JSON Format For JavaScript

JSON Format Description

When user clicks the node on web page, frontend will automatically send a query to backend. Database will get information of the clicked node. The node's information is converted into a JSONObject and sent to server as a String by using jsonObject.toString() .

Format Structure

{
   “index0”: {
         “subject”: {
		“id”: ..,
		“group”: ..,
		“label”: ..,
		“level”: ..
		     }
         “predicate”: {
		“id”: ..,
		“group”: ..,
		“label”: ..,
		“level”: ..
		     }
         “object”: {
		“id”: ..,
		“group”: ..,
		“label”: ..,
		“level”: ..
		     }
    },
    “index1”: {
         “subject”: {
		“id”: ..,
		“group”: ..,
		“label”: ..,
		“level”: ..
		     }
         “predicate”: {
		“id”: ..,
		“group”: ..,
		“label”: ..,
		“level”: ..
		     }
         “object”: {
		“id”: ..,
		“group”: ..,
		“label”: ..,
		“level”: ..
		     }
    },
...
}

Using JSON in Java

To retrieve the id of the first object:

String id = jsonObject.getJSONObject("index0").getJSONObject("object").getString("id");

To retrieve the level of the second predicate:

int level = jsonObject.getJSONObject("index1").getJSONObject("predicate").getInt("level");

Using JSON in JavaScript

To retrieve the label of the first subject:

var jsonObject = JSON.parse(getJson);
var label = jsonObject.index0.subject.label

getJson is the JSON object which stored in server.

         “s”: {
            “id”: ..,
            “group”: ..,
            “label”: ..,
            “level”: ..
            }
    },
    “index1”: {
         “s”: {
            “id”: ..,
            “group”: ..,
            “label”: ..,
            “level”: ..
            }
    },
...
}

Using Top Level Concept JSON in JavaScript

To retrieve the label of the first node:

var jsonObject = JSON.parse(getJson);
var label = jsonObject.index0.s.label

getJson is the JSON object which stored in server.
