"'All' is excessive."
Simply put, "copyleft" is all things related to alternative intellectual property models that are less restrictive, but more complex than the classical concept of a copyright.  If a creative work has been "copylefted," then the creator of that work undoubtedly has chosen to be more permissive with what others may do with that work.  All rights ''not'' reserved, as it were.  This is not the same as declaring a work part of the [http://en.wikipedia.org/wiki/Public_domain public domain], in which all rights are relinquished.  The concept is best visualized in [http://creativecommons.org/about/ this spectrum graphic] presented on the Creative Commons website.

Alternative Intellectual Property Models

Creative Commons and the GNU General Public License are two alternative intellectual property models that are used in the software industry, and are now becoming more frequently used for non-software projects. Organizations and projects like Lulu, Wikibooks, and Flickr, utilize these alternative models and facilitate the creation of intellectual works. Examine the ethical considerations surrounding the practice of self-publishing and creation of collaborative works under alternative licenses.

Copyright vs. Copyleft

Simply put, "copyleft" is all things related to alternative intellectual property models that are less restrictive, but more complex than the classical concept of a copyright. If a creative work has been "copylefted," then the creator of that work undoubtedly has chosen to be more permissive with what others may do with that work. All rights not reserved, as it were. This is not the same as declaring a work part of the public domain, in which all rights are relinquished. The concept is best visualized in this spectrum graphic presented on the Creative Commons website.

Origins

Copyleft was popularized as a direct result of complex frustrations of software developers with existing copyright laws and practices during the 1970s. Richard Stallman, of the Free Software Foundation, who valued the free and open exchange of ideas wanted to preserve the environment that he experienced while working at MIT's AI Lab in the early 1970's. During that period, software vendors stopped shipping their products with the source code included, instead distributing the compiled executables, thus making user modification or improvement impossible. The intended purpose of this new practice was to help prevent unauthorized/unlicensed use of their intellectual property. Stallman's reaction to this, was to work within the established rule of law to present an alternative view of software development and innovation, thus creating the GNU Project and eventually the GNU General Public License.

GPL (GNU General Public License)

Synopsis

The GNU or General Public License, now in its third version, is a licesne primarily used by GNU programmers and programmers developing free software packages. The license was written by Richard Stallman for the GNU project. The GNU project is an operating system that in Unix-like in way it looks, but it is composed of all free software. The GPL it self is a great example of a copyleft license with requires derived works form the project to be available under the same copyleft license. The GPL grants the user of the software free software definition. The means that the user is free to copy the software, change the software, and redistribute the software.

Creative Commons License

Synopsis

Creative Commons is a Tax-Exempt charitable organization dedicated to defining the range of possibilities between full copyright and public domain. Their licenses offer a "some rights reserved" copyright. The corporations goals are cooperative and community-minded in a voluntary method.

Optional Conditions

Attribution: Non-commercial: No Derivatives: Share Alike:

License Expression

There are three methods for the license to be expressed for the work.

  • Common Deed - plain-language summary of the license with icons.
  • Legal Code - fine print that will ensure the license will stand up in court.
  • Digital Code - Machine-readable translation that helps search engines and other applications identify the work by its terms.

Licensing in the Wild

Public attitudes on the nature of intellectual property are constantly evolving, and so the diversity of copyright licenses that creators attach to their works increases constantly. The complexity and differentiation amongst these licenses upon works seem to show that creators do not agree that "all rights reserved" is the optimal attitude to adopt at publication time. When a creator makes the decision to publish their work, they may decide to use an existing license from this license bestiary from GNU, to draft their own license, or avoid license-language altogether by reserving all rights, and instead dealing with any public inquiries strictly upon request.
