 - Modify these data and write it back to disk.
 - Keep the original structure intact (indentation, spaces, format, ...).
 
-** Principles
-- Avoid any dependency outside of Python's standard library.
-- Don't do anything outside of the scope of parsing/re-serializing Org-mode files.
-- *Modification of the original text if there's no change is considered a bug (see [[id:7363ba38-1662-4d3c-9e83-0999824975b7][Known issues]]).*
-- Data structures should be exposed as it's read on Emacs's org-mode or when in doubt as raw as possible.
-- Data in the objects should be modificable as a way to update the document itself. *Consider this a Object-oriented design.*
 ** Safety mechanism

 produce unexpected changes on them. For this reason it's heavily recommended to
