Molte opere creative sono "opere derivate" da qualcos'altro, con un proprio copyright. Un lavoro derivato è un lavoro che non si basa solo su un lavoro precedente, ma che contiene anche sufficiente contenuto nuovo/creativo affinché gli sia attribuito un proprio copyright. Tuttavia, se il lavoro precedente è ancora protetto da diritto d'autore, il detentore del copyright originale deve "anche" licenziare il lavoro originale per il riutilizzo o autorizzare la pubblicazione del lavoro derivato.
In altre parole, un lavoro derivato non è semplicemente un lavoro che è "basato su" un altro lavoro, ma è considerato un "nuovo lavoro" per l'apporto di elementi creativi inediti che include - tutti i lavori derivati basati su un altro lavoro precedente che sono privi di sostanziali nuovi contenuti creativi, sono semplicemente considerati "copie" di quell'opera e non hanno diritto a nessuna nuovo copyright (e non dovrebbero essere indicati come "opere derivate").
Quindi, a meno che il lavoro originale sia di pubblico dominio o che ci siano prove che sia stato pubblicato con una licenza che ne permetta il riutilizzo (ad esempio, con un'appropriata licenza Creative Commons), il creatore dell'opera originale deve autorizzare esplicitamente il lavoro derivato prima che possa essere caricato su Commons.
Questo implica che non si può riprodurre un disegno creativo protetto da copyright fatto da qualcun altro e caricarlo su Commons con una nuova licenza libera perché è una copia fotografica senza contenuto creativo aggiuntivo e quindi il copyright continua ad appartenere all'autore del disegno. Allo stesso modo, non puoi creare una versione cinematografica di un libro che hai appena letto senza il permesso dell'autore del libro, anche se hai aggiunto materiale creativo sostanziale alla trama, perché il film richiede il permesso dello scrittore, dato che la trama ed i personaggi sono frutto della sua creatività. "Derivata", in questo senso, non significa semplicemente "derivato da", significa "derivato da e con nuovi contenuti creativi che hanno diritto a un nuovo copyright".
Cos'è un'opera derivata?
- "Un'opera derivata è un lavoro basato su una o più opere preesistenti, come una traduzione, un arrangiamento musicale, una versione cinematografica, una registrazione sonora, una riproduzione artistica, un riassunto, una condensazione, o qualsiasi altra forma nella quale un lavoro possa essere modificato, trasformato o adattato. Un lavoro consistente in revisioni editoriali, annotazioni, elaborazioni o altre modifiche che, come un tutto, rappresentino il lavoro originale di autore, è un'opera derivata"
Per farla breve, tutti i trasferimenti di un lavoro creativo e sottomesso a copyright verso un nuovo medium (es: da un libro ad un film), così come tutte le altre possibili modifiche di un'opera che producono un nuovo lavoro dal contenuto creativo originale (es: da una pièce di Shakespeare ad un suo adattamento moderno), sono considerate opere derivate con dei nuovi diritti. Chi è autorizzato a realizzare tali opere? Secondo il U.S. Copyright Act of 1976, Section 106:
- "Il detentore dei diritti d'autore ha i diritti esclusivi per realizzare o autorizzare chiunque a: (...) (2) preparare opere derivate basate sul lavoro protetto dai diritti d'autore."
Unlike an exact copy or minor variation of a work (e.g. the same book with a different title), which would be considered a mere copy and would not result in a new copyright, a derivative work creates a new copyright on all original aspects of the new version. Thus, for example, the creator of The Annotated Hobbit holds a copyright on all of the notes and commentary he wrote, but not on the original text of The Hobbit, which is also included in the book, the copyright to which is owned by the Tolkien Estate. The original Estate copyright still holds, and then the annotations also acquire a new and independent copyright of their own. Likewise, the corporation that holds the copyright to Darth Vader (i.e., Walt Disney) has the exclusive right to create or authorize any derivative works of that character, including photographs or drawings of him which portray him in novel and creative ways, since (as court decisions put it) that is one aspect of the copyright holder's work that they might want to exploit commercially. In the same manner, anyone can make a movie based on The Bible, and may make their own movie called "The Ten Commandments" based on the Biblical chapter Exodus, but may not make a new version of the 1956 film, "The Ten Commandments", even with substantial new creative input, without getting permission of Paramount Pictures (the copyright holder).
If I take a picture of an object with my own camera, I hold the copyright to the picture. Can't I license it any way I choose? Why do I have to worry about other copyright holders?
By taking a picture with a copyrighted cartoon character on a t-shirt as its main subject, for example, the photographer creates a new, copyrighted work (the photograph), but the rights of the cartoon character's creator still affect the resulting photograph. Such a photograph could not be published without the consent of both copyright holders: the photographer and the cartoonist.
It does not matter if a drawing of a copyrighted character's likeness is created entirely by the uploader without any other reference than the uploader's memory. A non-free copyrighted work simply cannot be rendered free without the consent of the copyright holder, not by photographing, nor drawing, nor sculpting (but see Commons:Libertà di panorama).
Locations such as theme parks usually allow photography and sometimes even encourage it even though items of copyrighted artwork will almost certainly be included in visitors' photos. Such policies, however, do not automatically mean that such photos can be distributed under a public domain dedication or a free content license; the intent of a venue allowing photography may be to facilitate photography for personal usage and/or non-commercial sharing on social networking sites, for example. (See this discussion.) Also, the legal concept of de minimis can apply in such a setting: if the subject of your theme park photograph is your daughter eating an ice cream but someone in a Mickey Mouse costume can be seen in the background, this is not considered infringement nor a derivative work so long as it is clear from the photograph that you are interested in the girl and the frozen treat rather than the oversized rodent, and you may even market that image commercially (though you must be sure that Mickey really is "de minimis" and his presence must not make that image more useful, more interesting, or more marketable than it would be without him).
If I take a photograph of a kid who is holding a stuffed Winnie the Pooh toy, does Disney own the copyright in the photo since they own the Pooh design?
No. Disney does not hold the copyright on the photo. There are two different copyrights to be taken into account, that of the photographer (concerning the photo) and that of Disney (the toy). You have to keep those apart. Ask yourself: Can the photo be used as an illustration for "Winnie the Pooh"? Am I trying to get around restrictions for two-dimensional pictures of Pooh by using a photo of a toy? If so, then it is not allowed.
Be aware, though, that Disney's protection strategy both relies on author's right (artistic property) and trade mark (extended to protect a design). The actual legal analysis would be more subtle in that case. While Disney does not hold a copyright on the photo, there may be an infringement on Disney's copyright of Pooh by virtue of copying via the photograph. As virtually all photography is considered to involve at least a modicum of creativity on the part of the photographer, in fact you may have created a derivative work without permission.
Isn't every product copyrighted by someone? What about cars? Or kitchen chairs? My computer case?
No. There are special provisions in US copyright law to exempt utility articles to a wide degree from copyright protection:
Sculptures, paintings, action figures, and (in many cases) toys and models do not have utilitarian aspects and therefore in the United States (where Commons is hosted) such objects are generally considered protected as copyrighted works of art. A toy airplane, for example, is mainly intended to portray the appearance of an airplane in a manner similar to that of a painting of an airplane. On the other hand, ordinary alarm clocks, dinner plates, gaming consoles— as well as actual, full-scale planes— are not generally copyrightable... though any design painted on the dinner plate would likely be subject to copyright protection, as would an alarm clock in the shape of Snoopy the dog.
It is possible for utilitarian objects to have aspects which are copyrightable, but there is no clear line in US law between works which are copyrightable and objects which are not. A white paper on copyright and 3D printing mentioned several US court rulings that were each about whether a functional object had artistic elements that were "physically or conceptually" separable from the object's functional aspects and therefore copyrightable. The whitepaper suggested a consideration for determining if specific elements of a utilitarian object are copyrightable under US law: if an object has non-functional elements, then those elements are more likely to be copyrightable if the design of the elements was not influenced by utilitarian pressures.
