Is the https version of creativecommons.org an incorrect rights url?

[nicolasfranck]

If I put this url in the rights of my v3 IIIF manifest:

https://creativecommons.org/licenses/by-nc/4.0/

the JSON schema for v3 complains that this url isn't valid.
Apparently it should be http://creativecommons.org/licenses/by-nc/4.0/,
so with http instead of https. Is that stated somewhere that the
http versions should be used, or is this simply a missing validation rule?

Hi,

I'm afraid it does have to be http. The spec says:

"The value must be a string. If the value is drawn from Creative Commons or RightsStatements.org, then the string must be a URI defined by that specification."

and there is a long discussion in the following issue about which is the conical version and it was decided that http is for Creative commons:
