<div dir="auto">There may be a point of confusion between X3DJSONLD.js (and other languages) and the rest of X3DJSONLD. The former is the JSON to DOM document load and export class. There are additional parts of X3DJSONLD which start with the JSON encoding and produce SAI compatible language binding examples: In the past these were reliant on X3DJSAIL, but I’ve been working on a new x3djsonld.py which skips the DOM step and relies on x3d.py, and is still pretty much a WIP.</div><div dir="auto"><br></div><div dir="auto">To be clear, X3DJSONLD will probably never be SAI, except as a way to load JSON into a scenegraph, a single, uninteresting method or two.</div><div dir="auto"><br></div><div dir="auto">If you are interested in developing a JavaScript/ECMAScript/TypeScript SAI, I suggest you look at my es6x3d repository on GitHub.

Tools are starting to fail behind the drafts of the JSON schema standards, for example, there is no Java implementation of the 2020-12 draft that I know of.

<br>
While .gltf is also valid JSON, using a generic .json extension for<br>
them feels "unnecessarily generic". It would be like using .xml<br>
instead of .x3d for models in X3D XML encoding.<br>
<br>
That being said, why do you validate with X3D JSON schema all *.json?<br>
Shouldn't X3D JSON also have a specific extension, not use generic<br>
.json?<br>
