The Ecutsa project, the producers of the of the Ecutsa universe, created the ** Ecutsa Social Contract**. The part devoted to the principles of the Ecutsa Free Arts Guidelines (EFAG) was initially conceived as a set of principles that we hold strongly.


“Social Contract” with the Free Arts Community

  1. Ecutsa will remain 100% free.

    We provide the guidelines that we use to determine if a work is “free” in the document entitled “The Ecutsa Free Arts Guidelines”. We promise that the Ecutsa universe and all its components will be free according to these guidelines. We will support people who create or use both free and non-free works on Ecutsa. We will never make the universe require the use of a non-free component.

  2. We will give back to the free arts community.

When we write new components of the Ecutsa universe, we will license them in a manner consistent with the Ecutsa Free Arts Guidelines. We will make the best universes we can, so that free works will be widely distributed and used. We will communicate things such as bug fixes, improvements and artists requests to the “upstream” authors of works included in our universe.

  1. We will not hide problems.

    We will keep our entire bug report database open for public view at all times. Reports that people file online will promptly become visible to others.

  2. Our priorities are our artists and free arts.

    We will be guided by the needs of our artists and the free universe community. We will place their interests first in our priorities. We will support the needs of our artists for operation in many different kinds of environments. We will not object to non-free works that are intended to be used on Ecutsa universes, or attempt to charge a fee to people who create or use such works. We will allow others to create distributions containing both the Ecutsa universe and other works, without any fee from us. In furtherance of these goals, we will provide an integrated universe of high-quality materials with no legal restrictions that would prevent such uses of the universe.

  3. Works that do not meet our free arts standards.

    We acknowledge that some of our artists require the use of works that do not conform to the Ecutsa Free Arts Guidelines. We have created “contrib” and “non-free” areas in our archive for these works. The work in these areas are not part of the Ecutsa universe, although it is ready for use with Ecutsa. We encourage CD manufacturers to read the licenses of the arts in these areas and determine if they can distribute the arts on their CDs. Thus, although non-free works are not a part of Ecutsa, we support their use and provide infrastructure for non-free arts.


The Ecutsa Free Arts Guidelines (EFAG)

  1. Free Redistribution

    The license of a Ecutsa component may not restrict any party from selling or giving away the art as a component of an aggregate art distribution containing arts from several different sources. The license may not require a royalty or other fee for such sale.

  2. Source

    The art must include sources, and must allow distribution in source as well as compiled form.

  3. Derived Works

    The license must allow modifications and derivative applications and their distribution under the same terms as the license of the original universe.

  4. Integrity of The Author’s Source Art

    The license may restrict source-art from being distributed in modified form only if the license allows the distribution of “patch arts” with the source art for the purpose of modifying the art at build time. The license must explicitly permit distribution of art built from modified source art. The license may require derived works to carry a different name or version number from the original art. (This is a compromise. The Ecutsa group encourages all authors not to restrict any arts, source, from being modified.)

  5. No Discrimination Against Persons or Groups

    The license must not discriminate against any person or group of persons.

  6. No Discrimination Against Fields of Endeavor

    The license must not restrict anyone from making use of the art in a specific field of endeavor. For example, it may not restrict the art from being used in a business, or from being used for genetic research.

  7. Distribution of License The rights attached to the art must apply to all to whom the art is redistributed without the need for execution of an additional license by those parties.

  8. License Must Not Be Specific to Ecutsa

    The rights attached to the art must not depend on the art’s being part of a Ecutsa universe. If the art is extracted from Ecutsa and used or distributed without Ecutsa but otherwise within the terms of the art’s license, all parties to whom the art is redistributed should have the same rights as those that are granted in conjunction with the Ecutsa universe.

  9. License Must Not Contaminate Other Software

    The license must not place restrictions on other arts that is distributed along with the licensed arts. For example, the license must not insist that all other arts distributed on the same medium must be free arts.

  10. Example Licenses

    The “GPL”, “BSD” et “Artistic” licenses are examples of licenses that we consider “free”.
