What is Open Source Software

1.

Software used to create IR and freely available for public under open source license and comply with OAI Metadata Harvesting Protocol released, such as DSpace and EPrints. Learn more in: Institutional Repository

2.

A model of software licensing whereby access to the source code is without limitations, including the right to modify it by users. The costs of its deployment are lower than for proprietary software and due to the culture of collaborative development, the level of customization and quality is usually high.

According to the Open Source Initiative, licenses must meet ten conditions in order to be considered open source licenses: 1) The software can be freely given away or sold; 2) The source code must either be included or freely obtainable; 3) Redistribution of modifications must be allowed; 4) Licenses may require that modifications be redistributed only as patches; 5) No discrimination against persons or groups; 6) No discrimination against fields of endeavor; 7) The rights attached to the program must apply to all to whom the program is redistributed without the need for execution of an additional license by those parties; 8) The program cannot be licensed only as part of a larger distribution; 9) The license cannot insist that any other software it is distributed with must also be open source; 10) License must be technology-neutral. The official definition of Open Source Software is very close to the definition of Free Software; however, it allows in practice more restrictive licenses, creating a category of “semi-free” software.

Generically, open source refers to a program in which the source code is available to the general public for use and/or modification from its original design free of charge. Open source code is typically created as a collaborative effort in which programmers improve upon the code and share the changes within the community.
