Creative Commons license

(Redirected fromCreative Commons License)
This article is about the Creative Commons licenses. For the organization that produced them, seeCreative Commons.

ACreative Commons(CC)licenseis one of severalpublic copyright licensesthat enable the free distribution of an otherwisecopyrighted"work".[a]A CC license is used when an author wants to give other people the right to share, use, and build upon a work that the author has created. CC provides an author flexibility (for example, they might choose to allow only non-commercial uses of a given work) and protects the people who use or redistribute an author's work from concerns of copyright infringement as long as they abide by the conditions that are specified in the license by which the author distributes the work.[1][2][3][4][5]

There are several types of Creative Commons licenses. Each license differs by several combinations that condition the terms of distribution. They were initially released on December 16, 2002, byCreative Commons,a U.S.non-profitcorporation founded in 2001. There have also been five versions of the suite of licenses, numbered 1.0 through 4.0.[6]Released in November 2013, the 4.0 license suite is the most current. While the Creative Commons license was originally grounded in the American legal system, there are now severalCreative Commons jurisdiction portswhich accommodate international laws.[7][8]

In October 2014, theOpen Knowledge Foundationapproved the Creative Commons CC BY, CC BY-SA and CC0 licenses as conformant with the "Open Definition"for content and data.[9][10][11]

History

edit
Aaron Swartzand Lawrence Lessig at the 2002 event for the first release of the licenses

Lawrence LessigandEric Eldreddesigned the Creative Commons License (CCL) in 2001 because they saw a need for a license between the existing modes of copyright andpublic domainstatus. Version 1.0 of the licenses was officially released on 16 December 2002.[12]

Origins

edit

The CCL allows inventors to keep the rights to their innovations while also allowing for some external use of the invention.[13]The CCL emerged as a reaction to the decision inEldred v. Ashcroft,in which theUnited States Supreme Courtruled constitutional provisions of theCopyright Term Extension Actthat extended the copyright term of works to be the last living author's lifespan plus an additional 70 years.[13]

License porting

edit

The original non-localized Creative Commons licenses were written with the U.S. legal system in mind; therefore, the wording may be incompatible with local legislation in otherjurisdictions,rendering the licenses unenforceable there. To address this issue, Creative Commons asked its affiliates to translate the various licenses to reflect local laws in a process called "porting".[14]As of July 2011, Creative Commons licenses have been ported to over 50 jurisdictions worldwide.[15]

International use

edit

Chinese use

edit

Working with Creative Commons, the Chinese government adapted the Creative Commons License to the Chinese context, replacing the individual monetary compensation of U.S. copyright law with incentives to Chinese innovators to innovate as a social contribution.[16]

Applicable works

edit

Thesecond versionof theMayer and Bettlepromotional animation explaining Creative Commons withJamendoas an example

Work licensed under a Creative Commons license is governed by applicable copyright law.[17]This allows Creative Commons licenses to be applied to all work falling under copyright, including: books, plays, movies, music, articles, photographs, blogs, and websites.

Software

edit

Whilesoftwareis also governed by copyright law and CC licenses are applicable, the CC recommends against using it in software specifically due to backward-compatibility limitations with existing commonly used software licenses.[18][19]Instead, developers may resort to use more software-friendlyfree and open-source software(FOSS)software licenses.Outside the FOSS licensing use case for software there areseveral usage examplesto utilize CC licenses to specify a "Freeware"license model; examples areThe White Chamber,Mari0orAssault Cube.[20]Despite the status of CC0 as the most free copyright license, theFree Software Foundationdoes not recommend releasingsoftware into the public domainusing the CC0 due to patent concerns.[21]

However, application of a Creative Commons license may not modify the rights allowed byfair useor fair dealing or exert restrictions which violate copyright exceptions.[22]Furthermore, Creative Commons licenses are non-exclusive and non-revocable.[23]Any work or copies of the work obtained under a Creative Commons license may continue to be used under that license.[24]

When works are protected by more than one Creative Commons license, the user may choose any of them.[25]

Preconditions

edit

The author, or the licensor in case the author did a contractual transfer of rights, needs to have the exclusive rights on the work. If the work has already been published under a public license, it can be uploaded by any third party, once more on another platform, by using a compatible license, and making reference and attribution to the original license (e.g. by referring to the URL of the original license).[26]

Consequences

edit

The license is non-exclusive, royalty-free, and unrestricted in terms of territory and duration, so it is irrevocable, unless a new license is granted by the author after the work has been significantly modified. Any use of the work that is not covered by other copyright rules triggers the public license. Upon activation of the license, the licensee must adhere to all conditions of the license, otherwise the license agreement is illegitimate, and the licensee would commit a copyright infringement. The author, or the licensor as a proxy, has the legal rights to act upon any copyright infringement. The licensee has a limited period to correct any non-compliance.[26]

