The term “open source” refers to something that can be modified and shared because its design is publicly accessible.
While it originated in the context of computer software development, today the term “open source” designates a set of values—what we call the open source way. Open source projects, products, or initiatives are those that embrace and celebrate open exchange, collaborative participation, rapid prototyping, transparency, meritocracy, and community development.
What is open source software
Open source software is software whose source code is available for modification or enhancement by anyone.
The software being distributed must be redistributed to anyone else without any restriction.
The source code must be made available (so that the receiving party will be able to improve or modify it).
The license can require improved versions of the software to carry a different name or version from the original software.
