Fork (software development)
In software engineering, a project fork happens when developers take a copy of source code from one software package and start independent development on it, creating a distinct and separate piece of software.
Free and open-source software may be legally forked without prior approval of those currently developing, managing, or distributing the software per both The Free Software Definition and The Open Source Definition:
Open Source Initiative
The Open Source Initiative (OSI) is the steward of the Open Source Definition, the set of rules that define open source software.
Free and open-source software
Free and open-source software (FOSS) is software that is both free software and open-source software where anyone is freely licensed to use, copy, study, and change the software in any way, and the source code is openly shared so that people are encouraged to voluntarily improve the design of the software.
Open-source software development
Open-source software development (OSSD) is the process by which open-source software, or similar software whose source code is publicly available, is developed by an open-source software project.
Free software
Computer software distributed under terms that allow users to run the software for any purpose as well as to study, change, and distribute it and any adapted versions.
Although both definitions refer to almost equivalent corpora of programs, the Free Software Foundation recommends using the term "free software" rather than "open-source software" (a younger vision coined in 1998), because the goals and messaging are quite dissimilar.
Open-source license
Type of license for computer software and other products that allows the source code, blueprint or design to be used, modified and/or shared under defined terms and conditions.
One popular set of open-source software licenses are those approved by the Open Source Initiative (OSI) based on their Open Source Definition (OSD).
Netscape
American independent computer services company with headquarters in Mountain View, California and then Dulles, Virginia.
In January 1998, Netscape started the open source Mozilla project.
Open collaboration
Any "system of innovation or production that relies on goal-oriented yet loosely coordinated participants who interact to create a product of economic value, which is made available to contributors and noncontributors alike."
It is prominently observed in open source software, but can also be found in many other instances, such as in Internet forums, mailing lists and online communities.