Four rights

edit

The CC licenses all grant "baseline rights", such as the right to distribute the copyrighted work worldwide for non-commercial purposes and without modification.[27]In addition, different versions of license prescribe different rights, as shown in this table:[28]

Icon Right Description
Attribution(BY) Licensees may copy, distribute, display, perform and make derivative works and remixes based on it only if they give the author or licensor the credits (attribution) in the manner specified by these. Since version 2.0, all Creative Commons licenses require attribution to the creator and include the BY element. The letters BY are not an abbreviation, unlike the other rights.
Share-alike(SA) Licensees may distribute derivative works only under a license identical to ( "not more restrictive than" ) the license that governs the original work. (See alsoCopyleft.) Without share-alike, derivative works might be sublicensed with compatible but more restrictive license clauses, e.g. CC BY to CC BY-NC.
Non-commercial(NC) Licensees may copy, distribute, display, perform the work and make derivative works and remixes based on it only fornon-commercialpurposes.
Noderivative works(ND) Licensees may copy, distribute, display and perform only verbatim copies of the work, notderivative worksandremixesbased on it. Since version 4.0, derivative works are allowed but must not be shared.

The last two clauses are notfree contentlicenses, according to definitions such asDFSGor theFree Software Foundation's standards, and cannot be used in contexts that require these freedoms, such asWikipedia.Forsoftware,Creative Commons includes three free licenses created by other institutions: theBSD License,the GNULGPL,and the GNUGPL.[29]

Mixing and matching these conditions produces sixteen possible combinations, of which eleven are valid Creative Commons licenses and five are not. Of the five invalid combinations, four include both the "ND" and "SA" clauses, which are mutually exclusive; and one includes none of the clauses. Of the eleven valid combinations, the five that lack the "BY" clause have been retired because 98% of licensors requested attribution, though they do remain available for reference on the website.[30][31][32]This leaves six regularly used licenses plus the CC0public domaindeclaration.

Six regularly used licenses

edit

The six licenses in most frequent use are shown in the following table. Among them, those accepted by the Wikimedia Foundation – the public domain dedication and two attribution (BY and BY-SA) licenses – allow the sharing and remixing (creatingderivative works), including for commercial use, so long as attribution is given.[32][33][34]

Creative CommonsPublic Domain Mark.Indicates works which have already fallen into (or were given to) the public domain.

Besides copyright licenses, Creative Commons also offersCC0,a tool for relinquishing copyright and releasing material into thepublic domain.[34]CC0 is a legal tool forwaivingas many rights as legally possible.[36]Or, when not legally possible, CC0 acts as fallback aspublic domain equivalent license.[36]Development of CC0 began in 2007[37]and it was released in 2009.[38][39]A major target of the license was the scientific data community.[40]

In 2010, Creative Commons announced itsPublic Domain Mark,[41]a tool for labeling works already in the public domain. Together, CC0 and the Public Domain Mark replace the Public Domain Dedication and Certification,[42]which took a U.S.-centric approach and co-mingled distinct operations.

In 2011, theFree Software Foundationadded CC0 to itsfree software licenses.However, the Free Software Foundation currently does not recommend using CC0 to releasesoftware into the public domainbecause it explicitly does not grant a patent license.[21]

In February 2012, CC0 was submitted toOpen Source Initiative(OSI) for their approval.[43]However, controversy arose over its clause which excluded from the scope of the license any relevant patents held by the copyright holder. This clause was added for scientific data rather than software, but some members of the OSI believed it could weaken users' defenses againstsoftware patents.As a result, Creative Commons withdrew their submission, and the license is not currently approved by the OSI.[40][44]

From 2013 to 2017, thestock photographywebsiteUnsplashused the CC0 license,[45][46]distributing several million free photos a month.[47]Lawrence Lessig,the founder of Creative Commons, has contributed to the site.[48]Unsplash moved from using the CC0 license to a custom license in June 2017[49]and to an explicitlynonfreelicense in January 2018.

