Automatically adding licensing information for embedded content

[rczajka]

Problem

The plugin allows an author to set a license for her site or post, or insert a block with licensing info, by choosing from a set of CC licenses. There is also licensing information added to items in the media library, but no easy way to use that when embedding content.

Description

It would be useful to be able to add licensing and attribution information for embedded content (images, videos), based on this metadata in the media library, as automatically as possible, in an unobtrusive, but visible way.
This could be implemented as a block, which works just as regular media embedder, but also adds the layer licensing information.

Alternatives

The alternative is to accompany each instance of embedded content with a block with licensing information. This would mean the user has to always remember to provide the correct licensing information when embedding any image.

Additional context

Something similar (but not in a form of reusable plugin) is currently implemented on this site, under the orange (i) icon put on the embedded image:
https://centrumcyfrowe.pl/en/czytelnia/public-domain-your-raw-material-collages/

It will need to be checked for accessibility issues.

Implementation

• I would be interested in implementing this feature.

Question: is there a link available to a demo of this, or even screenshots?

I do think generally the block approach is better than the hover icon, because then the license information is instantly communicated and less likely to be missed, but I'm interested in seeing how you've designed this.

Hi,
You can now see a basic demo here:
