What are the steps to designing a unique JSON data format?

When working with a JSON data structure containing 100 objects, the output will resemble the following:

[{
    "Value": "Sens1_001",
    "Parent": Null,
    "Child": {
        "Value": "Sens2_068",
        "Parent":"Sens1_001",
        "Child" : {
            "Value": "Sens3_034",
            "Parent": "Sen2_068",
            "Child": null,
            "z_cordinate": 5
                  },
        "z_cordinate": 0
            },
        "z_cordonate": -5
    },
{
    "Value": "Sens1_002",
    "Parent": Null,
    "Child": {
        "Value": "Sens2_037",
        "Parent":"Sens1_002",
        "Child" : {
            "Value": "Sens3_099",
                              "Parent": "Sen2_037",
                              "Child": null,
                              "z_cordinate": 5
                   },
             "z_cordinate": 0
             },
  "z_cordonate": -5
},
{
   "Value": "Sens1_003",
    "Parent": Null,
    "Child": {
        "Value": "Sens2_012",
        "Parent":"Sens1_003",
        "Child" : {
            "Value": "Sens3_054",
            "Parent": "Sen2_012",
            "Child": null,
            "z_cordinate": 5
                  },
        "z_cordinate": 0
             },   
        "z_cordonate": -5
},
.
.
. // until the 100th object
{
    "Value": "Sens1_100",
    "Parent": Null,
    "Child": {
        "Value": "Sens2_001",
        "Parent":"Sens1_100",
        "Child" : {
            "Value": "Sens3_021",
            "Parent": "Sen2_001",
            "Child": null,
            "z_cordinate": 5
                  },
    "z_cordinate": 0
             },
    "z_cordonate": -5
}]

PLEASE NOTE: I have modified the appearance of the objects to look more like an array rather than individual objects. While JSON is important, the array format better serves my purpose.

Objective:

I am looking for guidance on how to access the objects in a X.parent.child hierarchy. I have some understanding but need assistance in structuring this object properly. Additionally, I intend to access the objects in both directions, from Grandparent to Parent to Child and from Me to Parent to Grandparent. It's crucial that the parent-child relationships are logical and not random, especially since a parent can have multiple children.

If every 'value' key is unique, you can use it as the dictionary key. Here is a suggested design:

{
 "Sens1_001": {
               "value": "Sens1_001",
               "parent": null,
               "child": "Sen2_068",
               "z_coordinate": 5
              },
 "Sens2_068": {
               "value": "Sens2_068",
               "parent": "Sens1_001",
               "child": "Sen3_098",
               "z_coordinate": -5
              }
 .
 .
 .
}

Once this dictionary 'dict' is set up, if you have the value of the grandparent, you can access them like this:

grandparent = dict[value];
parent = dict[grandparent[child]];
child = dict[parent[child]];

Likewise, if you know the child's value,

child = dict[value];
parent = dict[child[parent]];
grandparent = dict[parent[parent]];

Let me know if you need further clarification.

Json, being a type of JavaScript array, allows you to access json objects similar to accessing an array:

<script>
  var json = [
        {'ID' : 1, 'parent': 'I am parent 1', 'child' : 'I am child'}, 
        {'ID' : 2, 'parent': 'I am parent 2', 'child' : 'I am child'}, 
        {'ID' : 3, 'parent': 'I am parent 3', 'child' : 'I am child'}, 
        {'ID' : 4, 'parent': 'I am parent 4', 'child' : 'I am child'}        
      ]
  console.log(json[0]);
  console.log(json[1].parent);
  console.log(json[3]['child']);
</script>

Knowing the index allows you to easily access any property of that object.
