The Open Source Definition

                (Version 1.0)

Open source doesn't just mean access to the source code. The distribution
terms of an open-source program must comply with the following criteria:

1. Free Redistribution

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

2. Source Code

The program must include source code, and must allow distribution in source
code as well as compiled form. Where some form of a product is not
distributed with source code, there must be a well-publicized means of
downloading the source code, without charge, via the Internet. The source
code must be the preferred form in which a programmer would modify the
program. Deliberately obfuscated source code is not allowed. Intermediate
forms such as the output of a preprocessor or translator are not allowed.
(rationale)

3. Derived Works

The license must allow modifications and derived works, and must allow them
to be distributed under the same terms as the license of the original
software. (rationale)

4. Integrity of The Author's Source Code.

The license may restrict source-code from being distributed in modified form
only if the license allows the distribution of "patch files" with
the source
code for the purpose of modifying the program at build time. The license
must explicitly permit distribution of software built from modified source
code. The license may require derived works to carry a different name or
version number from the original software. (rationale)

5. No Discrimination Against Persons or Groups.

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

6. No Discrimination Against Fields of Endeavor.

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

7. Distribution of License.

The rights attached to the program must apply to all to whom the program is
redistributed without the need for execution of an additional license by
those parties. (rationale)

8. License Must Not Be Specific to a Product.

The rights attached to the program must not depend on the program's being
part of a particular software distribution. If the program is extracted from
that distribution and used or distributed within the terms of the program's
license, all parties to whom the program is redistributed should have the
same rights as those that are granted in conjunction with the original
software distribution. (rationale)

9. License Must Not Contaminate Other Software.

The license must not place restrictions on other software that is
distributed along with the licensed software. For example, the license must
not insist that all other programs distributed on the same medium must be
open-source software. (rationale)

10. Example Licenses.

The GNU GPL, BSD, X Consortium, and Artistic licenses are examples of
licenses that we consider conformant to the Open Source Definition. So are
the MPL and QPL.
