Wikivoyage:Copyleft Voyage Tips and guide

This page in a nutshell: All written contributions to this project are automatically licensed under the CC BY-SA 4.0 License. All content added to Wikivoyage articles must be original work or from a source that has been explicitly licensed under CC BY-SA or a compatible licence.

Contents

Wikivoyage uses a copyleft license for all content on the website. Anyone can use Wikivoyage content according to the terms of the Creative Commons Attribution-ShareAlike license. And anyone can contribute their own or other people's content, as long as the work is their own or available under a compatible license.

It is very important that you understand how copyleft works before you contribute to Wikivoyage. If you find your work reused by someone else in a manner that you didn't consider, or if you stop using Wikivoyage for any reason, it is not possible to change the license for the work you have done. Although you always own the copyright in your work, that does not give you the right to change its license retroactively.

If this seems confusing, skip down to the FAQ.

All written contributions to Wikivoyage are and must be licensed under Creative Commons Attribution-ShareAlike 40 (CC-by-SA 4.0) or a compatible license (e.g., Public Domain, CC-by-SA any, dual CC-by-SA/GFDL any, etc.). Consequently, all redistributed and derivative works of Wikivoyage text must also be licensed as CC-by-SA 4.0.

Images almost always must be uploaded to Wikimedia Commons, and images' individual licensing is described on individual image pages. Any images hosted locally on Wikivoyage comply with our Wikivoyage:Non-free content, meaning that they do have a license compatible with our copyleft, but are derivative works of something not free, like a work of art. As with text contributions, all files uploaded here must have a license that allows derivative works and commercial re-use (usually CC-by or CC-by-SA, never CC-No Derivatives or CC-Non-Commercial)—see Wikivoyage:Non-free content#Exemption Doctrine Policy for more information.

All redistributed and derivative works including Wikivoyage images and other files must provide file-specific attribution and licensing information, available on the individual file page.

Copyleft means that every single author, editor, illustrator, mapmaker, factchecker and photographer who puts their work into Wikivoyage gives you the right to read, copy, print, save, download, read aloud, project, modify, email, distribute, sell, photocopy and correct their work however you want to.

The only restrictions are that:

• if you distribute it, or derive new work from it
  • you must give attribution to the creators
  • you must retain the work and any derivative works under the same licensing.

In other words, we give you practically every freedom within the boundaries of the law to use the information in Wikivoyage, except the freedom to take that freedom away from others.

The license we use for the text is the Attribution-ShareAlike 4.0 (often abbreviated as "CC BY-SA 4.0") by the great people at Creative Commons. It's a piece of legal documentation that basically says the same thing as above: give Wikivoyagers credit for their work, and share with other people.

For the purposes of the License, a Work is the formatted text that makes up a single Wikivoyage article. Each image individually is also a Work for the purposes of the License; only some of them use the same license as the text, but they are either in the public domain in the U.S.A. (and often globally) or have a license giving the same freedoms; images differ in the specific requirements.

In addition, there may be other restrictions on use or distribution based on law in your country or state; in particular, consider privacy rights for photographs of identifiable people and derivative works for photographs of buildings and artworks.

Lastly, there is no warranty on any of the articles or images in Wikivoyage. Hotels close; bars raise prices; train schedules change; earthquakes, mudslides, wars and lightning strikes destroy sights, statues and cities. People make mistakes. Wikivoyagers try their best, but none of the creators of these pages are responsible to you in any way for any injury or discomfort you endure before, after, or during your travels. See the License above for details.

If you want to reuse any of our travel guides, whether to build a mirror site, distribute travel information for your city or even build some new gee-whiz travel application, you might want to check out Wikivoyage:How to re-use Wikivoyage guides.

Copyleft means that every single yahoo, nutcase, screwjob, charlatan, shyster, weirdo, freakazoid, mouthbreather, goofball, lamer, cheater and jerk will have the right to read, copy, print, save, download, read aloud, project, modify, email, distribute, sell, photocopy and correct your work however they want to.

In particular, your work can be ruthlessly modified, edited, or cut from Wikivoyage altogether by other Wikivoyagers. It can be photocopied thousands of times and passed around as flyers by itinerant backpackers. It can be put in Hollywood movies, and it can be projected onto a screen at an outdoor rave. It can be used for commercial ventures, advertisements, or other purposes (with some restrictions) without your direct control.

In return for your incredible generosity, you will have the knowledge that you are helping travellers all over the world, and that all copies made of your work should be (indirectly) attributed to you, and that everyone who derives new works from yours should have to be just as generous as you are. And, of course, you get to use all the other work in Wikivoyage shared the same way; but you don't need to contribute to do that.

