Hey! I am studying the Croissant spec and I often study by writing Wikipedia pages on the matter; so I did that:
https://en.wikipedia.org/wiki/Croissant_(metadata_format)
(no one complained so far, and I think it is solid)
Anyways, would you have an open-license (CC-BY, CC-BY-SA or CC0) version of the summary image for Croissant that I could add to Wikipedia?
If its with clear licensed online, I can do it myself.
Cheers and congrats on the project
