Proposal for JSON Transform serialization. With possibility to expand to other Entity data.

KuratorSerializeEntity.cs

using System;
using System.Collections;
using System.Collections.Generic;

using UnityEngine;

namespace KuratorCore.Serialize {

	[Serializable]
	public class KuratorTransform {
		public Vector3 localPosition;
		public Quaternion localRotation;
		public Vector3 localScale;
	}

	public class KuratorSerializeEntity : MonoBehaviour
	{

		private Transform transform;
		private KuratorTransform kTransform;

		void Start()
		{
			transform = gameObject.GetComponent<Transform>();
			kTransform = new KuratorTransform();

			updateTransform();

			Debug.Log(getCurrentTransformAsJson());
		}

		void updateTransform() {
			kTransform.localPosition = transform.position;
			kTransform.localRotation = transform.rotation;
			kTransform.localScale = transform.localScale;
		}

		string getCurrentTransformAsJson() {
			updateTransform();
			return JsonUtility.ToJson(kTransform);
		}

		void Update() { }
	}
