A pretty simplified view of our object model, showing the structure of our relevant objects.  The speech system is omitted from this model, but is closely related to the PEDD (Portable Electronic Display Device, or “the wearable”).  Full details are available in our RAD.
	The Notes Database contains the user data, as well as the workorders and IETMs.  The workorders are mainly comprised of Stickies and annotations, and have pointers to relevant IETMs.  The PEDD has access to the workorders and IETMs via the Notes DB.
