OmniFocus data imported includes the notes' URLs ( to $URL) and sets the notes prototypes to the built-in 'Task'. The import uses the OmniFocus' task's key dates: Defer Until becomes $StartDate, Due becomes $DueDate, and Completed becomes $EndDate. Any mapped Date attributes unspecified in the impoerted data are set to a value of "never". If a task was completed before the present time, the note is marked as $Checked. If the task has a note, the text of the note is placed in the Tinderbox note's text.
