Thanks for your feedback !
It does not rely on JSON schema at all, the idea was to build a representation that binds together data structure, views and behavior in a self-contained way (like .xlsx does).
There are a few tools that do enable to link JSON schema to views, like react-jsonschema-form (https://rjsf-team.github.io/react-jsonschema-form/) but you need to manage them separately, and they usually do not propose a way to add the fields "methods" (which was the feature I found interesting to make "dynamic" spreadsheets).
That being said, I think the framework should clearly propose an export from Schema to JSON Schema or Yaml at some point, just as you should be able to start building your Schema by importing a JSON Schema (and although there might be some gray zones between the 2).
No, sorry, it's not yet open-source, and currently there are some strong links between Document and Workspace (Links, Files...) that would need to be more "abstracted" to make the builder an independent component. But I hear you point ! (and all the comments in this thread are raising the same ! :) )

2. Deserializing JSON into objects I knew for this project I'd have to deserialize GeoJSON into objects to work with them effectively in the app. Building this beast of a class felt quite daunting for being brand new to Dart and also for what was quite a complex GeoJSON file. However, I found an open source library called quicktype that generates strongly-typed models and serializers from JSON type scripts to a number of languages, including Dart. All you have to do is put in the JSON you want decoded, and it will return a prebuilt class that you can then use in your project. Quicktype have a handy website front end (https://app.quicktype.io/) for this - it worked first time and I was so grateful not to have to build this myself!

Project mention: typia (20,000x faster validator) challenges to Agentic AI framework, with its compiler skill | dev.to | 2025-03-25
typia and @agentica concenstrates and specializes on this concept, function calling to achieve the Agentic AI. Just looking at the definition of LLM function calling, it's such a cool concept that you wonder why it's not used. Wouldn't it be possible to achieve Agentic AI by listing the functions needed at that time?

Project mention: Gemini Robotics brings AI into the physical world | news.ycombinator.com | 2025-03-12
Google had really great products, that almost everyone I knew used, then they scrapped them for new shiny thing that competed. The one that angers me most is Google Talk, it used to work with any XMPP client, until it did not, and now its long since dead. They made their own version of tinychat (hangouts) and then mostly killed that too.
Obligatory overview of things Google has killed, because its easy to forget some of the gems:

Nice!
I've been using GOVUK stuff for my own purposes for a good-long while now, this should speed up the process.
I'll try to plug your thing into Json Forms [1], then I'll be back to the good old days .
