Understanding Open Licenses
Most works are protected by copyright automatically upon their creation (e.g. images, videos, audio, written texts), which restricts how the work may be used (e.g. it cannot be copied or redistributed without the consent of the creator, except in very specific circumstances that are exceptions to the copyright).
An open license allows a creator to share their work more freely with others and allows the re-use and redistribution of that work with few or no restrictions. Creative Commons is the most well known and widely used form of open licensing.
Creative Commons Licenses
Creative Commons licences are standardised tools that provide a range of options for creators who are interested in sharing their works with the public rather than reserving all rights under copyright. Creative Commons works are free to use provided the licence terms are followed.
The four licence elements—BY, SA, NC, and ND—combine to make up six different licence options.
All of the licences include the BY condition, which requires that the creator be attributed in connection with their work. Beyond that commonality, the licences vary whether (1) commercial use of the work is permitted; and (2) whether the work can be adapted, and if so, on what terms.
The six licences, from least to most restrictive in terms of the freedoms granted reusers, are:

Implications for OER
- If you wish your work to be more widely available, consider applying a Creative Commons license. Carefully consider the options available when determining which is the best for your situation. You can find more information about choosing a Creative Commons license in the JCU OER Author Guide.
- You must acknowledge the creator and include the license information when you use a resource licensed under Creative Commons
- If you are combining several elements together to make a new resource, you must consider any licensing that applies to those individual elements and whether or not they are compatible. You can find out more about the compatibility of license types in the JCU OER Author Guide