In October 2014, theOpen Knowledge Foundationapproved the Creative Commons CC0 as conformant with theOpen Definitionand recommend the license to dedicate content to the public domain.[10][11]

In July 2022Fedora Linuxdisallowed software licensed under CC0 due to patent rights explicitly not being waived under the license.[50]

Retired licenses

edit

Due to either disuse or criticism, a number of previously offered Creative Commons licenses have since been retired,[30][51]and are no longer recommended for new works. The retired licenses include all licenses lacking the Attribution element other than CC0, as well as the following four licenses:

  • Developing Nations License:a license which only applies todeveloping countriesdeemed to be "non-high-income economies" by theWorld Bank.Full copyright restrictions apply to people in other countries.[52]
  • Sampling:parts of the work can be used for any purpose other than advertising, but the whole work cannot be copied or modified[53]
  • Sampling Plus:parts of the work can be copied and modified for any purpose other than advertising, and the entire work can be copied for noncommercial purposes[54]
  • NonCommercial Sampling Plus:the whole work or parts of the work can be copied and modified for non-commercial purposes[55]

Version 4.0

edit
Main article:Creative Commons jurisdiction ports

The latest version 4.0 of the Creative Commons licenses, released on November 25, 2013, are generic licenses that are applicable to most jurisdictions and do not usually require ports.[56][57][58][28]No new ports have been implemented in version 4.0 of the license.[59]Version 4.0 discourages using ported versions and instead acts as a single global license.[60]

Rights and obligations

edit

Attribution

edit

Since 2004, all current licenses other than the CC0 variant require attribution of the original author, as signified by the BY component (as in the preposition "by" ).[31]The attribution must be given to "the best of [one's] ability using the information available".[61]Creative Commons suggests the mnemonic "TASL":title–author – source[web link] – [CC]licence.
Generally this implies the following:

  • Include any copyright notices (if applicable).If the work itself contains any copyright notices placed there by the copyright holder, those notices must be left intact, or reproduced in a way that is reasonable to the medium in which the work is being re-published.
  • Cite the author's name, screen name, or user ID,etc. If the work is being published on the Internet, it is nice to link that name to the person's profile page, if such a page exists.
  • Cite the work's title or name (if applicable),if such a thing exists. If the work is being published on the Internet, it is nice to link the name or title directly to the original work.
  • Cite the specific CC license the work is under.If the work is being published on the Internet, it is nice if the license citation links to the license on the CC website.
  • Mention if the work is a derivative work or adaptation.In addition to the above, one needs to identify that their work is a derivative work, e.g., "This is a Finnish translation of [original work] by [author]." or "Screenplay based on [original work] by [author]."

Non-commercial licenses

edit
Main article:Creative Commons NonCommercial license

The NonCommercial license allows image creators to restrict selling and profiting from their works by other parties and thus maintaining free of charge access to images.

The "non-commercial" option included in some Creative Commons licenses is controversial in definition,[62]as it is sometimes unclear what can be considered a non-commercial setting, and application, since its restrictions differ from the principles ofopen contentpromoted by otherpermissive licenses.[63]In 2014Wikimedia Deutschlandpublished a guide to using Creative Commons licenses aswiki pagesfor translations and as PDF.[26]

Adaptability

edit
An example of a permitted combination of two works, one being CC BY-SA and the other being public domain

Rights in an adaptation can be expressed by a CC license that is compatible with the status or licensing of the original work or works on which the adaptation is based.[64]

License compatibilitychart for combining or mixing two CC licensed works[65][66]






edit

The legal implications of large numbers of works having Creative Commons licensing are difficult to predict, and there is speculation that media creators often lack insight to be able to choose the license which best meets their intent in applying it.[67]

Some works licensed using Creative Commons licenses have been involved in several court cases.[68]Creative Commons itself was not a party to any of these cases; they only involved licensors or licensees of Creative Commons licenses. When the cases went as far as decisions by judges (that is, they were not dismissed for lack of jurisdiction or were not settled privately out of court), they have all validated the legal robustness of Creative Commons public licenses.

Dutch tabloid

edit

In early 2006, podcasterAdam Currysued a Dutch tabloid who published photos from Curry's Flickr page without Curry's permission. The photos were licensed under the Creative Commons Non-Commercial license. While the verdict was in favor of Curry, the tabloid avoided having to pay restitution to him as long as they did not repeat the offense. Professor Bernt Hugenholtz, main creator of the Dutch CC license and director of the Institute for Information Law of the University of Amsterdam, commented, "The Dutch Court's decision is especially noteworthy because it confirms that the conditions of a Creative Commons license automatically apply to the content licensed under it, and binds users of such content even without expressly agreeing to, or having knowledge of, the conditions of the license."[69][70][71][72]

Virgin Mobile

edit

In 2007,Virgin Mobile Australialaunched an advertising campaign promoting their cellphone text messaging service using the work of amateur photographers who uploaded their work toFlickrusing a Creative Commons-BY (Attribution) license. Users licensing their images this way freed their work for use by any other entity, as long as the original creator was attributed credit, without any other compensation required. Virgin upheld this single restriction by printing a URL leading to the photographer's Flickr page on each of their ads. However, one picture, depicting 15-year-old Alison Chang at a fund-raising carwash for her church,[73]caused some controversy when she sued Virgin Mobile. The photo was taken by Alison's church youth counselor, Justin Ho-Wee Wong, who uploaded the image to Flickr under the Creative Commons license.[73]In 2008, the case (concerningpersonality rightsrather than copyright as such) was thrown out of a Texas court for lack of jurisdiction.[74][75]

