Creative Commons (CC) is a world-wide, non-profit organisation that provides tools for free, open licensing.  CC licences work within copyright to allow materials to be shared, reused and remixed, legally.

CC-licensed materials have granted permissions that make reuse easy to understand.  All CC-licensed materials have a requirement for attribution - Best practices for attribution.

Copyright owners can choose what elements to include a CC licence, based on what permissions they would like to grant to users.

The open licensing attached to material may not always be obvious. Some open material may have had new licensing applied that has changed its usage permissions (e.g. an older journal article that was originally published as 'all rights reserved'). Some organisations apply licensing via an overarching statement on their website (e.g. certain National and State Government documents).

If the open licensing isn't obvious:

• Scrolling down through the hosting (or abstract) page for the material can provide the answer. Licensing information may be included in a notes, citation, rights or supplementary section.
• For articles and other documents, check the PDF - licensing can be stated on a cover sheet, at the top or bottom of the first page, on the verso (the page after the title page), or on the final page / back cover of the document.
• Online, look for a link that might have the information. On journal sites, look for a 'Copyright', 'Permissions' or 'Reprints' link on the abstract page - many publishers have set these pages up to spell out the license information to save users from going through the copyright request process.  On other sites, look for a page link such as 'Copyright', 'Licensing' or 'Terms of Use' (often in the site footer).

Note that just because a resources is listed as having 'free' access, does not mean that it is open-licensed.

There is often confusion that where material is publicly available it is in the 'public domain', which isn’t true for copyright - most material available online and elsewhere is very much still protected. True public domain works are not restricted by copyright due to age, form, function, or for other reasons. You can copy, distribute, display, perform, modify, or otherwise (re)use public domain works for any purpose, including without attribution. Creative Commons (CC) has two public domain tools - 'CC0' and 'PDM'.

CC0 Public Domain Dedication tool

CC0 Public Domain Dedication is often grouped with the 6 CC licences noted above, but it is actually a separate tool that changes the copyright status of a work to the fullest extent allowed under a country’s legislation. While CC licences take a ‘some rights reserved’ approach, CC0 functions as ‘no rights reserved' and includes a backup function as a permissive licence. This is important for jurisdictions where creators are not able to surrender or waive certain rights.

• CC0 should only be applied to your own work, or where you have authorisation for the works of others. Read the CC0 FAQs.
• CC0 is often recommended for use with research data. Read more in our guide to research data and copyright (PDF).
• CC0 has been approved for use with software by the Free Software Foundation (FSF), and is compatible with many open software licences. There is a notice that the FSF recommends adding.

Public Domain Mark (PDM)

The Public Domain Mark (PDM) functions as a label for users to identify works that are free of copyright restrictions. Note that application of the PDM lacks the legal backing that is included with CC0. Care should be used when using materials marked with the PDM, as the copyright status of works can vary by jurisdiction, and the PDM can be applied by anyone (accurate or not).

The Free Art License grants the right to freely copy, distribute, and transform creative works without infringing the creator’s rights. It is designed to promote and protect creative expressions via the principles of ‘copyleft’ – the ability to freely use, copy, distribute, transform works, while not allowing for exclusivity.

Version 1.3 of the Free Art License is compatible with the Creative Commons Attribution Share-Alike (BY-SA) 4.0 licence - only this specific licence and version. For more on Creative Commons, see the information above.

Open Data Commons is a set of legal tools and licenses to help you publish, share, and use open data. Learn more about the options from ODC:

• Open Data Commons Open Database License (ODbL) - Attribution and Share-Alike
• Open Data Commons Public Domain Dedication and License (PDDL)

The Community Data License Agreement (CDLA) is a collaborative licence to enable open access, sharing and use of data.

CDLA-Permissive-2.0 is a thorough rewrite of the 1.0 licence, streamlining the language and removing provisions that were not relevant or necessary in practice. The resulting 2.0 licence is a shorter, simpler, and broadly permissive licensing agreement intended to enable wider sharing and usage of open data. It permits recipients to broadly use, analyse, modify and share data, and retains the explicit permission to use the results of any computational analysis of data without restriction or obligation.

The MIT License is popular for open-source software. The licence is permissive in nature and has very few restrictions around what users must, can, and can’t do when they use, modify, or redistribute the licensed code. Learn more

The foundations (or ‘freedoms’) of the GPLv3 licence are the ability to:

• use the licensed software for any purpose,
• change the licensed software to suit your needs,
• share the licensed software with others, and
• share the changes you make.

Releasing software as a free work under the GNU GPL means that it will stay that way, no matter who changes or distributes the program. This is known as ‘copyleft’ - the software is copyrighted, but instead of using those rights to restrict users (as with proprietary works), the GPL ensures that users have the freedoms noted above.

GPLv3 is compatible with the Creative Commons Attribution Share-Alike (BY-SA) 4.0 licence - only this specific licence and version, and the compatibility is one way. CC BY-SA 4.0-licensed materials can be added to GPLv3 projects, but Creative Commons licensing is not suitable for software. Other considerations may also apply.
