Kinda difficult to explain as I dropped emacs due to issues with it on Windows despite enjoying org-mode.
The key thing is, org-mode treats data/text as a tree graph programmatically, you move through headings, and properties can be attached to those.
So a property for a deadline time can be added, and parsed, so you can get a list of todos/schedule showing the headline, and being able to jump to it.
Your api access targets these "nodes", so you are adding under "journal" rather than line 674 when using the template feature to quickly add entries.
emacs has ridiculous levels of customisation that let this data structure do basically what you want or need with some scripting.