SGAE vs Fernández

edit

In the fall of 2006, thecollecting societySociedad General de Autores y Editores(SGAE) in Spain sued Ricardo Andrés Utrera Fernández, owner of a disco bar located inBadajozwho played CC-licensed music. SGAE argued that Fernández should pay royalties for public performance of the music between November 2002 and August 2005. The Lower Court rejected the collecting society's claims because the owner of the bar proved that the music he was using was not managed by the society.[76]

In February 2006, the Cultural Association Ladinamo (based in Madrid, and represented byJavier de la Cueva) was granted the use of copyleft music in their public activities. The sentence said:

Admitting the existence of music equipment, a joint evaluation of the evidence practiced, this court is convinced that the defendant prevents communication of works whose management is entrusted to the plaintiff [SGAE], using a repertoire of authors who have not assigned the exploitation of their rights to the SGAE, having at its disposal a database for that purpose and so it is manifested both by the legal representative of the Association and by Manuela Villa Acosta, in charge of the cultural programming of the association, which is compatible with the alternative character of the Association and its integration in the movement called 'copy left'.[77]

GateHouse Media, Inc. v. That's Great News, LLC

edit

On June 30, 2010,GateHouse Mediafiled a lawsuit against That is Great News. GateHouse Media owns a number of local newspapers, includingRockford Register Star,which is based in Rockford, Illinois. That is Great News makes plaques out of newspaper articles and sells them to the people featured in the articles.[78]GateHouse sued That is Great News for copyright infringement and breach of contract. GateHouse claimed that TGN violated the non-commercial and no-derivative works restrictions on GateHouse Creative Commons licensed work when TGN published the material on its website. The case was settled on August 17, 2010, though the settlement was not made public.[78][79]

Drauglis v. Kappa Map Group, LLC

edit

In 2007, photographer Art Drauglis uploaded several pictures to the photo-sharing website Flickr, giving them the Creative Commons Attribution-ShareAlike 2.0 Generic License (CC BY-SA). One photo, titled "Swain's Lock, Montgomery Co., MD.", was downloaded by Kappa Map Group, a map-making company, and published in 2012 on the front cover ofMontgomery Co. Maryland Street Atlas.The text "Photo: Swain's Lock, Montgomery Co., MD Photographer: Carly Lesser & Art Drauglis, Creative Commoms [sic], CC-BY-SA-2.0 "was placed on the back cover, but nothing on the front indicated authorship.

The validity of the CC BY-SA 2.0 as a license was not in dispute. The CC BY-SA 2.0 requires that the licensee to use nothing less restrictive than the CC BY-SA 2.0 terms. The atlas was sold commercially and not for free reuse by others. The dispute was whether Drauglis' license terms that would apply to "derivative works" applied to the entire atlas. Drauglis sued the defendants in June 2014 for copyright infringement and license breach, seeking declaratory and injunctive relief, damages, fees, and costs. Drauglis asserted, among other things, that Kappa Map Group "exceeded the scope of the License because defendant did not publish the Atlas under a license with the same or similar terms as those under which the Photograph was originally licensed."[80]The judge dismissed the case on that count, ruling that the atlas was not aderivative workof the photograph in the sense of the license, but rather acollective work.Since the atlas was not a derivative work of the photograph, Kappa Map Group did not need to license the entire atlas under the CC BY-SA 2.0 license. The judge also determined that the work had been properly attributed.[81]

In particular, the judge determined that it was sufficient to credit the author of the photo as prominently as authors of similar authorship (such as the authors of individual maps contained in the book) and that the name "CC-BY-SA-2.0" is sufficiently precise to locate the correct license on the internet and can be considered a valid identifier for the license.[3]

Verband zum Schutz geistigen Eigentums im Internet (VGSE)

edit

In July 2016, German computer magazineLinuxUserreported that a German blogger Christoph Langner used twoCC BY-licensed photographs from Berlin photographer Dennis Skley on his private blog Linuxundich. Langner duly mentioned the author and the license and added a link to the original. Langner was later contacted by theVerband zum Schutz geistigen Eigentums im Internet(VGSE) (Association for the Protection of Intellectual Property in the Internet) with a demand for €2300 for failing to provide the full name of the work, the full name of the author, the license text, and a source link, as is required by the fine print in the license. Of this sum, €40 goes to the photographer, and the remainder is retained by VGSE.[82][83]The Higher Regional Court of Cologne dismissed the claim in May 2019.[84]
