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
"'All' is excessive."
What is Copyleft?
All wrongs reserved.
Some History
TinyBASIC, Stallman, EFF, GNU, etc.
GPL (GNU General Public License)
Synopsis
The GNU or General Public License, now in its third version, is a licsene primaraly used by GNU programers 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 dervied works form the project to be avalible under the same copyleft licence. 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.
Related Licenses
- GNU Lesser General Public License - is also a free software license that is a compromise between the original GPL and other permissive licenses. The main difference between GPL and LGPL programs is that LGPL programs can be linked to non GPL programs. Then the non GPL program can then be resdistributed as long as it is not a derivitve work. If it is it has to account for reverse engineering and debugging.
- GNU Free Documentation License - is a copyleft license for free documentation. It gives the readers the ability to copy, reddistribute,modify a work, and that all derivative works be avalible under the same license. Copys can actully be sold but if more than 100 copies are made the source code must be made avalible. The Free Documentation License is mostly used for manuals, textbooks and other refrence materials, it is also the license that Wikipedia uses.
- Affero General Public License - a free software license with a strong copyleft background, dealing with network server software. Very similar to the GPL, except that it makes the user have to have the source code avalible to any networked user of the AGPLed work.
Creative Commons License
All Rights Reserved vs. Public Domain. CC = "some rights reserved". Start here: http://creativecommons.org/about/license/ Think about and discuss implications.
