It's actually quite easy
The web was created by adding hyperlinks (http://) in documents
The URI is the abstraction of the http: hyperlink
So, if you have another system to http (allowed and encouraged) you put those hyperlinks in your documents. In this case, JSON.
So add nostr: links in your json, or "nostr": <key> for example allows interop
And vice versa. This is all by design
