The following should be read in conjunction with the Conditions of Use:

Summary:  The Creative Commons CC-BY-NC-SA license applies to material on the Emergency 2.0 Wiki sites.  This means that:

  • you may use and adapt material on the Emergency 2.0 Wiki sites as long as you provide attribution for the source, do not use it for commercial purposes, and agree to permit others to use your version of the content on the same terms;
  • when you contribute your own material to the Emergency 2.0 Wiki Sites, you agree to permit others to use your material in the same way; and 
  • you must take care not to infringe the intellectual property rights of others.  

The Emergency 2.0 Wiki is an online open-content collaborative initiative, that is, a voluntary project including individuals and groups working to develop a common resource of human knowledge. As the whole premise of the wiki is built on sharing and collaboration, this work is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 3.0 Unported License.

This license enables you to share, copy, distribute, remix and adapt this site’s content (we encourage you to!) However if you do, you will need to make it available for free. For example, you are welcome to incorporate guidelines, checklists and tools that are posted on an Emergency 2.0 Wiki site into an Ibook or Smartphone app – as long as you make it available to the public for free.

In the spirit of sharing and collaboration and advancing knowledge, we also ask that you “share alike” which means that you make that work available under the same license.

Please also attribute in the form: “Sourced from Emergency 2.0 Wiki“ and provide a link to the site and the page where possible.

This section of the Emergency 2.0 Wiki is a simplified adaptation of the guidelines at Wikipedia: Copyrights.

Use of content on the Emergency 2.0 Wiki sites

If you wish to reuse content from Emergency 2.0 Wiki sites, first read the “Reusers’ rights and obligations” section below. You should then read the Creative Commons Attribution-NonCommercial-ShareAlike 3.0 Unported License.  You should also read the terms and conditions of any third party site on which the material is hosted.

The content of Emergency 2.0 Wiki sites is copyrighted (automatically, under the Berne Convention) by Emergency 2.0 Wiki site contributors and is formally licensed to the public under one or several liberal licenses. Most of Emergency 2.0 Wiki site’s text and many of its images are co-licensed under the Creative Commons Attribution-NonCommercial-ShareAlike 3.0 Unported License (CC-BY-NC-SA). Images may have a description page which indicates the license under which it is released or, if it is non-free, the rationale under which it is used.

The licenses the Emergency 2.0 Wiki uses grant free access to the content on Emergency 2.0 Wiki sites in the same sense that free software is licensed freely. Content developed for the Emergency 2.0 Wiki site content can be copied, modified, and redistributed if and only if the copied version is made available on the same terms to others and acknowledgment of the Emergency 2.0 Wiki is included (including a link back to the Emergency 2.0 Wiki site). Copied Emergency 2.0 Wiki site content will therefore remain free under appropriate license and can continue to be used by anyone subject to certain restrictions, most of which aim to ensure that freedom. This principle is known as copyleft  in contrast to typical copyright licenses.

To this end,

  • Permission is granted to copy, distribute and/or modify Emergency 2.0 Wiki site text under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike 3.0 Unported License.
  • A copy of the Creative Commons Attribution-ShareAlike 3.0 Unported License is available at
  • Content on the Emergency 2.0 Wiki sites is covered by disclaimers.

However, your right to access, copy or use Emergency 2.0 Wiki text hosted on third party websites may be restricted by the terms and conditions of the third party website.

The English text of the CC-BY-NC-SA license is the only legally binding restriction between authors and users of Emergency 2.0 Wiki content concerning copyright. What follows is our interpretation of CC-BY-NC-SA, adapted from Wikipedia, as it pertains to the rights and obligations of users and contributors.

Contributors’ rights and obligations

If you contribute text directly to Emergency 2.0 Wiki sites, you thereby license it to the public for reuse under the CC-BY-NC-SA license. Non-text media may be contributed under a variety of different licenses that support the general goal of allowing unrestricted re-use and re-distribution.

See “Guidelines for images and other media files”, below.

If you want to import text that you have found elsewhere or that you have co-authored with others, you can only do so if it is available under terms that are compatible with the CC-BY-NC-SA license.

You retain copyright to materials you contribute to Emergency 2.0 Wiki sites, text and media. Copyright is never transferred to Emergency 2.0 Wiki Ltd or any Emergency 2.0 Wiki personnel. You can later republish and relicense the materials in any way you like. However, you can never retract or alter the license for copies of materials that you place on an Emergency 2.0 Wiki site; these copies will remain so licensed until they enter the public domain when your copyright expires (currently some decades after an author’s death). You consent to your materials being attributed in the form ‘Sourced from Emergency 2.0 Wiki’.

Using copyrighted work from others

All creative works are copyrighted, by international agreement, unless either they fall into the public domain or their copyright is explicitly disclaimed. There are some circumstances under which copyrighted works may be legally utilized without permission; see “Non-free materials and special requirements” below. However, it is Emergency 2.0 Wiki Ltd’s goal to be able to freely redistribute as much of Emergency 2.0 Wiki sites’ material as possible, so original images and sound files licensed under CC-BY-NC-SA or in the public domain  are greatly preferred to copyrighted media files used under fair dealing, fair use  or otherwise.

If you want to import media (including text) that you have found elsewhere, and it does not meet the criteria outlined under the heading “Non-free materials and special requirements” below, you can only do so if it is public domain or available under terms that are compatible with the CC-BY-NC-SA license. If you import media under a compatible license which requires attribution, you must, in a reasonable fashion, credit the author(s). You must also in most cases verify that the material is compatibly licensed or public domain. If the original source of publication contains a copyright disclaimer or other indication that the material is free for use, a link to it on the media description page or the article’s talk page may satisfy this requirement. If you obtain special permission to use a copyrighted work from the copyright holder under compatible terms, you must make a note of that fact (along with the relevant names and dates) and verify this through one of several processes. The procedures outlined at Wikipedia:Requesting copyright permission may be adapted for asking a copyright holder to grant a usable license for their work and for  verifying that license has been granted.

Never use materials that infringe the copyrights of others. This could create legal liabilities and seriously hurt the Emergency 2.0 Wiki project. If in doubt, write the content yourself, thereby creating a new copyrighted work which can be included in Emergency 2.0 Wiki sites without trouble. Note that copyright law governs the creative expression of ideas, not the ideas or information themselves. Therefore, it may be legal to read an encyclopedia article or other work, reformulate the concepts in your own words, and submit it to Emergency 2.0 Wiki sites, so long as you do not follow the source too closely. However, it would still be unethical (but not illegal) to do so without citing the original as a reference.

Linking to copyrighted works

Since most recently-created works are copyrighted, almost any Emergency 2.0 Wiki material which cites its sources will link to copyrighted material. It is not necessary to obtain the permission of a copyright holder before linking to copyrighted material, just as an author of a book does not need permission to cite someone else’s work in their bibliography. Likewise, Emergency 2.0 Wiki sites are not restricted to linking only to CC-BY-NC-SA or open-source content.

However, if you know or reasonably suspect that an external website is carrying a work in violation of the creator’s copyright, do not link to that copy of the work. An example would be linking to a site hosting the lyrics of many popular songs without permission from their copyright holders. Knowingly and intentionally directing others to a site that violates copyright has been considered a form of contributory infringement. Linking to a page that illegally distributes someone else’s work sheds a bad light on Emergency 2.0 Wiki project and Emergency 2.0 Wiki participants.

The copyright status of Internet archives is unclear, however. It is currently acceptable to link to Internet archives such as the Wayback Machine, which host unmodified archived copies of webpages taken at various points in time. In articles about a website, it is acceptable to include a link to that website even if there are possible copyright violations somewhere on the site.

Context is also important; it may be acceptable to link to a reputable website’s review of a particular film, even if it presents a still from the film (such uses are generally either explicitly permitted by distributors or allowed under fair dealing or fair use). However, linking directly to the still of the film removes the context and the site’s justification for permitted use or fair dealing or fair use.

Copyright violations

Contributors who repeatedly post copyrighted material despite appropriate warnings may be blocked from editing by a member of the Emergency 2.0 Wiki personnel to prevent further problems.

If you suspect a copyright violation, you should at least bring up the issue on that page’s discussion page. Others can then examine the situation and take action if needed. Some cases will be false alarms. For example, text that can be found elsewhere on the Web that was in fact copied from an Emergency 2.0 Wiki site in the first place is not a copyright violation.

If a page contains material which infringes copyright, that material – and the whole page, if there is no other material present – should be removed.

