copyright - Debian Perl Group common copyright statements


INTRODUCTION

This is a small guide detailing some common copyright statements, which are used for many reasons. In particular, there are packages that are designed to generate files for inclusion in modules, such as Module::Install, AutoXS::Header and Devel::PPPort. These files have copyrights that may differ from the rest of the distribution, so it is important to cite them accordingly.

Contributions are welcomed, especially statements that are valid for earlier versions of the modules listed here.


Module::Install

COMMON LICENSES

This is some common license clauses that are not considered common enough to be included in `/usr/share/common-licenses/' (part of the base-files package; controlled by the Debian Policy Team). The guideline seems to be that there must be at least 250 packages using a license prior to inclusion.

Artistic License 2.0

This is the second version of the Artistic License. It is expected that this version will replace the current usage of the Artistic License (as is the recommendation of the Open Source Initiative), and it is indeed the license on all major Perl 6 implementations.

License: Artistic-2.0
    Copyright (c) 2000-2006, The Perl Foundation.
 .
    Everyone is permitted to copy and distribute verbatim copies of this
    license document, but changing it is not allowed.
 .
    Preamble
 .
    This license establishes the terms under which a given free software
    Package may be copied, modified, distributed, and/or redistributed.
    The intent is that the Copyright Holder maintains some artistic
    control over the development of that Package while still keeping the
    Package available as open source and free software.
 .
    You are always permitted to make arrangements wholly outside of this
    license directly with the Copyright Holder of a given Package. If the
    terms of this license do not permit the full use that you propose to
    make of the Package, you should contact the Copyright Holder and seek
    a different licensing arrangement.
 .
    Definitions
 .
    "Copyright Holder" means the individual(s) or organization(s) named in
    the copyright notice for the entire Package.
 .
    "Contributor" means any party that has contributed code or other
    material to the Package, in accordance with the Copyright Holder's
    procedures.
 .
    "You" and "your" means any person who would like to copy, distribute,
    or modify the Package.
 .
    "Package" means the collection of files distributed by the Copyright
    Holder, and derivatives of that collection and/or of those files. A
    given Package may consist of either the Standard Version, or a
    Modified Version.
 .
    "Distribute" means providing a copy of the Package or making it
    accessible to anyone else, or in the case of a company or
    organization, to others outside of your company or organization.
 .
    "Distributor Fee" means any fee that you charge for Distributing this
    Package or providing support for this Package to another party. It
    does not mean licensing fees.
 .
    "Standard Version" refers to the Package if it has not been modified,
    or has been modified only in ways explicitly requested by the
    Copyright Holder.
 .
    "Modified Version" means the Package, if it has been changed, and such
    changes were not explicitly requested by the Copyright Holder.
 .
    "Original License" means this Artistic License as Distributed with the
    Standard Version of the Package, in its current version or as it may
    be modified by The Perl Foundation in the future.
 .
    "Source" form means the source code, documentation source, and
    configuration files for the Package.
 .
    "Compiled" form means the compiled bytecode, object code, binary, or
    any other form resulting from mechanical transformation or translation
    of the Source form.
 .
    Permission for Use and Modification Without Distribution
 .
    (1) You are permitted to use the Standard Version and create and use
    Modified Versions for any purpose without restriction, provided that
    you do not Distribute the Modified Version.
 .
    Permissions for Redistribution of the Standard Version
 .
    (2) You may Distribute verbatim copies of the Source form of the
    Standard Version of this Package in any medium without restriction,
    either gratis or for a Distributor Fee, provided that you duplicate
    all of the original copyright notices and associated disclaimers. At
    your discretion, such verbatim copies may or may not include a
    Compiled form of the Package.
 .
    (3) You may apply any bug fixes, portability changes, and other
    modifications made available from the Copyright Holder. The resulting
    Package will still be considered the Standard Version, and as such
    will be subject to the Original License.
 .
    Distribution of Modified Versions of the Package as Source
 .
    (4) You may Distribute your Modified Version as Source (either gratis
    or for a Distributor Fee, and with or without a Compiled form of the
    Modified Version) provided that you clearly document how it differs
    from the Standard Version, including, but not limited to, documenting
