    Name of the property as visible to catalog users. All properties are top-level within the properties object within a catalog spec.
  - typeName
```
String typeName()
```
    The name of the type of this property to be displayed in error messages.
  - validate
```
void validate(Object value,
              com.fasterxml.jackson.databind.ObjectMapper jsonMapper)
```
    Validates that the object given is valid for this property. Provides the JSON mapper in case JSON decoding is required.
  - merge
```
Object merge(Object existing,
             Object update)
```
