The Open Source Definition

Introduction

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

1. Free Redistribution

The license shall 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 shall not require a
royalty or other fee for such sale.

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 obtaining the source code for no more
than a reasonable reproduction cost preferably, downloading via
the Internet without charge. 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.

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.

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.

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
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.

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.

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.

9. License Must Not Restrict 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.

*10. License Must Be Technology-Neutral

No provision of the license may be predicated on any individual
technology or style of interface.
