 The primary use case for JSON Schema is validation. Therefore it's imperative to understand precisely how the validation process happens. Let's take a little time to properly grasp the fundamental JSON Schema concept of Applicability.

 # Applicator keywords
 
 JSON Schema consists of many keywords. These keywords can be broken down into categories, one of which is "applicator". In the physical sense, an "applicator" is a thing you use to introduce one substance to another. For example, a cloth might be used to introduce polish to a nice wooden table. The cloth is the applicator. The polish is applied to the table via the cloth.

 A JSON Schema may be a Boolean or an Object. In the introductory article mentioned above, we noted how a Boolean Schema of `true` or `false` resulted in the same assertion result (true and false respectivly) regardless of the instance data. We also noted how the equivalent Object Schemas were `{ }` and `{ "not": { } }` respectively. (The `not` keyword inverts the assertion result.)

 When we talk about the whole Schema in terms of application, we usually refer to it as the "root Schema". This is because the other Schemas which are applied to specific instance locations are different, and we call them "subschemas". Differentiating between the root Schema and subschemas allows us to communicate with clarity which JSON Schema we're talking about, and when to use the Schema as part of the validation process.

 # Subschema application - Validating Objects and Arrays
 
 If your JSON instance is an Object or an Array, you'll likely want to validate the values of the Object or the items in the Array. In this introduction, you'll be using the `properties` and `items` keywords, and subschemas.

 The value of `additionalProperties` is not just a Boolean, but a Schema. This subschema value is applied to all values of the instance object that are not defined in the `properties` object in our example. You could use `additionalProperties` to allow additional properties, but constrain their values to be a String.
