FYI, I’ve written a DEVONthink Notes to Tinderbox script that will take e.g. the annotation notes created by this script and transfer them to Tinderbox, including most of its metadata like tags, flag, rating, color & label and many custom metadata.
The script will set deep links to point back to your DEVONthink records (and PDF annotations), and can also recreate your note’s WikiLink connections as Tinderbox links.
