Perhaps with this knowledge you can identify if any gaps exist in the tools available. We may only need a little putty, that tool to collapse and expand json structures goes a long way.
From my own exploration I identified a number of mechanisms and methods we could use, but i dont yet have a full understanding of json, and possibly will not until i can explore json in tiddlywiki. A bit of a paradox really. I just need help getting over the hump.
I may just add we should do our best to empower the community and let them explore the design space rather than setting standards or developing opinionated solutions. Standards will most likely emerge from usage.
Also JSON being a standard along side javascript means it is possible to use vibe coding (sorry about the jargon).
