Commons:Reutilização de conteúdo fora da Wikimedia/licenças

Below are summaries of licenses often used on Wikimedia Commons, and how to comply with them.

• The license(s) of a work can be found on its file description page. This is an example for a file description page.
• If a work is published under a single license, all of the terms in that license must be followed. If a work is multi-licensed (that is, released under more than one license), re-users may choose which license's terms they wish to follow. Except for materials believed to be in the public domain, a link to the full text of the license(s) is included on the file description page. Some licenses also have a summary available.
• Please read the full licenses for legal details. Neither the Wikimedia Foundation nor the creators of material on Wikimedia sites provide legal advice. If you need information about how a license applies to your particular situation, you should contact a suitable legal professional in your jurisdiction.

The feature "Use this file on the web"/"Use this file on a wiki" on the work's file description page may help you to follow the license's terms (currently not available in Internet Explorer, and only in Vector (standard) and Monobook skins).

Public domain

Content marked as public domain (or local equivalent, e.g. "may be used for any purpose") is material believed to be out of copyright, either because of expiration of the original copyright, or because the material has been explicitly released into the public domain by its creator(s).

Note that inalienable moral rights and other restrictions may still apply in some countries for some uses.

It is common for publishers to take public domain works and republish them under their own copyright. This may be legal, but it does not affect the public domain status of the original image. If you tag the image with its origin (where you got it and where it came from originally) and the name of the creator, this can help us if a dispute with such a publisher arises later.

Creative Commons

Most Creative Commons licenses are not free content licenses and will not be found as the sole allowable licence on Wikimedia Commons. The following are frequently used licenses on Commons:

CC-BY

Com a Creative Commons Attribution license (CC-BY), reutilizadores são livres para fazer trabalhos derivados, copiar, distribuir, apresentar e utilizar o trabalho mesmo para fins comerciais.

Deverá ser dado crédito ao(s) autor(es) e, quando reutilizando ou distribuindo o trabalho, deverão ser mencionados os termos da licença ou fornecido um link para eles. Poderá escolher se quer manter a sua versão sob a licença CC-BY.

The standard {{Cc-by-3.0}} template

CC-BY-SA

Com a Creative Commons Attribution license (CC-BY-SA), reutilizadores são livres para fazer trabalhos derivados, copiar, distribuir, apresentar e utilizar o trabalho mesmo para fins comerciais.

Quando reutilizando ou distribuindo o trabalho deverá ser dado crédito ao(s) autor(es) e deverão ser mencionados os termos da licença ou fornecido um link para eles. Deverá manter a sua versão sob a licença CC-BY-SA.

Licenças GNU

GNU Free Documentation License

For simple redistribution, include the version you were given access to and its complete history with attribution, and include the GFDL (linked on the same website or reprinted in print). Compliance is easy on websites or in books, but (presently) difficult for leaflets, magazines or newspapers.

Com a GNU Free Documentation License, reutilizadores são livres para fazer trabalhos derivados, copiar, distribuir, apresentar e utilizar o trabalho mesmo para fins comerciais. No entanto deverá ser dado crédito aos últimos cinco maiores contribuidores, ou aos criadores do trabalho, assim como deverá ser incluída uma cópia completa da licença GFDL (link para site de internet ou impresso).

A metodologia utilizada para determinar os cinco contribuidores mais substanciais, segundo os termos da GFDL, não está definida em termos legais, mas é aconselhável a utilização de um método consistente, como a contagem de edições, de palavras, horas de contribuição, ou outro método de natureza similar.

Todos os trabalhos derivados de um trabalho sob a licença GFDL deverá permanecer sob a mesma licença.

When using a photo placed under the GFDL license as part of a larger work, the larger work does not have to be released under GFDL for usage to be within the license terms. The Free Software Foundation, creators of the GFDL license, has been asked for clarification of how much of e.g. a book counts as the "larger work" in these terms; they responded that no synopsis can substitute for what the text of the license says, and if in doubt the reuser should seek a proper legal opinion. Now, the GFDL says "When the Document is included in an aggregate, this License does not apply to the other works in the aggregate which are not themselves derivative works of the Document." So, the larger work doesn't (always) have to be released under GFDL.

GNU GPL e LGPL

A licença GPL é mais comumente utilizada para software informático, e não tanto para materiais textuais. Mesmo assim, algum conteúdo, como imagens no Commons, foram lançadas sob a licença GPL. É recomendado utilizar este conteúdo com alguma cautela.

For simple redistribution of such material, including altered versions, (a) release your version under the same license (b) supply the source version, i.e. something as editable as what you started with (e.g. image file, GIMP .xcf file, etc.).

A GNU General Public License (GPL) e a GNU Free Document License (GFDL) não são compatíveis, o que significa que material com uma das licenças atribuídas não pode ser licenciado simultaneamente com a outra.
