Question: how is fhir different from hl7?
Answer: FHIR stands for Fast Healthcare Interoperable Resource. FHIR combines the best features of HL7 V2, HL7 V3, and CDA, while leveraging the latest web service technologies. The design of FHIR is based on RESTful web services. This is in contrast to the majority of IHE profiles which are based on SOAP web services.
