The Open Source Definition is used by the Open Source Initiative to determine whether or not a software license can be considered open source.The definition was based on the Debian Free Software Guidelines, written and adapted primarily by Bruce Perens.

Open Source Software is defined by its attached license guaranteeing anybody rights to freely use, modify, and redistribute the software.

Open Source is a certification mark owned by the Open Source Initiative. Developers of software that is intended to be freely shared and possibly improved and redistributed by others can use the Open Source trademark if their distribution terms conform to the OSI’s Open Source Definition.

To summarize, the Definition model of distribution terms require that:

Free Redistribution

• No restrictions are placed on parties from selling of giving away the software.

Source Code Availability

• The software must include source code and must also allow for binary distributions when there is a well-publicized means of obtaining the source code. continue

Bruce Perens is a computer programmer and advocate in the open source community. He created the Open Source Definition and published the first formal announcement and manifesto of open source. He co-founded the Open Source Initiative with Eric S. Raymond.

In 2005, Perens represented Open Source at the United Nations World Summit on the Information Society, at the invitation of the United Nations Development Program. He has appeared before national legislatures and is often quoted in the press, advocating for open source and the reform of national and international technology policy.

Open Source Software (OSS) is computer software for which the source code and certain other rights normally reserved for copyright holders are provided under General Public License (GPL) that meets the Open Source Definition or that is in the public domain.

Software whose source code is published and made available to the public, enabling anyone to copy, modify and redistribute the source code without paying royalties or fees. Open source code evolves through community cooperation. These communities are composed of individual programmers as well as very large companies.
