[X3D-Ecosystem] X3DUOM to Zod (StandardSchema.dev) to JSON schema

[John Carlson]

Here’s an apparent example of creating a JSON schema from a zod schema in
TypeScript from google search:

import { z } from "zod";

const PersonSchema = z.object({
name: z.string().describe('The name of the person'),
age: z.number().meta({ examples: [30, 45] }), // Use .meta() for complex
metadata
});

const jsonSchema = z.toJSONSchema(PersonSchema);

console.log(jsonSchema);
