What is open source methodology

Open source

The English term open source, which translates as "free source", describes a concept according to which programs are delivered with their source code. So everyone can see the source code and change it. A special initiative, the Open Source Initiative (OSI), is responsible for defining criteria that open source software should meet.

With the label Open source This means the free availability of software source codes, which can be used and changed free of charge within the framework of open source license models. The term arose at the same time as the Open Source Initiative (OSI) was founded in 1998 and has shaped the image of software development ever since.
The terms “free software” and “open software” are often used in the literature in connection with open source software (OSS).
It is pointed out again that the respective software can be used, copied and distributed by everyone. This happens either free of charge or for a fee. The source code should only be available to anyone interested. The fee is not a license fee for software, just a provision to cover the vendor's costs.
Open source software comes in different forms. The name can be projects, distribution systems or platformers. An open source project usually consists of several applications, such as Mozilla, which is an open source project that contains a number of applications, including the Internet browser Firefox.

The four defining characteristics of open source software (OSS)

The four characteristic features of open source software are the license of the software, the non-commercial settings, the high degree of collaboration in program development and the large spatial distribution of the developers.

Open source as opposed to proprietary software

The form of the proprietary software, the peculiar software, stands in contrast to the open source concept. In order to use, distribute, redistribute or modify proprietary software, authorization from the software owner is required.

Necessity and difficulty of registering the open source software


Open source is considered a description and for this reason cannot be registered as a trademark or trademark, since the respective licenses are not goods and therefore not with the U.S. Patent and Trademark Office can be registered. However, this registration is necessary to support the needs of the free software community. For example, the Open Source Initiative (OSI) had a so-called “certification mark” registered as a seal of approval after it was looking for a reliable name for open source software. If the seal of approval “OSI certified” appears on a software, it is under a license that is consistent with the open source definition.
The seal of approval can only be applied to software and not to licenses. This is to ensure that a software package with the included licenses is an open source distribution.
The open source software is a combination of the existing knowledge about software development, sales and organizations with the effects of the internet economy. This increasing standardization of license-free software interfaces and formats will decrease the importance of the previous proprietary software solutions.

Investigation of various open source projects

VisionMobile, a market research company, has examined the openness of eight software projects that work according to the principles of open source. The EU co-financed this study and an Open Governance Index was designed, which is to be rated according to openness, according to points of accessibility, development, transparency, further development and community system. In this way, it can be quantified how open or closed such a project is.


The Qt, Symbian, MeeGo, Mozilla, WebKit and Linux projects are an example of the one open source that works according to the open source principle. The world's best-known and most successful example of the open source idea is the Wikipedia encyclopedia, which anyone can work on, making it the largest collection of knowledge in the world.
