Open source software system

The open source system is an approach towards free development and expansion of softwares. By the end of 1990s, in reaction to creation of monopoly in software production by the intellectual property system, this approach came into existence. Free transfer of source code along with its software and the possibility of free reproduction, distribution, modification and redistribution of the modified version are among the basic principles of this approach. The ten principles of open source system are in contrast with the principles governing intellectual property system. Academic licenses, reciprocal and standard, are the most widely used open source licenses. Another principle is the option of software commercial exploitation by way of open source licenses. According to the advantages of open source system in protecting softwares, it is required some modifications in intellectual property principles affected by open source roles.
