Good evening,

Emacs 24.4 and Org from Git.

Goal:

1) Visit every headline
2) If there is an ID property
   1) Then replace it's value with a UUID
3) If there is not an ID property
   1) Add an ID property and give it a UUID.

`org-uuid' [provides] the functionality to add the ID with a UUID.

[This post] explains how to do it:

┌────
│ (require 'org-id)
│    (save-excursion
│       (goto-char (point-max))
│       (while (outline-previous-heading)
│         (org-id-get-create)))
└────

What is the best way to do it with `org-element'?

  Using `org-element' here would be sub-optimal. Headlines are context
  insensitive, i.e., you don't need a parser to find one. 
  
  Anyway, the following should do:
  
    (dolist (p (nreverse
                (org-element-map (org-element-parse-buffer 'headline) 'headline
                  (lambda (headline) (org-element-property :begin headline)))))
      (goto-char p)
      (org-id-get-create))
  
  
  Regards,

    That works perfectly. Thank you.
    
    Tempted to run it in a on-save hook just to ensure that the document
    *always* has IDs. At least for tangle comments.

      You might try setting `org-id-link-to-org-use-id' to either t or
      'create-if-interactive.  I believe I have it set to t, and I get ids
      generated when I tangle.
      
      HTH,
      
      Sam