    any non-standard features, executables, or modules, and provided that
    you do at least ONE of the following:
 .
    (a) make the Modified Version available to the Copyright Holder of the
    Standard Version, under the Original License, so that the Copyright
    Holder may include your modifications in the Standard Version. (b)
    ensure that installation of your Modified Version does not prevent the
    user installing or running the Standard Version. In addition, the
    Modified Version must bear a name that is different from the name of
    the Standard Version. (c) allow anyone who receives a copy of the
    Modified Version to make the Source form of the Modified Version
    available to others under (i) the Original License or (ii) a license
    that permits the licensee to freely copy, modify and redistribute the
    Modified Version using the same licensing terms that apply to the copy
    that the licensee received, and requires that the Source form of the
    Modified Version, and of any works derived from it, be made freely
    available in that license fees are prohibited but Distributor Fees are
    allowed.
 .
    Distribution of Compiled Forms of the Standard Version or Modified
    Versions without the Source
 .
    (5) You may Distribute Compiled forms of the Standard Version without
    the Source, provided that you include complete instructions on how to
    get the Source of the Standard Version. Such instructions must be
    valid at the time of your distribution. If these instructions, at any
    time while you are carrying out such distribution, become invalid, you
    must provide new instructions on demand or cease further distribution.
    If you provide valid instructions or cease distribution within thirty
    days after you become aware that the instructions are invalid, then
    you do not forfeit any of your rights under this license.
 .
    (6) You may Distribute a Modified Version in Compiled form without the
    Source, provided that you comply with Section 4 with respect to the
    Source of the Modified Version.
 .
    Aggregating or Linking the Package
 .
    (7) You may aggregate the Package (either the Standard Version or
    Modified Version) with other packages and Distribute the resulting
    aggregation provided that you do not charge a licensing fee for the
    Package. Distributor Fees are permitted, and licensing fees for other
    components in the aggregation are permitted. The terms of this license
    apply to the use and Distribution of the Standard or Modified Versions
    as included in the aggregation.
 .
    (8) You are permitted to link Modified and Standard Versions with
    other works, to embed the Package in a larger work of your own, or to
    build stand-alone binary or bytecode versions of applications that
    include the Package, and Distribute the result without restriction,
    provided the result does not expose a direct interface to the Package.
 .
    Items That are Not Considered Part of a Modified Version
 .
    (9) Works (including, but not limited to, modules and scripts) that
    merely extend or make use of the Package, do not, by themselves, cause
    the Package to be a Modified Version. In addition, such works are not
    considered parts of the Package itself, and are not subject to the
    terms of this license.
 .
    General Provisions
 .
    (10) Any use, modification, and distribution of the Standard or
    Modified Versions is governed by this Artistic License. By using,
    modifying or distributing the Package, you accept this license. Do not
    use, modify, or distribute the Package, if you do not accept this
    license.
 .
    (11) If your Modified Version has been derived from a Modified Version
    made by someone other than you, you are nevertheless required to
    ensure that your Modified Version complies with the requirements of
    this license.
 .
    (12) This license does not grant you the right to use any trademark,
    service mark, tradename, or logo of the Copyright Holder.
 .
    (13) This license includes the non-exclusive, worldwide,
    free-of-charge patent license to make, have made, use, offer to sell,
    sell, import and otherwise transfer the Package with respect to any
    patent claims licensable by the Copyright Holder that are necessarily
    infringed by the Package. If you institute patent litigation
    (including a cross-claim or counterclaim) against any party alleging
    that the Package constitutes direct or contributory patent
    infringement, then this Artistic License to you shall terminate on the
    date that such litigation is filed.
 .
    (14) Disclaimer of Warranty: THE PACKAGE IS PROVIDED BY THE COPYRIGHT
    HOLDER AND CONTRIBUTORS "AS IS' AND WITHOUT ANY EXPRESS OR IMPLIED
    WARRANTIES. THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A
    PARTICULAR PURPOSE, OR NON-INFRINGEMENT ARE DISCLAIMED TO THE EXTENT
    PERMITTED BY YOUR LOCAL LAW. UNLESS REQUIRED BY LAW, NO COPYRIGHT
    HOLDER OR CONTRIBUTOR WILL BE LIABLE FOR ANY DIRECT, INDIRECT,
    INCIDENTAL, OR CONSEQUENTIAL DAMAGES ARISING IN ANY WAY OUT OF THE USE
    OF THE PACKAGE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGE.

