Given this orders.json:

{
  "type": "struct",
  "fields": [
    { "id": 1, "name": "order_id", "type": "string", "required": true },
    { "id": 2, "name": "order_timestamp", "type": "timestamptz", "required": true },
    { "id": 3, "name": "customer_id", "type": "string", "required": true },
    { "id": 4, "name": "order_total", "type": "long", "required": true },
    { "id": 5, "name": "status", "type": "string", "required": true }
  ],
  "schema-id": 0,
  "identifier-field-ids": [1]
}

Run:

datacontract import iceberg --source orders.json

to produce the data contract:
