+#### Serialize/Deserialize Data In Free Form
+
+While DTO objects apply strict rules on data ser/de, you can also
+serialize/deserialize data in free form using type `oatpp::Any`.
+
+```cpp
+oatpp::Fields<oatpp::Any> map = {
+  {"title", oatpp::String("Hello Any!")},
+  {"listOfAny",
+   oatpp::List<oatpp::Any>({
+     oatpp::Int32(32),
+     oatpp::Float32(0.32),
+     oatpp::Boolean(true)
+   })
+  }
+};
+
