Artistic License 2.0

لایسنس Artistic License 2.0 یک لایسنس copyleft متوسط است که توسط Perl Foundation ایجاد شده است. این لایسنس برای پروژه‌های نرم‌افزاری طراحی شده که نیاز به تعادل بین آزادی و کنترل دارند.

ویژگی ها

تفاوت با سایر لایسنس‌ها

Artistic License 2.0 نسبت به GPL انعطاف‌پذیرتر است و اجازه استفاده در نرم‌افزارهای اختصاصی را می‌دهد، اما تغییرات در خود نرم‌افزار باید تحت همین لایسنس منتشر شوند.

Artistic License 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.

"Distribute with Other Software" 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, in conjunction with other software.

"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 option, such copies may also be in Compiled form.

(3) You may apply any bug fixes, portability fixes and other modifications derived from the Contributor Version to the Standard Version, resulting in a Modified Version. You may Distribute the Modified Version as a Standard Version, provided that you include a prominent notice that the Modified Version differs from the Standard Version, 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 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

(4) 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.

(5) 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

(6) You may create a Larger Work by combining the Package with other software and Distribute the Larger Work as a single product. In such case, you must make sure the requirements of this Artistic License are fulfilled for the Package.

Items That are Not Considered Part of a Modified Version

(7) Merging in a cover work (such as a logo, header, or footer) will not be considered a modification of the Package, provided that you do at least ONE of the following:

(a) duplicate the cover work verbatim without modification (excluding pre-compiled binaries, if any) to the top or bottom of each file of the Package, or

(b) rename any non-standard executables so that the names do not conflict with standard executables, and provide a separate manual page for each such executable that clearly documents how it differs from the Standard Version, or

(c) make the distribution of the cover work separate from the Package, or

(d) make the cover work a clearly separate work that is not intended to be a replacement for any part of the Package, and is not included in the Package.

Acceptance of the License

(8) The rights granted under this license take effect only if you accept the license. If you do not accept the license, you have no rights under this license.

(9) You are not required to accept this license, since you have not signed it. However, nothing else grants you permission to use, copy, modify, or distribute the Package or its derivative works. These actions are prohibited by law if you do not accept this license. Therefore, by using, copying, modifying, or distributing the Package (or any work based on the Package), you indicate your acceptance of this license to do so, and all its terms and conditions for copying, distributing, or modifying the Package or works based on it.

Termination of the License

(10) This license does not grant you the right to use any trademark, service mark, tradename, or logo of the Copyright Holder.

(11) 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 against any entity (including a cross-claim or counterclaim in a lawsuit) 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.
