In the CC-BY-ND human readable summary, there is the sentence
Attribution — You must give appropriate credit, provide a link to the license , and indicate if changes were made. You may do so in any reasonable manner, but not in any way that suggests the licensor endorses you or your use.
I assume they want to express that it has to be indicated that changes to the license must be indicated. For me, when first reading the license, it seemed that I have to indicate whether or not I made changes to the product, which is a bit confusing, because ND means that you’re not allowed to make changes.
Does the comma make the difference in this case?
You are free to share the material
But you must
- give appropriate credit
- provide a link to the license
- indicate if changes were made
The three clauses all apply to “what you must do to be able to share the material” and “changes” in the third clause doesn’t refer back to “the license” in the second clause. I think the comma is in there to make that clearer, although the real clarification is a link to click on over “indicate if changes were made” that says:
In 4.0, you must indicate if you modified the material and retain an indication of previous modifications. In 3.0 and earlier license versions, the indication of changes is only required if you create a derivative.
