What's the purpose of the data in the json field?

I can see that the JSON data is used when determing whether the element is a Video element, and hence needs the Video player.

Is there any guide to how to create the 'data' that is stored in the JSON?
It doesn't match the 2 API calls that are made. I assume it is generated inside the Keepicker element?

Indeed, the JSON is stored in order to determine the nature of the media during rendering and adapt the HTML component to use (image or video).
That being said, this behavior will evolve, and it is preferable for the moment not to use or rely on this JSON.
This JSON is constructed by the Keepicker, and for this, we rely on several API responses from our DAM.

It is complex to try to recreate this JSON.

What do you need?

Thanks keepeek_dam
We're working on a migration routine and want to ensure we create the elements correctly.
We have enough information now to continue so I will close this.
