Schema

Here is a basic example of a JSON Schema:

 {
	   "title": "Example Schema",
	   "type": "object",
	   "properties": {
	       "firstName": {
	          "type": "string"
	       },
	       "lastName": {
	          "type": "string"
	       },
	       "age": {
	          "description": "Age in years",
	          "type": "integer",
	          "minimum": 0
	       }
	   },
	   "required": ["firstName", "lastName"]
 }
