 regime applies to any derived works. It is an explicit “feature” of open source that it may put no restrictions on the use or distribution by any organization or user. It forbids this, in principle, to guarantee continued access to derived works even by the major original contributors.

Proliferation of the term

While the term applied originally only to the source code of software, it is now being applied to many other areas such as open source ecology, a movement to decentralize technologies so that any human can use them. However, it is often misapplied to other areas which have different and competing principles, which overlap only partially.

Opponents of the spread of the label “open source,” including Richard Stallman

Richard Matthew Stallman , often abbreviated "rms","'Richard Stallman' is just my mundane name; you can call me 'rms'"|last= Stallman...
, argue that the requirements and restrictions ensure the continuation of the effort, and resist attempts to redefine the labels. He argues also that most supporters of open source are actually supporters of much more equitable agreements and support re-integration of derived works and that most contributors do not intend to release their work to others who can extend it, hide the extensions, patent those very extensions, and demand royalties or restrict the use of all other users—all while not violating the open source principles with respect to the initial code they acquired.

Business models

There are a number of commonly recognized barriers to the adoption of open source software by enterprises. These barriers include the perception that open source licenses are viral, lack of formal support and training, the velocity of change, and a lack of a long term roadmap. The majority of these barriers are risk-related. From the other side, not all proprietary projects disclose exact future plans, not all open source licenses are equally viral and many serious OSS projects (especially operating systems) actually make money from paid support and documentation.

 and technology ownership, the result is an increase in general population's access to digital media. This phenomenon facilitated growth in open source culture because it allowed for rapid and inexpensive duplication and distribution of culture. Where the access to the majority of culture produced prior to the advent of digital media was limited by other constraints of proprietary and potentially "open" mediums, digital media is the latest technology with the potential to increase access to cultural products. Artists and users who choose to distribute their work digitally face none of the physical limitations that traditional cultural producers have been typically faced with. Accordingly, the audience of an open source culture faces little physical cost in acquiring digital media.

 is open source culture's most valuable asset. It is questionable whether the goals of an open source culture could be achieved without the Internet. The global network not only fosters an environment where culture can be generally accessible, but also allows for easy and inexpensive redistribution of culture back into various communities. Some reasons for this are as follows.

First, the Internet allows even greater access to inexpensive digital media and storage. Instead of users being limited to their own facilities and resources, they are granted access to a vast network of facilities and resources, some for free. Sites such as Archive.org offer up free web space for anyone willing to license their work under a Creative Commons

 have limitations on the kind of interaction users can have. In the case of television there is little, if any interaction between users participating on the network. And in the case of the telephone, users rarely interact with any more than a couple of their known peers. On the Internet, however, users have the potential to access and meet millions of their peers. This aspect of the Internet facilitates the modification of culture as users are able to collaborate and communicate with each other across international and cultural boundaries. The speed in which digital media travels on the Internet in turn facilitates the redistribution of culture.

Through various technologies such as peer-to-peer

Ethics

Open Source ethics is split into two strands:

  • Open Source Ethics as a Professional Body of Rules - This is based principally on the computer ethics school, studying the questions of ethics and professionalism in the computer industry in general and software development in particular.

Linux

Linux is a generic term referring to Unix-like computer operating systems based on the Linux kernel.

, utilize open source software that is open to the public and can be modified by users to fit their own tastes. Whether the code is open or not, this format represents a nimble tool for people to borrow and re-present culture; whereas traditional websites made the illegal reproduction of culture difficult to regulate, the mutability of blogs makes "open sourcing" even more uncontrollable since it allows a larger portion of the population to replicate material more quickly in the public sphere.

Messageboards are another platform for open source culture. Messageboards (also known as discussion boards or forums), are places online where people with similar interests can congregate and post messages for the community to read and respond to. Messageboards sometimes have moderators who enforce community standards of etiquette such as banning users who are spammers. Other common board features are private messages (where users can send messages to one another) as well as chat (a way to have a real time conversation online) and image uploading. Some messageboards use phpBB
PhpBB

phpBB is a popular Internet forum package written in the PHP scripting language. The name "phpBB" is an abbreviation of PHP Bulletin Board. Available under the GNU General Public License, phpBB is free software....
, which is a free open source package. Where blogs are more about individual expression and tend to revolve around their authors, messageboards are about creating a conversation amongst its users where information can be shared freely and quickly. Messageboards are a way to remove intermediaries from everyday life - for instance, instead of relying on commercials and other forms of advertising, one can ask other users for frank reviews of a product, movie or CD. By removing the cultural middlemen, messageboards help speed the flow of information and exchange of ideas.

