### Enumerations
Jackson support for Scala Enumerations defaults to serializing a `Value` as a `JsonObject` that includes a
field with the `"value"` and a field with the `"type"` whose value is the FQCN of the enumeration. Jackson
includes the [`@JsonScalaEnumeration`](https://github.com/FasterXML/jackson-module-scala/wiki/Enumerations) to
statically specify the type information to a field. When using the `@JsonScalaEnumeration` annotation the enumeration
value is serialized as a JsonString.