Creative Commons Zero (CC0)

Creative Commons Zero is a permissive license akin to Public Domain, but with fewer issues when countries do not permit authors to release their work into the public domain. It is designed to be a license for literary and artistic works, rather than software; as such, it's not often used for software.

License: CC0
    The laws of most jurisdictions throughout the world
    automatically confer exclusive Copyright and Related Rights
    (defined below) upon the creator and subsequent owner(s)
    (each and all, an "owner") of an original work of authorship
    and/or a database (each, a "Work").
 .
    Certain owners wish to permanently relinquish those rights
    to a Work for the purpose of contributing to a commons of
    creative, cultural and scientific works ("Commons") that the
    public can reliably and without fear of later claims of
    infringement build upon, modify, incorporate in other works,
    reuse and redistribute as freely as possible in any form
    whatsoever and for any purposes, including without
    limitation commercial purposes. These owners may contribute
    to the Commons to promote the ideal of a free culture and
    the further production of creative, cultural and scientific
    works, or to gain reputation or greater distribution for
    their Work in part through the use and efforts of others.
 .
    For these and/or other purposes and motivations, and without
    any expectation of additional consideration or compensation,
    the person associating CC0 with a Work (the "Affirmer"), to
    the extent that he or she is an owner of Copyright and
    Related Rights in the Work, voluntarily elects to apply CC0
    to the Work and publicly distribute the Work under its
    terms, with knowledge of his or her Copyright and Related
    Rights in the Work and the meaning and intended legal effect
    of CC0 on those rights.
 .
    1. Copyright and Related Rights. A Work made available under
    CC0 may be protected by copyright and related or neighboring
    rights ("Copyright and Related Rights"). Copyright and
    Related Rights include, but are not limited to, the
    following:
 .
        1. the right to reproduce, adapt, distribute, perform,
        display, communicate, and translate a Work;
 .
        2. moral rights retained by the original author(s)
        and/or performer(s);
 .
        3. publicity and privacy rights pertaining to a
        person's image or likeness depicted in a Work;
 .
        4. rights protecting against unfair competition in
        regards to a Work, subject to the limitations in
        paragraph 4(a), below;
 .
        5. rights protecting the extraction, dissemination, use
        and reuse of data in a Work;
 .
        6. database rights (such as those arising under
        Directive 96/9/EC of the European Parliament and of the
        Council of 11 March 1996 on the legal protection of
        databases, and under any national implementation
        thereof, including any amended or successor version of
        such directive); and
 .
        7. other similar, equivalent or corresponding rights
        throughout the world based on applicable law or treaty,
        and any national implementations thereof.
 .
    2. Waiver. To the greatest extent permitted by, but not in
    contravention of, applicable law, Affirmer hereby overtly,
    fully, permanently, irrevocably and unconditionally waives,
    abandons, and surrenders all of Affirmer's Copyright and
    Related Rights and associated claims and causes of action,
    whether now known or unknown (including existing as well as
    future claims and causes of action), in the Work
 .
        (i) in all territories worldwide,
 .
        (ii) for the maximum duration provided by applicable
        law or treaty (including future time extensions),
 .
        (iii) in any current or future medium and for any
        number of copies, and
 .
        (iv) for any purpose whatsoever, including without
        limitation commercial, advertising or promotional
        purposes (the "Waiver"). Affirmer makes the Waiver for
        the benefit of each member of the public at large and
        to the detriment of Affirmer's heirs and successors,
        fully intending that such Waiver shall not be subject
        to revocation, rescission, cancellation, termination,
        or any other legal or equitable action to disrupt the
        quiet enjoyment of the Work by the public as
        contemplated by Affirmer's express Statement of
        Purpose.
 .
    3. Public License Fallback. Should any part of the
    Waiver for any reason be judged legally invalid or
    ineffective under applicable law, then the Waiver shall
    be preserved to the maximum extent permitted taking
    into account Affirmer's express Statement of Purpose.
    In addition, to the extent the Waiver is so judged
    Affirmer hereby grants to each affected person a
    royalty-free, non transferable, non sublicensable, non
    exclusive, irrevocable and unconditional license to
    exercise Affirmer's Copyright and Related Rights in the
    Work
 .
        (i) in all territories worldwide,
 .
        (ii) for the maximum duration provided by applicable
        law or treaty (including future time extensions),
 .
        (iii) in any current or future medium and for any
        number of copies, and
 .
        (iv) for any purpose whatsoever, including without
        limitation commercial, advertising or promotional
        purposes (the "License"). The License shall be deemed
        effective as of the date CC0 was applied by Affirmer to
        the Work. Should any part of the License for any reason
        be judged legally invalid or ineffective under
        applicable law, such partial invalidity or
        ineffectiveness shall not invalidate the remainder of
        the License, and in such case Affirmer hereby affirms
        that he or she will not
 .
            (i) exercise any of his or her remaining Copyright
            and Related Rights in the Work or
 .
            (ii) assert any associated claims and causes of
            action with respect to the Work, in either case
            contrary to Affirmer's express Statement of
            Purpose.
 .
    4. Limitations and Disclaimers.
 .
        1. No trademark or patent rights held by Affirmer are
        waived, abandoned, surrendered, licensed or otherwise
        affected by this document.
 .
        2. Affirmer offers the Work as-is and makes no
        representations or warranties of any kind concerning the
        Work, express, implied, statutory or otherwise, including
        without limitation warranties of title, merchantability,
        fitness for a particular purpose, non infringement, or the
        absence of latent or other defects, accuracy, or the present
        or absence of errors, whether or not discoverable, all to
        the greatest extent permissible under applicable law.
 .
        3. Affirmer disclaims responsibility for clearing rights of
        other persons that may apply to the Work or any use thereof,
        including without limitation any person's Copyright and
        Related Rights in the Work. Further, Affirmer disclaims
        responsibility for obtaining any necessary consents,
        permissions or other rights required for any use of the
        Work.
 .
        4. Affirmer understands and acknowledges that Creative
        Commons is not a party to this document and has no duty or
        obligation with respect to this CC0 or use of the Work.


