How is FHIR different from HL7?
FHIR builds on previous standards, including HL7 V2, HL7 V3, and CDA (Clinical Document Architecture—part of HL7 V3).

What is HL7 and why does it matter?
HL7 standards are healthcare-specific formatted messages that support a variety of system integrations and interoperability —and enable EHRs to communicate with a variety of systems that operate outside the EHR. Integrating the Healthcare Enterprise (IHE) is an initiative to improve how healthcare organizations share information.