Different countries may have different definitions: German law has a term called Schöpfungshöhe, which is the threshold of originality required for copyright protection. In the vast majority of national jurisdictions, the level of originality required for copyright protection of works of applied arts does not differ from the one for the fine arts. It is higher in Germany, Italy, Japan, Russia, Slovenia, and Switzerland. There is no legal definition for this threshold, so one must use common sense and existing case law.
Instead of copyright protection, utilitarian objects are generally protected by design patents, which, depending on jurisdiction, may limit commercial use of depictions. However, patents and copyright are separate areas of law, and works uploaded to Commons are only required to be free with respect to copyright. Therefore, patents of this kind are not a matter of concern for Commons.
Photos of people in costumes of copyrighted characters may or may not be copyrighted. See Commons:Copyright rules by subject matter/it (Costumes and cosplay) for more information. These should be decided on a case-by-case basis using the separability test.
It is prohibited to copy text from non-free media like copyrighted books, articles or similar works. Information itself, however, is not copyrightable, and you are free to rewrite it in your own words. Quotations are allowed if they are limited in size and mention the source.
In the United States, many maps are in the public domain. The most common cases are:
- The map was created by the US government: The federal government is the greatest source of public domain maps in the United States. Federal agencies are creating maps all the time and works that US government employees create (as part of their jobs) are not protected by copyright.
- The map’s copyright has expired: All maps published in the United States before 1925 are in the public domain because their copyrights have expired.
- The map was published before 1989 without a copyright notice: Copyright notices used to be mandatory. If a work was published without a proper notice, it went into the public domain unless the copyright owner corrected the problem within a specific period of time. A valid copyright notice on a map had to consist of at least these 2 elements: the copyright symbol ©, the word "Copyright," or the abbreviation "Copr." and the name of the copyright owner. (Example: © Lenny Longitude). Maps published from January 1, 1978 through March 1, 1989 also had to include the publication year. (Maps published before 1978 did not need to include the date).
- The map was not eligible for copyright in the first place: Not all maps get copyright protection in the United States. There are "originality" and "minimal creativity" requirements for copyright in the US. If the components of the map are "entirely obvious" the map will not be copyrightable. For example, an outline map of the state of Texas, or one of the US showing the state boundaries is not copyrightable. (Not creative.) Ditto maps that use standard cartographic conventions, like a survey map. (Not original.)
Even for maps which are copyrighted, not all the contents are subjected to copyright. The problems arise from the tension between the principle that maps are protected and two other basic principles: namely, that copyright does not protect facts and that copyright does not protect systems. Traditional maps are pictorial representations of geographic and demographic facts organized to allow the user to readily understand and easily extract the factual information portrayed. The factual information, such as boundary lines and locations of landmarks, is supposedly unprotected. The organizing principle for presenting the information will often, if not always, be deemed an unprotected system or idea. Thus, many maps will apparently contain only unprotected elements.
The issue was the object of several court cases. The tension among traditional copyright principles as they apply to maps has been heightened by Feist Publications, Inc. v. Rural Telephone Service Company, Inc. The Feist decision follows standard copyright dogma to the conclusion: copyright protects only expression, not facts; the expression protected must be the product of intellectual creativity and not merely labor, time, or money invested; the protected elements of the resulting work are precisely those that reflect this intellectual creativity, and no more. This is the conclusion of a court of law on the issue.
As a result of the court decisions, following parts of a map are in the public domain, and may be used freely:
- Place names: Those are not copyrightable.
- Colors: For example, the colors representing area features on a topographic map, such as vegetation (green), water (blue), and densely built-up areas (gray or red). Colors are not copyrightable, either.
- Symbols and map keys: Cannot be protected by copyright, even if the mapmaker invented truly original ones.
- Geographic or topographic features: Those are facts, and facts are not copyrightable.
