This means that it will **always have a value**, it's just that sometimes the value could be `None` (or `null` in JSON).

        return OptionalThing.empty();

* <a href="https://json-schema.org/" class="external-link" target="_blank"><strong>JSON Schema</strong></a> (OpenAPI 자체가 JSON Schema를 기반으로 하고 있습니다)를 사용한 자동 데이터 모델 문서화.
* 단순히 떠올려서 덧붙인 기능이 아닙니다. 세심한 검토를 거친 후, 이러한 표준을 기반으로 설계되었습니다.
* 이는 또한 다양한 언어로 자동적인 **클라이언트 코드 생성**을 사용할 수 있게 지원합니다.

Zum Beispiel deklariert das obige Modell ein JSON "`object`" (oder Python-`dict`) wie dieses:

```JSON
{
    "name": "Foo",
    "description": "An optional description",
    "price": 45.2,
    "tax": 3.5
}
```

Da `description` und `tax` optional sind (mit `None` als Defaultwert), wäre folgendes JSON "`object`" auch gültig:

```JSON
{
    "name": "Foo",
    "price": 45.2
}
```
