In the JSON schema, what role does "IDS" serve?

In JSON, data is stored as key-value pairs. "IDS" in this context represents the key, which is a string that uniquely identifies the associated value. Keys are always strings and are followed by a colon, separating them from their corresponding value. For example, in {"IDS": "12345"}, "IDS" is the key, and "12345" is its value. "Object" is a collection of unordered key-value pairs, enclosed in curly braces. "Value" is the data associated with a key, which can be a string, number, boolean, null, object, or array. "Array" is an ordered list of values, enclosed in square brackets.