Guidelines for images and other media files

Images, photographs, video and sound files, like written works, are subject to copyright. Someone holds the copyright unless they have been explicitly placed in the public domain. Images, video and sound files on the Internet need to be licensed directly from the copyright holder or someone able to license on their behalf. In some cases, fair dealing or fair use guidelines may allow them to be used irrespective of any copyright claims; see “Non-free materials and special requirements” section below for more.

Image description pages must be tagged with a special tag to indicate the legal status of the images, following the principles described at Wikipedia:Image copyright tags. Untagged or incorrectly-tagged images will be deleted.

Governing copyright law

The Emergency 2.0 Wiki project is based in Australia and accordingly governed by Australian copyright law. However, Emergency 2.0 Wiki site contributors should respect the copyright law of other nations, even if these do not have official copyright relations with Australia.

Reusers’ rights and obligations

The only Emergency 2.0 Wiki site content you should contact Emergency 2.0 Wiki personnel about is the Emergency 2.0 Wiki logos, which are not freely usable without permission. If you want to use other Emergency 2.0 Wiki site materials in your own books/articles/websites or other publications, you can do so, but only in compliance with the licensing terms and, where material is hosted on a third party website, the terms and conditions of the third party website.

Please follow the guidelines below:

Re-use of text


To re-distribute text on Emergency 2.0 Wiki sites in any form, provide a hyperlink  (where possible) or URL to the page or pages you are re-using and attribute in the form “Sourced from Emergency 2.0 Wiki”. This applies to text developed by Emergency 2.0 Wiki participants. Text from external sources may attach additional attribution requirements to the work, which should be indicated on an article’s face or on its talk page. For example, a page may have a banner or other notation indicating that some or all of its content was originally published somewhere else. Where such notations are visible in the page itself, they should generally be preserved by re-users.

Copyleft/Share Alike

If you make modifications or additions to the page you re-use, you must license them under the Creative Commons Attribution-NonCommercial-ShareAlike 3.0 Unported License or later.

Indicate changes

If you make modifications or additions, you must indicate in a reasonable fashion that the original work has been modified. If you are re-using the page in a wiki, for example, indicating this in the page history is sufficient.

Licensing notice

Each copy or modified version that you distribute must include a licensing notice stating that the work is released under CC-BY-NC-SA and either a) a hyperlink or URL to the text of the license or b) a copy of the license. For this purpose, a suitable URL is:

For further information, please refer to the legal code of the CC-BY-NC-SA License.

Non-free materials and special requirements

Emergency 2.0 Wiki sites may also include quotations, images, or other media under the Australian copyright law “fair dealing” doctrine. More information about fair dealing is available from the Australian Copyright Council Information Sheet “Fair Dealing – What Can I Use Without Permission” (G079). In Emergency 2.0 Wiki sites, such “fair dealing” material should be identified as from an external source by an appropriate method (on the image description page, or history page, as appropriate; quotations should be denoted with quotation marks or block quotation in accordance with the principles in Wikipedia’s manual of style. This leads to possible restrictions on the use, outside of Emergency 2.0 Wiki, of such “fair dealing” content retrieved from Emergency 2.0 Wiki: this “fair dealing” content does not fall under the CC-BY-NC-SA license as such, but under the “fair dealing” (or similar/different) regulations in the country where the media are retrieved.  The U.S. Copyright law “fair use” doctrine is dealt with in Wikipedia’s guidelines for non-free content.

If you are the owner of Emergency 2.0 Wiki-hosted content being used without your permission

If you are the owner of content that is being used on an Emergency 2.0 Wiki site without your permission, then you may request the page be immediately removed from Emergency 2.0 Wiki by contacting us on You may also blank the page but the text will still be in the page history. Either way, we will, of course, need some evidence to support your claim of ownership.

Inversely, if you are the editor of an Emergency 2.0 Wiki site article and have found a copy hosted without following the licensing requirements for attribution, please notify us on

Third party sites

Emergency 2.0 Wiki sites may be hosted by third parties such as Twitter, YouTube, SlideShare and LinkedIn. The owners of these sites have their own terms and conditions concerning copyright. When using any third party site, the terms and conditions of the owner of the site will apply to you and may in some cases prevail over these Conditions of Use. You must comply with those terms and conditions.

If you have any questions about this license, please contact us on