MISSING INFORMATION

Sometimes an upstream author will be missing some or all of the information required. It is important to have all of the copyright information; for new packages, the ftp-master team will reject packages that do not have proper copyright and licensing information. It's important to do this in order to ensure we comply with Debian Free Software Guidelines. Here is a sample message you can use.

CPAN Request Tracker

Hi:

While packaging your module, for Debian, I noticed that it doesn't seem to mention [copyright information, or license information, or both].

In Debian we need copyright/license information for all of the packages we upload. Could you give us (replying to this bug report is fine): years of copyright, copyright holders' names, copyright holders' e-mail addresses. Unfortunately without this information we cannot upload it.

This is more than just a Debian issue. I'm not a lawyer, but it's my understanding that both copyright and licensing information is vital for the continued success of open source software. Copyright is what allows you to assert a license, and a license is what ensures open source remains open source, and that users can make use of your software. A great article discussing some of this is "What is Copyleft?" by Richard Stallman: http://www.gnu.org/copyleft/

Thanks for releasing your work to the CPAN. I apologize in advance for the noise, as I understand that the last thing most authors want to deal with is legal administrivia like this. I do hope, however, that you could (in your continued generosity) help us with this request. Please also consider adding these statements to your code/package README, since we must distribute some evidence of copyright information if it is not in the source package itself.

Cheers, [Your Name] On behalf of the Debian Perl Team
