What is Open Source Software (OSS)

1.

Open source software refers to software that is developed, tested, or improved through public collaboration and distributed with the idea that the must be shared with others, ensuring an open future collaboration. The collaborative experience of many developers, especially those in the academic environment, in developing various versions of the UNIX operating system, Richard Stallman's idea of Free Software Foundation, and the desire of users to freely choose among a number of products - all of these led to the Open Source movement and the approach to developing and distributing programs as open source software.

Open source software is software that any users could share, study, inspect, modify and enhance (What is open source?, 2019). Learn more in: Introduction to the Popular Open Source Statistical Software (OSSS)

3.

A strategic business-friendly “rebranding” of free software emphasising the practical benefits of the model of participatory software development and open code, and downplaying the original ideological and philosophical positions. Learn more in: Social Technologies and the Digital Commons

4.

Software that allows the user to see and alter the source code; closely related to free software. Learn more in: Open Source Software and the Corporate World

5.

Software for which the source code is open and available. Its licenses give users the freedom to access and use the source code for any purpose, to adapt and modify it, and to redistribute the original or the modified source code for further use, modification, and redistribution.

6.

Computer software available with its source code under an open source license to study, change and improve its design. The open source philosophy further defines a boundary on the usage, modification, and redistribution of open source software. Software licenses grant rights to users, which would otherwise be prohibited by copyright. These include rights on usage, modification, and redistribution. Several open source software licenses have qualified within the boundary of the Open Source Definition.

Software distributed under a license that allows users to copy, modify, and redistribute the software. Learn more in: An Innovative Desktop OSS Implementation in a School

8.

Software that meets the terms of the Open Source Definition ( www.opensource.org/docs/definition.php ). To be open source, the software must be distributed under a license that guarantees users the right to read, redistribute, modify, and use freely.

9.

A type of computer software in which source code is released under a license in which the copyright holder grants users the rights to study, change, and distribute the software to anyone and for any purpose ( Wikipedia, 2019c ).

10.

Open source software share the same principle of FS. According to Richard Stallman 'free software' and 'open source' describe the same category of software, more or less, but say different things about the software, and about values. He further said, “The Free Software Movement and Open Source Movement are two political parties in the same community”.

18.

Software whose source code is freely available on the Internet. Users can download the software and use it. Unlike proprietary software, users can see the software’s source code, modify it, and redistribute it under an open source license, acknowledging their specific contribution to the original.

19.

Software distributed both as source code and in compiled form. It cannot discriminate against any field of endeavor, group, or individual. It must come with a license that does not restrict derivative works and must not restrict any party from selling or giving away the code. Further, rights to use the code cannot be tied to a specific program and cannot restrict any other software or program to be of a certain origin or type (Open Source, 2005 AU26: The in-text citation "Open Source, 2005" is not in the reference list. Please correct the citation, add the reference to the list, or delete the citation. ). Learn more in: Open Source E-Learning Systems: Evaluation of Features and Functionality

20.

It’s a computer software for which the source code and certain other rights normally reserved for copyright holders are provided under a software license that is in the public domain. This permits users to use, change and improve the software and to redistribute it in modified or unmodified forms.
