Licenses can get a little tricky when it comes to remixing resources. But don't stress! You may not even end up remixing, so this info will be moot. Even if you do end up remixing, you got this! We'll walk you through it.

Combining Materials

Remix refers to the ability to combine different resources together to create new derivative works. Creators of OERs often combine learning objectives from a variety of sources together, or add their own creativity to existing works to create a new educational resource that they in turn re-license openly. However, the legal terms of one license may not be compatible with the legal terms of another license.

Since each of the six CC licenses functions differently, resources placed under different licenses may not necessarily be combined with one another without violating the license term. If the material you are combining does not create an adaptation, they you may combine any CC-licensed content “as is” so long as you provide attribution and comply with any restrictions it applies. If you want to combine material in a way that results in the creation of an adaptation (i.e. a “remix"), then you must pay attention to the particular license that applies to the content you want to combine.

Recommendation:

At this moment the only thing you need to keep in mind is that if you end up remixing OERs, you should come back here and read the following information more carefully. Until then, skip ahead!
If you can't resist reading even just a little, consider just a quick perusal of the following info. Please don't get bogged down by this content!

Remixing Licenses: The Gory Details

The chart below shows which CC-licensed materials can be remixed. To use the chart, identify which CC licenses are attached to the materials you want to remix. Find the license for one on the left column and find the license type for the other on the top row. If there is a check mark in the box where that row and column intersect, then the works can be remixed. If there is an “x” in the box, then the works may not be remixed. Use at least the most restrictive licensing of the two (use the license most to right or down state) for the new work. If there's an "x" at the intersection of the row and column then you can not use these works. This probably indicates that one of the two licenses may not used for commercial purposes, or one of the licenses does not allow for derivative works to be created.

Important to notice these two generalities:

It is not possible to remix works where the first work is placed under a Creative Commons Attribution-Share Alike license and the second work is licensed under a Attribution-NonCommercial-ShareAlike license. The ShareAlike building block in first license requires that the newly created work is released under that license and can therefore be used commercially, the second license wants you to release the new work under a license that does not permit commercial use.
It is not possible to use in a remix where NoDerivative is a building block in processing a work. All works have been released under this License may only be distributed in their original form.
