 Sharkitek defines some basic types by default, in these classes:
 
+- `BoolType`: boolean value in the model, boolean value in the serialized object.
 - `StringType`: string in the model, string in the serialized object.
 - `NumericType`: number in the model, number in the serialized object.
 - `DecimalType`: number in the model, formatted string in the serialized object.
+- `DateType`: date in the model, ISO formatted date in the serialized object.
 - `ArrayType`: array in the model, array in the serialized object.
 - `ModelType`: instance of a specific class in the model, object in the serialized object.

 following a certain naming convention: "S{type_name}".
