Thomas, Obvously you have put much deep thought into comparing these approaches. Many projects, especially the OIO project, will greatly benefit from your knowledge. Could you kindly educate us on the foundamental differences between "HL7 RIM" vs. "EHR Extract" vs. "EHR API" ? Thanks in advance, Andrew --- Andrew P.
