উইকিপিডিয়া:মুক্ত নয় এমন উপাদান

উইকিপিডিয়া, মুক্ত বিশ্বকোষ থেকে

উইকিপিডিয়াতে আমাদের আসু উদ্দেশ্য একটি মুক্ত উপাদানযুক্ত বিশ্বকোষ তৈরী করা, যেখানে মুক্ত উপাদান বলতে বোঝানো হয়েছে যেকোন প্রদত্ত বস্তুর উপাদানকে পুনর্বিতরণ,অধ্যয়ন, পরিবর্তন ও উন্নতিসাধন করার অধিকার এবং অন্যভাবে বললে এই কর্মটিকে যেকোন উদ্দেশ্যে, এমনকি বাণিজ্যিকভাবে ব্যবহারকে বোঝায়। কিন্থু, সেহেতু স্বাধীনভাবে কোন কিছুর মূল্য ও মুক্ত মানে স্বাধীন এই দুইটি ভিন্ন বিষয়,সেইহেতু ইন্টারনেটে প্রাপ্ত মুক্ত ছবিগুলি এখনও উইকিপিডিয়ায় ব্যবহার করা যায় না বা যাবে না । যেকোন উপাদান যা বিচারধারাকে পরিতুষ্ঠ করে না,যেমন কেবলমাত্র চিত্রের ক্ষেত্রে " অ-বানিজ্যিক ব্যবহার ",কেবলমাত্র উইকিপিডিয়াতে ব্যবহার করার অনুমতি আছে অথবা সম্পূর্ণভাবে কপিরাইট যুক্ত চিত্রগুলিকে মুক্ত নয় এমন উপাদান হিসাবে শ্রেণীভুক্ত করা হয়।

The Licensing policy of the Wikimedia Foundation requires all content hosted on Wikipedia to be free content. However, there are exceptions. The policy allows projects to adopt an exemption doctrine policy allowing the use of non-free content within strictly defined limitations. There are situations where acquiring a freely licensed image for a particular subject may not be possible; non-free content can be used on Wikipedia in these cases, but only within the doctrine of fair use. The use of non-free images on Wikipedia must fall within purposely stricter standards than defined by copyright law as defined by our non-free content criteria as described below.

Policy[সম্পাদনা]

Yes check.svg The following section of this page is an official policy on Wikipedia. It is considered a standard that all users should follow. Feel free to edit this section as needed, but please make sure that changes you make to this policy reflect consensus before you make them.

Transcluded from Wikipedia:Non-free content criteria; this is the part of the current page that is official policy


For the full non-free content use guideline (including this policy and its criteria) see Wikipedia:Non-free content.
As per the March 23, 2007 Wikimedia Foundation Licensing policy resolution this document serves as the Exemption Doctrine Policy for the English Wikipedia.

Rationale[সম্পাদনা]

  • To support Wikipedia's mission to produce perpetually free content for unlimited distribution, modification and application by all users in all media.
  • To minimize legal exposure by limiting the amount of non-free content, using more narrowly defined criteria than apply under United States fair use law.
  • To facilitate the judicious use of non-free content to support the development of a high-quality encyclopedia.

Policy[সম্পাদনা]

There is no automatic entitlement to use non-free content in an article or elsewhere on Wikipedia. Articles and other Wikipedia pages may, in accordance with the guideline, use brief verbatim textual excerpts from copyrighted media, properly attributed or cited to its original source or author. Other non-free content—including all copyrighted images, audio and video clips, and other media files that lack a free content license—may be used on the English Wikipedia only where all 10 of the following criteria are met.

