Is it possible to go the other way after a successful Json to Kotlin conversion, ie. Kotlin to Json?

This lib is cool. Just curious if it's possible to go reverse?

Start with some sample.json data:

{
  "title": "Lorem ipsum",
  "date": 1500137916,
  "validity": false
}

Create a schema from it: quicktype sample.json -l schema -o schema.json

{
    "$schema": "http://json-schema.org/draft-06/schema#",
    "$ref": "#/definitions/Schema",
    "definitions": {
        "Schema": {
            "type": "object",
            "additionalProperties": false,
            "properties": {
                "title": {
                    "type": "string"
                },
                "date": {
                    "type": "integer"
                },
                "validity": {
                    "type": "boolean"
                }
            },
            "required": [
                "date",
                "title",
                "validity"
            ],
            "title": "Schema"
        }
    }
}

Then quicktype -s schema schema.json -o Model.kt to get a Kotlin file.

// To parse the JSON, install Klaxon and do:
//
//   val model = Model.fromJson(jsonString)

package quicktype

import com.beust.klaxon.*

private val klaxon = Klaxon()

data class Model (
    val date: Long,
    val title: String,
    val validity: Boolean
) {
    public fun toJson() = klaxon.toJsonString(this)

    companion object {
        public fun fromJson(json: String) = klaxon.parse<Model>(json)
    }
}

I suspect it's not supported, but I'd like to be able to add a new property to the Kotlin file and have this flow in reverse, back to say the schema.json file.

You may be able to use the Jackson json-schema module, it takes Java POJO's and converts them to JSON schemas:
