Introduction Internet Growth during the past few years has been
profoundly affected the way software is licensed and distributed. One of the most important changes that has occurred during this period is emergence of so-called open source licensing.
Open Source refers to a software program or set of software technologies which are widely available by an individual or group in form of Code form for use Modification Redistribution
Under a license agreement having few restrictions

History Formation of the Software Foundation (FSF) in 1983 FSF released a series of programs in source code from
under “GNU” GNU also set stage for even more free software
development projects in 1990s The license agreement that accompanied the GNU
software – known as the General Public License (“GPL) of “copyleft” license
In 1998, a group associated with free software introduced the term “open source”

Open Source Software in Today’s World No restrictions preventing others from selling and giving
away the software Source code must included in the distribution No restriction preventing people from modifying the
source code No Restriction regarding how people can use the
software Same rights apply to everyone receiving redistributions
of the software (copyleft)

Benefits of Open-Source Software
Gives opportunity to improve Rapid evolution of open-source software as a
result new versions of programs appears more frequently
Eliminates tension between obeying copyright law and helping others
Open-Source programs are property of the entire user community.

Continue….
Shifts focus from manufacturing to service which can result customers getting better support for their software.
Access to Source Code Cost

Example of Open-Source Software
Apache BIND PERL, Python, Ruby FireFox GNU compilers from C, C++, Object-C, Fortran,
Java, Ada Open Source Frameworks Sturts, Spring,
Hibernate, Apache POI, FOP, iText

Success Story: GNU Project and Linux
GNU and Linux are important success stories Richard Stallman begun the GNU Project in 1984 Goal: To Develop a complete Unix-like operating
system consisting entirely of open-source software. Most components developed in late 1980s
Linux In 1991 Linus Torvalds wrote Unix-like kernel Torvalds combined kernel with GNU components to
make an operating system called linux

Influence of Open-Source Software
As a reliable open-source alternative to Unix, Linux is putting pressure on companies selling proprietary versions of Unix.
Linux is also putting pressure on Microsoft and Apple, which sell proprietary operating systems for desktop systems.

Legal & Other Risk Associated
Potential liability for intellectual property infringement.
Open Source create opportunities for contributors therefore, it introduce infringing code and makes it almost impossible to audit the entire code base
Typical license form doesn’t include any intellectual property representation, warranties or indemnities in favor of the licensee.

Continue….
Open source licenses also do not contain the kind of representations and warranties of quality or fitness for a particular purpose
Some open source requires licensees to provide free copies of their derivative works in source code form for other to use, modify and redistribute.

Critique of the Open-Source Movement
Open-source project doesn’t attract a critical mass of developers, as a result quality can be poor
Without an ownership, incompatible version may arise
Open-source software as a whole trends to have a relatively weak graphical user interface
Poor mechanism for stimulating innovation.

Conclusion Open-Source offers opportunities and
disadvantages Opportunities
Vast pool of software talent with access to The ability to improve upon Open Source Software The ability to access and utilize software
Disadvantages Risk of Utilizing software No warranties Quality may not be up to the mark