  1. উইকিপিডিয়া:মুক্ত নয় এমন উপাদান/spanNo free equivalent. Non-free content is used only where no free equivalent is available, or could be created, that would serve the same encyclopedic purpose. Where possible, non-free content is transformed into free material instead of using a fair-use defense, or replaced with a freer alternative if one of acceptable quality is available; "acceptable quality" means a quality sufficient to serve the encyclopedic purpose. (As a quick test, before adding non-free content requiring a rationale, ask yourself: "Can this non-free content be replaced by a free version that has the same effect?" and "Could the subject be adequately conveyed by text without using the non-free content at all?" If the answer to either is yes, the non-free content probably does not meet this criterion.)
  2. উইকিপিডিয়া:মুক্ত নয় এমন উপাদান/spanRespect for commercial opportunities. Non-free content is not used in a manner that is likely to replace the original market role of the original copyrighted media.
  3. উইকিপিডিয়া:মুক্ত নয় এমন উপাদান/span
    1. উইকিপিডিয়া:মুক্ত নয় এমন উপাদান/spanMinimal usage. Multiple items of non-free content are not used if one item can convey equivalent significant information.
    2. উইকিপিডিয়া:মুক্ত নয় এমন উপাদান/spanMinimal extent of use. An entire work is not used if a portion will suffice. Low- rather than high-resolution/fidelity/bit rate is used (especially where the original could be used for deliberate copyright infringement). This rule also applies to the copy in the File: namespace.
  4. উইকিপিডিয়া:মুক্ত নয় এমন উপাদান/spanPrevious publication. Non-free content must have been published or publicly displayed outside Wikipedia.
  5. উইকিপিডিয়া:মুক্ত নয় এমন উপাদান/spanContent. Non-free content meets general Wikipedia content standards and is encyclopedic.
  6. উইকিপিডিয়া:মুক্ত নয় এমন উপাদান/spanMedia-specific policy. The material meets Wikipedia's media-specific policy. For example, images must meet Wikipedia:Image use policy.
  7. উইকিপিডিয়া:মুক্ত নয় এমন উপাদান/spanOne-article minimum. Non-free content is used in at least one article.
  8. উইকিপিডিয়া:মুক্ত নয় এমন উপাদান/spanContextual significance. Non-free content is used only if its presence would significantly increase readers' understanding of the topic, and its omission would be detrimental to that understanding.
  9. উইকিপিডিয়া:মুক্ত নয় এমন উপাদান/spanRestrictions on location. Non-free content is allowed only in articles (not disambiguation pages), and only in article namespace, subject to exemptions. (To prevent an image category from displaying thumbnails, add __NOGALLERY__ to it; images are linked, not inlined, from talk pages when they are a topic of discussion.)
  10. উইকিপিডিয়া:মুক্ত নয় এমন উপাদান/spanImage description page. The image or media description page contains the following:
    1. উইকিপিডিয়া:মুক্ত নয় এমন উপাদান/spanIdentification of the source of the material, supplemented, where possible, with information about the artist, publisher and copyright holder; this is to help determine the material's potential market value. See: Wikipedia:Citing sources#When uploading an image.
    2. A copyright tag that indicates which Wikipedia policy provision is claimed to permit the use. For a list of image copyright tags, see Wikipedia:Image copyright tags/Non-free content.
    3. উইকিপিডিয়া:মুক্ত নয় এমন উপাদান/spanThe name of each article (a link to each article is also recommended) in which fair use is claimed for the item, and a separate, specific fair-use rationale for each use of the item, as explained at Wikipedia:Non-free use rationale guideline. The rationale is presented in clear, plain language and is relevant to each use.

Enforcement[সম্পাদনা]

  • A file with a valid non-free-use rationale for some (but not all) articles it is used in will not be deleted. Instead, the file should be removed from the articles for which it lacks a non-free-use rationale, or a suitable rationale added.
  • A file on which non-free use is claimed that is used in no article (criterion 7) may be deleted seven days after notification.
  • A file in use in an article and uploaded after 13 July 2006 that does not comply with this policy 48 hours after notification to the uploading editor will be deleted. To avoid deletion, the uploading editor or another Wikipedian will need to provide a convincing non-free-use defense that satisfies all 10 criteria. For a file in use in an article that was uploaded before 13 July 2006, the 48-hour period is extended to seven days.
    • Note that it is the duty of users seeking to include or retain content to provide a valid rationale; those seeking to remove or delete it are not required to show that one cannot be created—see burden of proof.