- Elements copied from other maps: (say, from a public domain USGS map). Whatever new information the mapmaker added will be protected by copyright (the selection, arrangement of the info), but the elements that were copied (the elements of a USGS map used as a starting point, for example) will stay in the public domain.
However, some of these maps may be protected by copyright. A map is not copyrightable if the idea it expresses could only be done in one way. The court found that there was сreativity involved in the idea here was to bring together the available information on boundaries, landmarks, and ownership, and to choose locations and an effective pictorial expression of those locations. But the protection that each map receives extends only to its original expression, and neither the facts nor the idea embodied in the maps is protected.
While the above applies to the United States, it is not clear if it is applicable to other countries. In the European Union Directive 96/9/EC of the European Parliament and of the Council of 11 March 1996 on the legal protection of databases has been approved. However, neither the directive, nor any of the national laws promulgated after its approval clearly specify that elements represented on maps qualify as databases.
In Germany a verdict of the court in München of November 9, 2005, stated that, according to the German Copyright Law topographic maps are to be considered databases, as defined in art. 87 of the law and the information is protected according to the provisions regarding databases. This also refers to the length of the protection of databases which is significantly shorter than the protection of copyright. In any case, the copyright for databases according to the Directive is of fifteen years, implying that, regardless of the interpretation, the information on maps which could be interpreted as being database related expires in 15 years after the publication of the map.
I know that I can't upload photos of copyrighted art (like paintings and statues), but what about toys? Toys are not art!
Vedi anche : Category:Toys related deletion requests
Although the scope of copyright varies between countries, it is a misconception that copyright applies solely to "art". Instead, copyright typically applies to a larger variety of works; to use the United States, where WMF servers are located, as an example: copyright protection is available to “original works of authorship fixed in any tangible medium of expression” Indeed, toys generally are original (owe their origin to an author), have authors (human creators), and are fixed in a tangible medium (wood, fabric, etc.)
The question, then, is whether toys are to be treated as vehicles and furniture: exempt from copyright protection on the basis of being utilitarian objects. Indeed, some countries, such as Japan, generally consider toys to be utilitarian objects and therefore ineligible for copyright. Other countries, such as the United States, however, do not consider toys to be utilitarian objects. Accordingly, paintings, statues and toys are all works subject to copyright whose photographs would require permission of the original creator to be hosted on the Commons. Just as you cannot upload pictures of a sculpture by Picasso, you cannot upload photographs of Mickey Mouse or Pokémon figures.
The legal rationale in the United States has been established in numerous cases. "Gay Toys", for example, found "a toy airplane is to be played with and enjoyed, but a painting of an airplane, which is copyrightable, is to be looked at and enjoyed. Other than the portrayal of a real airplane, a toy airplane, like a painting, has no intrinsic utilitarian function." Additional rulings have found, for example, "it is no longer subject to dispute that statues or models of animals or dolls are entitled to copyright protection" and "There is no question but that stuffed toy animals are entitled to copyright protection."
Similarly, dolls' clothing has been found to be copyrightable in the US on the grounds that it does not have a utilitarian function of providing protection from the elements or preserving modesty in the manner that clothing for humans does (the latter is a "useful article.") Numerous lawsuits have shown that Mickey Mouse or Asterix have to be treated as works of art, which means they are subject to copyright, while a common spoon or a table are not works of art. Artistic elements of these items could be copyrighted, but only if it's separable from the utilitarian elements. Some toys are also too simple to meet the threshold of originality, for example, the Kong dog toy.
In other cases, the "separability" test may be needed (see Star Athletica, LLC v. Varsity Brands, Inc.). When uploading a picture of a toy, you must show that the toy is in the public domain in both the United States and in the source country of the toy. In the United States, copyright is granted for toys even if the toy is ineligible for copyright in the source country.
But Wikimedia Commons isn't commercial! And what about fair use?
Wikimedia Commons is not a commercial project, but the project scope requires that every single file be licensed for possible commercial reuse and be free of third-party copyrights. Fair use arguments are not allowed on Commons. "Fair use" is a difficult legal exception that exists only for pictures that are used in a certain limited context; it is never applicable to entire databases of copyrighted material.
