+        and updates the provided dictionary (`class_module_dict`) with a mapping of 
+        the class name to its module. If the `_module` key exists in `_schema_payload` 
+        (which was introduced in version 4 of openMINDS), its value is used as the module. 
+        Otherwise, the module is derived from the second-to-last component of the `_type`
