Through universal communication networks, hundreds of millions of human beings today have the ability to access, modify, author, publish and distribute artistic works, scientific and educational materials, commentary, reports, and documents; in short: anything that can be represented as a sequence of bits. In many cases, however, we find that traditional copyright laws, which provide authors and artists with decades of protection even beyond their death, can impede cultural and scientific progress.
Works built by communities collaborating as volunteers, art created for the purpose of shared enjoyment, essential learning materials, scientific research funded through taxpayer money, and many other works do not benefit from artificial scarcity. They benefit from being used freely. We therefore believe that these works should be free, and by "freedom" we mean:
- the freeto study the work and to apply knowledge acquired from it
- the freedom to redistribute copies, in whole or in part, of the information or expression
- the freedom to make improvements or other changes, and to release modified copies
These freedoms should be universally available to absolutely anyone, anywhere. To the extent possible, they should not be restricted by the context in which the work is used.
Any original work of authorship is copyrighted. Under copyright law, authors are considered God-like "creators" and are given legal powers they can use against those who duplicate "their" content in altered or unaltered form. Only very limited freedoms are granted to others unless authors choose to explicitly relinquish some or all of these powers. To do so, authors can explicitly release their work into the public domain (no copyright)1, or can choose among a vast array of legal documents known as licenses to grant, retain or qualify their exclusive rights.
Not all licenses grant the freedoms enumerated above. For example, some popular licenses forbid the creation of derivative works, or the commercial use of a work. Some licenses are even more specific. They limit usage of the work to particular regions of the world, or to relative quantities of information.
However,work can be truly called "free" unless it can be freely shared, freely modified, freely aggregated, freely combined, and freely provided through any channel. Works under licenses that prohibit these essential freedoms stand seperate from the body of works that is not impeded by these restrictions. They are philosophically and legally incompatible with the licensing options used by the growing movement that refers to its works as "free content" or "free expression."
Any license which requires the term "ree" to be significantly qualified ("it is free, but you cannot ..") can only mean "free" in the sense of "gratis, without cost". It can never mean that every essential freedom is present. It is the goal of this definition to precisely define the essential freedoms, and to provide guidelines by which existing licenses can be certified as meeting this definition.
Naming and versioning
You may refer to this definition as the "Free Content and Expression Definition" (its full name), the "Free Content Definition", or the "Free Expression Definition". Consequently, you may call a work covered by this definition "free content" or (a) "free expression" (the terms may or may not be capitalized). Which name should you use? summarizes some arguments for and against the two names and possible alternatives.
New versions of this definition shall be released as soon as a consensus (achieved directly or through a vote, as per the authoring process) has developed around suggested changes. Numbering shall be 0.x for initial draft releases, 1.x, 2.x .. for major releases, x.1, x.2 .. for minor releases. A minor release is made when the text is modified in ways which do not have an impact on the scope of existing or hypothetical licenses covered by this definition.
In order to be recognized as "free" under this definition, a license must grant the following freedoms without limitation:
- The freedom to study and apply the information: The licensee must not be restricted by clauses which limit their right to examine, alter or apply the information. The license may not, for example, restrict "reverse engineering", and it may not limit the application of knowledge gained from the work in any way.
- The freedom to redistribute copies: Copies may be sold, swapped or given away for free, as part of a larger work, a collection, or independently. There must be no limit on the amount of information that can be copied. There must also not be any limit on who can copy the information or on where the information can be copied.
- The freedom to distribute modified versions: In order to give everyone the ability to improve upon a work, the license must not limit the freedom to distribute a modified version, as above, regardless of the intent and purpose of such modifications. However, some restrictions may be applied to protect these essential freedoms, as well as the requirement of attribution (see below).
Authors of licenses should make an effort to gradually make licenses which share the same philosophical roots and legal principles compatible with each other to ensure that works under these licenses can be combined and aggregated freely. This may be accomplished by altering the terms of the license (e.g. by removing a restriction which the other license does not have), or by adding migration clauses which allow the use of the licensed work under the now compatible license.
When making copies of a work, the licensee should be allowed to refer to a resource pointer instead of being required to distribute the license text itself with each copy of the work. Similarly, the license should allow the author or authors to specify a resource pointer for the attribution of multiple authors of a work. This is to ensure that the attribution requirement for complex collaborative works does not become an impediment.
- Under some jurisdictions, notably some European countries, authors have inalienable moral rights and cannot completely release their works into the public domain. If you believe that you have a right to put your own works in the public domain, regardless of what the law says, you can make a declaration of public domain status which contains a safeguard clause, such as: "I, the author of this work, hereby release it into the public domain. This applies worldwide. In case this is not legally possible: I grant anyone the right to use this work for any purpose, without any conditions, unless such conditions are required by law."