Deletion criteria for non-free content are specified in Wikipedia:Criteria for speedy deletion.

Guideline examples[সম্পাদনা]

Non-free content that meets all of the policy criteria above but does not fall under one of the designated categories below may or may not be allowable, depending on what the material is and how it is used. These examples are not meant to be exhaustive, and depending on the situation there are exceptions. When in doubt as to whether non-free content may be included, please make a judgement based on the spirit of the policy, not necessarily the exact wording. If you want help in assessing whether a use is acceptable, please ask at Wikipedia:Media copyright questions. Wikipedia talk:Copyrights, Wikipedia talk:Copyright problems, and Wikipedia talk:Non-free content may also be useful. These are places where those who understand copyright law and Wikipedia policy are likely to be watching.

See also: Wikipedia:Wikipedia Signpost/2008-09-22/Dispatches, a guide to evaluating the acceptability of non-free images.

Acceptable use[সম্পাদনা]

Text[সম্পাদনা]

Brief quotations of copyrighted text may be used to illustrate a point, establish context, or attribute a point of view or idea. Copyrighted text that is used verbatim must be attributed with quotation marks or other standard notation, such as block quotes. Any alterations must be clearly marked, i.e. [brackets] for added text, an ellipsis (...) for removed text, and emphasis noted after the quotation as "(emphasis added)" or "(emphasis in the original)". Extensive quotation of copyrighted text is prohibited.

Audio clips[সম্পাদনা]

  1. Music clips may be used to identify a musical style, group, or iconic piece of music when accompanied by appropriate sourced commentary and attributed to the copyright holder. Samples should generally not be longer than 30 seconds or 10% of the length of the original song, whichever is shorter (see Wikipedia:Music samples).
  2. Spoken word clips of historical events, such as speeches by public figures, may be used when accompanied by appropriate sourced commentary and attributed to the speaker/author.
  3. For further information, see Wikipedia:Music samples.

Images[সম্পাদনা]

সংক্ষিপ্ত:

Some copyrighted images may be used on Wikipedia, providing they meet both the legal criteria for fair use, and Wikipedia's own guidelines for non-free content. Copyrighted images that reasonably can be replaced by free/libre images are not suitable for Wikipedia.

  1. Cover art: Cover art from various items, for identification only in the context of critical commentary of that item (not for identification without critical commentary).
  2. Team and corporate logos: For identification. See Wikipedia:Logos.
  3. Stamps and currency: For identification of the stamp or currency, not its subject.
  4. Other promotional material: Posters, programs, billboards, ads. For critical commentary.
  5. Film and television screen shots: For critical commentary and discussion of the cinema and television.
  6. Screenshots from software products: For critical commentary.
  7. Paintings and other works of visual art: For critical commentary, including images illustrative of a particular technique or school.
  8. Images with iconic status or historical importance: As subjects of commentary.

Unacceptable use[সম্পাদনা]

Text[সম্পাদনা]

  1. Unattributed pieces of text from a copyrighted source.
  2. Excessively long copyrighted excerpts.
  3. An image of a newspaper article or other publication that contains long legible sections of copyrighted text. If the text is important as a source or quotation, it should be worked into the article in text form with the article cited as a source.
  4. All copyrighted text poses legal problems when making spoken word audio files from Wikipedia articles, and should be avoided in such files, because the resulting audio file cannot be licensed under the GFDL.

Multimedia[সম্পাদনা]

  1. Excessive quantities of short audio clips in a single article. A smaller number may be appropriate if each is accompanied by commentary in the accompanying text.
  2. A long audio excerpt, to illustrate a stylistic feature of a contemporary band; see above for acceptable limits.
  3. A short video excerpt from a contemporary film, without sourced commentary in the accompanying text.

