The code for the application developed & freely distributed along with the app. Hence programmers can download, modify, or correct code and make their contribution to a software package. The project application developed on co-operative open-source effort, so no company or institution has control over it. The development environment is global, and software protected by public licenses. No commercial company after modification can sell a product or copyright changes.
Significant software development projects include:
- KDE, GNOME, Netscape Navigator
- OpenOffice suite supported by Sun Open source project based on StarOffice suite.
- The Linux Foundation – the non-profit organization: The Linux distributed by the general public license GNU GPL provided by the Free Software Foundation, which retains copyright, i.e., free licensing software with its modifications.
