Thank you for your reply,
Sean.
If I may ask one last question of everyone:
Since asking my initial question here I've been told by our client that they've been told by Cerner that the Scheduling system is "read only" (which is how they said Cerner put it) and that no data could be written into it -- for example, to update an Appointment as 'Canceled' if/when a Patient called the Practice and either canceled or requested a reschedule.
If this is accurate, then would it be expected that any FHIR support (if it's present) would likely also be "read only" -- in other words, nly support queries and not writes/updates?
I apologize if that's a question that can't be answered other than a guess, but even an educated/informed guess can be helpful.
Thanks,
Thomas