The use of non-free media (whether images, audio or video clips) in galleries, discographies, and navigational and user-interface elements generally fails the test for significance (criterion #8).

Images[সম্পাদনা]

সংক্ষিপ্ত:
  1. An album cover as part of a discography, as per the above.
  2. A rose, cropped from a record album, to illustrate an article on roses.
  3. A map, scanned or traced from an atlas, to illustrate the region depicted. Use may be appropriate if the map itself is a proper subject for commentary in the article: for example, a controversial map of a disputed territory, if the controversy is discussed in the article.
  4. An image whose subject happens to be a war, to illustrate an article on the war. Use may be appropriate if the image itself is a proper subject for commentary in the article: for example, an iconic image that has received attention in its own right, if the image is discussed in the article.
  5. An image to illustrate an article passage about the image, if the image has its own article (in which case the image may be described and a link provided to the article about the image)
  6. A photo from a press agency (e.g., AP), unless the photo itself is the subject of sourced commentary in the article.
  7. A Barry Bonds baseball card, to illustrate the article on Barry Bonds. The use may be appropriate to illustrate a passage on the card itself; see the Billy Ripken article.
  8. A magazine or book cover, to illustrate the article on the person whose photograph is on the cover. However, if the cover itself is the subject of sourced discussion in the article, it may be appropriate if placed inline next to the commentary. Similarly, a photo of a copyrighted statue (and there is no freedom of panorama in the country where the statue is) can only be used to discuss the statue itself, not the subject of it.
  9. An image with an unknown or unverifiable origin. This does not apply to historical images, where sometimes only secondary sources are known, as the ultimate source of some historical images may never be known with certainty.
  10. A chart or graph. These can almost always be recreated from the original data.
  11. A commercial photograph reproduced in high enough resolution to potentially undermine the ability of the copyright holder to profit from the work.
সংক্ষিপ্ত:

Pictures of people still alive, groups still active, and buildings still standing; provided that taking a new free picture as a replacement (which is almost always considered possible) would serve the same encyclopedic purpose as the non-free image. This includes non-free promotional images.

  1. However, for some retired or disbanded groups, or retired individuals whose notability rests in large part on their earlier visual appearance, a new picture may not serve the same purpose as an image taken during their career, in which case the use would be acceptable.

Non-free image use in list articles[সম্পাদনা]

সংক্ষিপ্ত:

In articles and sections of articles that consist of several small sections of information for a series of elements common to a topic, such as a list of characters in a fictional work, non-free images should be used judiciously to present the key visual aspects of the topic. It is inadvisable to provide a non-free image for each entry in such an article or section. The following considerations should be made to reduce the number of new non-free images associated with such lists:

  1. Images that show multiple elements of the list at the same time, such as a cast shot or montage for a television show, are strongly preferred over individual images. Such an image should be provided by the copyright holder or scanned/captured directly from the copyrighted work, instead of being created from multiple non-free images by the user directly (as the "extent" of use is determined by the number and resolution of non-free images, and not the number of files.)
  2. Images which are discussed in detail in the context of the article body, such as a discussion of the art style, or a contentious element of the work, are preferable to those that simply provide visual identification of the elements.
  3. An image that provides a representative visual reference for other elements in the article, such as what an alien race may look like on a science-fiction television show, is preferred over providing a picture of each element discussed.
  4. If another non-free image of an element of an article is used elsewhere within Wikipedia, either referring to its other use or, more preferably, repeating its use on the list are strongly preferred over including a new, separate, non-free image. If duplicating the use of a non-free image, please be aware that a separate non-free fair use rationale must be supplied for the image for the new use.
  5. For media that involves live actors, do not supply an image of the actor in their role if an appropriate free image of the actor exists on their page (as per WP:BLP and above), if there is little difference in appearance between actor and role. However, if there is a significant difference due to age or makeup and costuming, then, when needed, it may be appropriate to include a non-free image to demonstrate the role of the actor in that media.
  6. Barring the above, images that are used only to visually identify elements in the article should be used as sparingly as possible. Consider restricting such uses to major characters and elements or those that cannot be described easily in text, as agreed to by editor consensus.

