher level of quality than software produced using conventional means. The best known example of open source software is the Linux operating system.