Open source movie production is either an open call system in which a changing crew and cast collaborate in movie production, a system in which the end result is made available for re-use by others or in which exclusively open source products are used in the production. The 2006 movie Elephants Dream

By doing so, on-line contributors become part of the process of creating the film, helping to influence the editorial and visual material to be used in the documentary, as well as its thematic development. The first open source documentary film to go into production ," which will examine the role that WBCN-FM in Boston played in the cultural, social and political changes locally and nationally from 1968 to 1974, is being produced by Lichtenstein Creative Media and the non-profit The Fund for Independent Media. is a website to create Basement Tapes, a feature documentary about copyright in the digital age, co-produced by the . Open Source Filmmaking refers to a form of filmmaking that takes a method of idea formation from open source software, but in this case the 'source' for a film maker is raw unedited footage rather than programming code. It can also refer to a method of filmmaking where the process of creation is 'open' i.e. a disparate group of contributors, at different times contribute to the final piece.

Another strand to the academic community is in the area of research. Many funded research projects produce software as part of their work. There is an increasing interest in making the outputs of such projects available under an open source license. In the UK the Joint Information Systems Committee (JISC) has developed a policy on open source software. JISC also funds a development service called OSS Watch

Innovation communities

The principle of sharing predates the open source movement; for example, the free sharing of information has been institutionalized in the scientific enterprise since at least the 19th century. Open source principles have always been part of the scientific community. The sociologist Robert K. Merton
Robert K. Merton

Robert King Merton was a distinguished American sociologist perhaps best known for having coined the phrase "self-fulfilling prophecy." He also coined many other phrases that have gone into everyday use, such as "role model" and "unintended consequences"....
 described the four basic elements of the community - universalism (an international perspective), communism (sharing information), disinterestedness (removing one's personal views from the scientific inquiry) and organized skepticism (requirements of proof and review) that accurately describe the scientific community today. These principles are, in part, complemented by US law's focus on protecting expression and method but not the ideas themselves. There is also a tradition of publishing research results to the scientific community instead of keeping all such knowledge proprietary. One of the recent initiatives in scientific publishing has been open access
Open access

Open access -- free online access -- can be provided in two ways: open access publishing and open access self-archiving, by its authors, of non-open-access publications ....
 - the idea that research should be published in such a way that it is free and available to the public. There are currently many open access journals where the information is available for free online, however most journals do charge a fee (either to users or libraries for access). The Budapest Open Access Initiative is an international effort with the goal of making all research articles available for free on the Internet. The National Institutes of Health
National Institutes of Health

The National Institutes of Health is an agency of the United States Department of Health and Human Services and is the primary agency of the United States government responsible for biomedical and health-related research....
 has recently proposed a policy on "Enhanced Public Access to NIH Research Information." This policy would provide a free, searchable resource of NIH-funded results to the public and with other international repositories six months after its initial publication. The NIH's move is an important one because there is significant amount of public funding in scientific research. Many of the questions have yet to be answered - the balancing of profit vs. public access, and ensuring that desirable standards and incentives do not diminish with a shift to open access.

Farmavita.Net - Community of Pharmaceuticals Executives have recently proposed new business model of Open Source Pharmaceuticals . The project is targeted to development and sharing of know-how for manufacture of essential and life saving medicines. It is mainly dedicated to the countries with less developed economies where local pharmaceutical research and development resources are insufficient for national needs. It will be limited to generic (off-patent) medicines with established use. By the definition, medicinal product have a “well-established use” if is used for at least 15 years, with recognized efficacy and an acceptable level of safety. In that event, the expensive clinical test and trial results could be replaced by appropriate scientific literature.

Certification


In order to build higher user confidence, certification is mandatory. Certification could be applied to the simplest component that can be used by developers to build the simplest module to a whole software system. There have been numerous institutions involving in this area of the open source software including The International Institute of Software Technology / United Nations University (http://www.iist.unu.edu). UNU/IIST is a non-profit research and education institution of The United Nations. It is currently involved in a project known as "The Global Desktop Project". This project aims to build a desktop interface that every end-user is able to understand and interact with, thus crossing the language and cultural barriers. It is drawing huge attention from parties involved in areas ranging from application development to localization. Furthermore, this project will improve developing nations' access to information systems. UNU/IIST aims to achieve this without any compromise in the quality of the software. It believes a global standard can be maintained by introducing certifications and is currently organizing conferences in order to explore frontiers in the field (http://opencert.iist.unu.edu).

ed to the detriment of the individual contributors/authors.

Another criticism of the Open Source movement is that these projects may not be really as self-organizing as their proponents claim. This argument holds that successful Open Source projects frequently have a strong central manager, even if that manager is a volunteer. The article by Chuck Connell explains this viewpoint. However this is a criticism of the development model, not of the Open Source itself. Also, the author does not state that self organization surely does not work, just points to the cases when the central management was likely involved.

The legal and cultural criticisms are both addressed as part of a common set of objections and criticisms by those who prefer share-alike