You'll also get the pleasure of collaborating with hundreds of other Wikivoyagers just like yourself. You'll get free spellcheck service from nit-picky folks you've never met. You'll work together with people you don't know to make better pictures, text, and maps than you've ever dreamed of. You still retain the copyright over your own work, and you can use it any other way you want (even if it's not compatible with our license!). By writing on Wikivoyage, or uploading photos, you're using a license under which all our work is available - making it simpler for everyone.

Now, the hard part: because of the Attribution-ShareAlike license, you are legally responsible not to put other people's copyrighted work into Wikivoyage without permission. You are responsible for getting model releases from people you take pictures of, and you are responsible for any libel you include in your articles.

Before editing Wikivoyage articles or uploading pictures, you should read very carefully the full text of the Attribution-ShareAlike 4.0 license, and make sure that you agree to it.

We want to make the best possible travel guide, with the most brilliant writing, the most up-to-date info, the most awe-inspiring photos, the most detailed and readable maps. But no one item is worth putting yourself and this project in legal jeopardy. If you have any questions about the source of something you want to put in Wikivoyage, ask about it first. When in doubt, leave it out.

Nothing! Just plunge forward! Whenever you save something you write, you automatically license it for use under CC-by-SA 4.0. So all you need to do is get started writing—if the text is your own original writing, don't worry about licenses.

You need an account on Wikimedia Commons ("Commons"), our central image repository. Create the account first if you don't have one yet. The registration doesn't involve sharing any information, other than what you choose to share (registering an email address allows you to get a new password instead of a lost one).

Before uploading, be sure that the image is either one created by you or one that is freely licensed (see "Can I copy text and other content to Wikivoyage from other sites?" below). Then go ahead and upload it.

If your image is a photo of a work of art or architecture, you may need to upload it locally under our Exemption Doctrine. Check Commons:Freedom of Panorama to see whether the laws of the country where the photo was taken allow derivative works of publicly displayed art or architecture. If the image cannot be uploaded to Commons because of Freedom of Panorama issues, upload it here (but otherwise, with few exceptions, never upload anything here!). If you have no idea what this means, feel free to ask at the Arrivals lounge.

You will only be attributed for your work if you register a user account. You will be attributed by your user name, which appears in article history and credits pages. For an example, take a look at the history of this page. Re-users will have to provide attribution as well—online re-users will usually link back to the article being re-used, while offline re-users will simply state the source.

For files you upload, you must provide the attribution information yourself in the upload summary. So, just indicate however you want to be attributed as you upload the file.

Usually No. That is, unless you are the original author of the text, or the other website has been explicitly licensed as compatible with Creative Commons Attribution/Attribution-ShareAlike 4.0, or it is in the public domain.

If you are the original author of the text, note that on the article talk page, or else someone will likely remove it as a copyright violation.

Wikimedia projects like Wikipedia have a compatible license, so we can copy relevant text as long as proper attribution is provided in accordance with the CC-SA license. When copying text from another site with a compatible license, you must cite the article from which you are copying in the edit summary and include a link to the license terms.

For the content to be public domain, it needs to be created by the U.S. Federal Government, the city government of Washington, D.C., or have a statement on the website saying it is released into the public domain. That great picture you took of the RMS Titanic leaving port is likely also safe for anyone to use; copyright does eventually expire (depending on date and place of publication) and an author is free to release their own work to the public domain at any time.

Lack of a copyright notice does not mean the content is free to re-use—all online content is automatically copyrighted unless the author explicitly states otherwise.

Probably not. Just because a map, brochure, or other item is given away for free does not mean that it has been freely licensed. For content to be usable on Wikivoyage the content copyright owner must agree to license it under the CC-SA 4.0 or a compatible license.

The following template can help. Please quote your original message and reply to it at the respective article's Talk page. You may provide attribution to the original author(s) listing them by a template like Template:Attribution.

Hello (person name).

Do you mind if I use some of your work at <work name> to contribute to an article on <destination> at Wikivoyage, a free online travel guide written and edited entirely by travelers from around the globe?

The current version of the article I am going to update is here: <article permalink URL>.

Wikivoyage requires all of its content to be licensed under Creative Commons Attribution-ShareAlike 4.0 license or another suitably compatible copyleft license. Basically this means that your content:

- can be distributed by others, even for commercial purposes, as long as you are credited as the author

- may be further modified by other contributors

So do you mind if I use your work for Wikivoyage?