But how can we illustrate topics like Star Wars or Pokémon without pictures?
Admittedly, it may be difficult or even impossible to illustrate such articles. However, the articles can still be written. Their lack of illustrations will not affect the vitality of Wikimedia's projects, and there are plenty of topics with opportunities to create illustrations which do not violate third-party copyrights. Even your own drawing of Pikachu cannot be published under a free license.
Some Wikimedia projects allow non-free works (including derivatives of non-free works) to be uploaded locally under fair use provisions. The situations in which this is permitted are strictly limited. It is vital to consult the policies and guidelines of the project in question before attempting to invoke fair use claims.
What about images of copyrighted characters in public domain works?
Sometimes individual works featuring copyrighted characters (such as Mickey Mouse or Superman) enter the public domain. Although the works themselves are in the public domain, any portions that include the copyrighted characters are still restricted by copyright law. This concept even extends to non-sentient "characters", such as the Batmobile. Derivative representations of characters are protected by copyright law in the United States until the original work that created the character is no longer copyrighted. This protection is separate from trademark protection.
I've never heard about this before! Is this some kind of creative interpretation?
Actually, no. Photographs of, say, modern art statues or paintings cannot be uploaded either, and people accept that. If we accept the legal standard that comic figures and action figures can be considered as art and thus are copyrighted, we are just applying the standard rule here.
Vedi anche : Commons:Copyright rules by subject matter/it.
How does this policy concern the selection of images that are allowed on Wikimedia Commons?
- Comic figures and action figures: No photographs, drawings, paintings or any other copies/derivative works of these are allowed (as long as the original is not in the public domain). No pictures are allowed of items which are derivatives from copyrighted figures themselves, like dolls, action figures, t-shirts, printed bags, ashtrays etc.
- Paintings with frames: Paintings that are in the public domain are generally allowed (see Commons:Licenze). Frames are 3-dimensional objects, so the photo may be copyrighted. Remember: Always provide the original creator's name, birth and death date and the time of creation, if you can! If you do not know, give as much source information as possible (source link, place of publication etc.). Other volunteers must be able to verify the copyright status. Furthermore, the moral rights of the original creator—which include the right to be named as the author—are perpetual in some countries. In either case you need permission from the author to create a derivative work. Without such permission any art you create based on their work is legally considered an unlicensed copy owned by the original author (taking from another web site is not allowed without their permission).
- Cave paintings: Cave walls are usually not flat, but three-dimensional. The same goes for antique vases and other uneven or rough surfaces. This could mean that photographs of such media can be copyrighted, even if the cave painting is in the public domain. (We are looking for case studies here!) Old frescoes and other paintings on flat surfaces in the public domain should be fine, as long as they are reproduced as two-dimensional artworks.
- Photographs of buildings and artworks in public spaces: Those are derivative works, but they may be OK, if the artwork is permanently installed (which means, it is there to stay, not to be removed after a certain time), and in some countries if you are on public ground while taking the picture. Check Commons:Libertà di panorama. If your country has a liberal policy on this exception and learn more about freedom of panorama. Note that in most countries, freedom of panorama does not cover two-dimensional artworks such as murals.
- Replicas of artworks: Exact replicas (even poor ones) of public domain works, like tourist souvenirs of the Venus de Milo, cannot attract any new copyright as they do not have the required originality. Hence, photographs of such items can be treated just like photographs of the artwork itself.
- Photographs of three-dimensional objects: always copyrighted, even if the object itself is in the public domain. If you did not take the photograph yourself, you need permission from the owner of the photographic copyright (unless of course the photograph itself is in the public domain).
- Images of characters/objects/scenes in books: subject to any copyright on the book itself. You cannot freely create and distribute a drawing of Albus Dumbledore any more than you could distribute your own Harry Potter movie. In either case you need permission from the author to create a derivative work. Without such permission any art you create based on their work is legally considered an unlicensed copy owned by the original author.
