                                     Open source is a philosophy which suggests that the source code behind something should be freely available to the public. The principle originated in the software industry in the late 1990s, with several releases of open source software and operating systems, and it has since diffused into other communities as well. There are a number of strong arguments for releasing something in open source format, whether it be a recording, a software tool, or an entire operating system.
The main advantage to open source is that it allows end users to directly interact with the source, potentially modifying it to suit their wishes. This encourages constant development and innovation, while also creating a community of shared information. Many companies which produce open source products rely on the innovations of users to expand features and to identify and fix potential weak points, and these companies actively encourage modification of their products.
There are varying levels of open source. In some cases, for example, an open source release may have certain restrictions, in which case some people prefer the term “shared source,” or “shared commons.” For example, someone may release a recording in open source format, but ask people not to profit from their retooling of the album. Many advocates of the open source philosophy prefer truly open source, allowing people to do whatever they want with the source code and the end product.
Some people mistakenly believe that all open source material is also automatically free. This is not, in fact, the case. Several companies manufacture open source products which require people to pay for them, with the fees supporting development of new products and additional features. It is also common to see shared source licenses on things which people pay for. Apple Computer, for example, releases some of its technology under open source licenses.
Open Source has its critics, especially in the intellectual property community. Most of these critics argue that for open source development and distribution to really work, a strong central organizer is needed, and it is not unreasonable for major developers to expect compensations for their work on open source projects. When material is truly open source, however, it is challenging to figure out how to structure such compensations, and this often leads to tangled issues with shared licenses and restrictions which some people find chafing.
