 ## The schema format
 The Schema supports multiple types: 
 
-* Primitive types: `string`, `number`, `boolean`
+* Primitive types: `string`, `number`, `boolean`. We can remove schema format of `Primitive types` since is no need to reconstruct them.
 * Built-in object types: `Date`, `BigInt`.
 * Built-in collections: `array`, `map`
-  * Arrays need to be declared as `{array: {value: valueType}}` 
-  * Maps need to declared as `{map: {key: 'keyType', value: 'valueType'}}`
+  * Arrays need to be declared as `{array: {value: valueType}}`, there are no reconstruct for `Primitive types`, for the value type is `Primitive types`, we can remove this field.
+  * Maps need to declared as `{map: {key: 'keyType', value: 'valueType'}}`, there are no reconstruct for `Primitive types`, for the key and value type are `Primitive types`, we can remove this field.
 * Custom classes are denoted by their name, e.g. `Car`
-* Near SDK Collections (i.e. `Vector`, `LookupMap`, `LookupSet`, `UnorderedMap`, `UnorderedSet`) need to be declared as `{class: ClassType, value: ValueType}`
+* Near SDK Collections (i.e. `Vector`, `LookupMap`, `LookupSet`, `UnorderedMap`, `UnorderedSet`) need to be declared as `{class: ClassType, value: ValueType}` if we need to reconstruct value or we can simplify to mark `ClassType` if we no need to reconstruct value for `Primitive types`.
