JSON Schema for tree structure

Question

I have to build tree like structure of Json data.Each node has an id (an integer, required), a label (a string, optional), and an array of child nodes (optional). Can you he

Answer 1

A schema for this structure only needs a definition of a node and a reference to that node. The property Children (renamed from Child) references the node as well.

Here's the schema:

{
  "$schema": "http://json-schema.org/draft-04/schema#",
  "$ref": "#/definitions/node",
  "definitions": {
    "node": {
      "properties": {
        "Id": {
          "type": "integer"
        },
        "Label": {
          "type": "string"
        },
        "Children": {
          "type": "array",
          "items": {
            "$ref": "#/definitions/node"
          }
        }
      },
      "required": [
        "Id"
      ]
    }
  }
}