Non-free image use in galleries[সম্পাদনা]

সংক্ষিপ্ত:

The use of non-free images arranged in a gallery or tabular format is usually unacceptable, but should be considered on a case-by-case basis. Exceptions should be very well-justified and alternate forms of presentation (including with fewer images) strongly considered.

In categories that include non-free content, MediaWiki's __NOGALLERY__ code should be used to disable the display of the content while still listing it.

Exemptions[সম্পাদনা]

Exemptions from non-free content policy are made for the use of non-free content on certain administrative, non-article space pages as necessary to creating or managing the encyclopedia, specifically for those that are used to manage questionable non-free content. Those pages that are exempt are listed in Category:Wikipedia non-free content criteria exemptions.

Implementation and enforcement[সম্পাদনা]

Non-free images need a copyright tag, source information, and use rationales. We have various copyright tag templates. Be sure to describe the source from which the image was obtained. A separate use rationale must be written each time the image is used in an article, specific to that particular use. All of these go in the image description page at the time the image file is uploaded.

Explanation of policy and guidelines[সম্পাদনা]

Background[সম্পাদনা]

"Free" content is defined as that which meets the "Definition of Free Cultural Works".

Material that is not free is permitted only if it meets the restrictions of this policy. This has been explicitly declared since May 2005.[১] The stated mission of the Wikimedia Foundation, which runs Wikipedia, is "to empower and engage people around the world to collect and develop educational content under a free license or in the public domain, and to disseminate it effectively and globally." These concerns are embodied in the above requirements that all non-free content must meet, and our policy of deleting non-compliant content. Being generous to the world sometimes means being hard on ourselves. Please understand that these rules are not arbitrary; they are central to our mission.

Wikipedia distributes content throughout the world with no restrictions on how people use it. Legally, we could use any copyrighted material for ourselves that is either licensed to us by the owner, or that fits the definition of "fair use" under US copyright law. However, we favor content that everyone can use, not just Wikipedia. We want them to be free to use, redistribute, or modify the content, for any purpose, without significant legal restrictions, particularly those of copyright.

To honor its mission, Wikipedia accepts incoming copyright licenses only if they meet Wikipedia's definition of "free" use. This is a higher standard than we would need just for our own use. But our ability to use a work does not guarantee that others may use it. We reject licenses that limit use exclusively to Wikipedia or for non-commercial purposes. Commercial use is a complex issue that goes well beyond a company's for-profit status, another reason to be careful. In fact, we reject any licenses with significant limitations. That is not free enough.

Similarly, Wikipedia imposes higher fair-use standards on itself than US copyright law. There are some works, such as important photographs, significant modern artworks, that we cannot realistically expect to be released under a free content license, but that are hard to discuss in an educational context without including examples from the media itself. In other cases such as cover art / product packaging, a non-free work is needed to discuss a related subject. This policy allows such material to be used if it meet U.S. legal tests for fair use, but we impose additional limitations. Just because something is "fair use" on a Wikipedia article in the US does not mean it is fair use in another context. A downstream user's commercial use of content in a commercial setting may be illegal even if our noncommercial use is legal. Use in another country with different fair use and fair dealing laws may be illegal as well. That would fail our mission. We therefore limit the media content we offer, to make sure what we do offer has the widest possible legal distribution.

We do not want downstream re-users to rely solely on our assurances. They are liable for their own actions, no matter what we tell them. We therefore show them and let them make their own decision. To that end we require a copyright tag describing the nature of a copyrighted work, sourcing material saying exactly where any non-free content comes from, and a detailed non-free media rationale for every use of copyrighted content in every article, justifying why use in that article is permitted.

A further goal of minimizing licensed and fair-use material is to encourage creation of original new content, rather than relying on borrowed content that comes with restrictions.

Legal position[সম্পাদনা]

In general[সম্পাদনা]

Under United States copyright law, creative works published in the United States prior to 1923 are in the public domain. Some creative works published in the United States between 1923 and 1963 are still copyrighted. It is illegal (among other things) to reproduce or make derivative works of copyrighted works without legal justification.[২] Unless a thorough search is conducted to determine that a copyright has expired or not been renewed, it should be regarded as copyrighted.[৩]

Certain works have no copyright at all. Most material published in the United States before 1923, works published before 1978 without a copyright notice, with an expired copyright term, or produced by the US federal government, among others, is public domain, i.e. has no copyright. Some such as photos and scans of 2-dimensional objects and other "slavish reproductions", short text phrases, typographic logos, and product designs, do not have a sufficient degree of creativity apart from their functional aspects to have a copyright.

Copyright law only governs creative expressions that are "fixed in a tangible medium of expression," not the ideas or information behind the works. It is legal to reformulate ideas based on written texts, or create images or recordings inspired by others, as long as there is no copying (see plagiarism for how much reformulation is necessary).

If material does have a copyright, it may only be copied or distributed under a license (permission) from the copyright holder, or under the doctrine of fair use. If there is a valid license, the user must stay within the scope of the license (which may include limitations on amount of use, geographic or business territory, time period, nature of use, etc.). Fair use, by contrast, is a limited right to use copyrighted works without permission, highly dependent on the specific circumstances of the work and the use in question. It is a doctrine incorporated as a clause in United States copyright code, arising out of a concern that strict application of copyright law would limit criticism, commentary, scholarship, and other important free speech rights. A comparable concept of fair dealing exists in some other countries, where standards may vary.

Any materials that were published in other nations, and which are copyrighted under the laws of that nation, should be considered to be copyrighted in the United States under the URAA.

Applied to Wikipedia[সম্পাদনা]

Never use materials that infringe the copyrights of others. This could create legal liabilities and seriously hurt the project.

Uploading an image file, audio or video file, or text quotation into Wikipedia, and adding that file to a project page, both raise copyright concerns. Editors who do either must make sure their contributions are legal. If there is any doubt as to legality, ask others for help, try to find a free equivalent, or use your own words to make the same point. Also, consider asking the copyright holder to release the work under an appropriate GFDL license. See Wikipedia:Boilerplate request for permission for a sample form letter.

If a work has no copyright or is licensed to Wikipedia under an acceptable "free" license, it is a free work and may be used on Wikipedia without copyright concerns. See public domain, copyright, and Cornell University's guide to copyright terms for discussion of works that are not covered by copyright. Also see free license regarding free licenses and Wikipedia:Image copyright tags/Free licenses for a list of copyright tags for these works. Restricted licenses to these works offer some legal rights, but Wikipedia ignores them because they are not free enough for its purposes. Instead, works covered by inadequate licenses are treated the same on Wikipedia as works with no licenses at all.

If a work is not free, Wikipedia requires that it comply with Wikipedia's non-free use policy. As explained above, this policy is more restrictive than US law requires. Logically, material that satisfies the policy should also satisfy legal requirements as well. However, to be more certain of avoiding legal liability, and to understand the meaning of Wikipedia policy, editors should consider the legal rules as well. See fair use for further information, and the Stanford University summary of relevant cases, on the subject of fair use.

Non-free material is used only if, in addition to other restrictions, we firmly believe that the use would be deemed fair use if we were taken to court. The Wikimedia Foundation reserves the right to remove unfree copyrighted content at any time. Note that citation sources and external links raise other copyright concerns that are addressed in other policies.

Other Wikimedia projects[সম্পাদনা]

This policy is specific to the English language Wikipedia. Other Wikimedia projects, including Wikipedias in other languages, may have different policies on non-free content. As of November 2008, 28 out of 52 Wikimedia projects do not allow any fair use. A list of projects and their policies on fair use can be read at Wikimedia Meta-wiki. Specific information about different language versions of Wikipedia and their rules on fair use can also been seen at Meta.
