An API call demonstrates connectivity. Interoperability is demonstrated when the receiver can actually use the information.

FHIR dominates Layer 02 (Structure), but terminology bindings dictate utility.

The message arrives; semantic equivalence does not. #HL7FHIR #HealthIT

An infographic from the Self Research Institute on a light grid background. A purple tag at the top reads "INTEROPERABILITY • FOUR LAYERS". The main headline states: "FHIR is a specification for exchanging healthcare information, not a guarantee of shared understanding," with the words "not a guarantee" highlighted in teal. Below are four stacked rows numbered from bottom to top. Row 04, Workflow, asks: "Can the receiver use it in a real decision or process?". Row 03, Terminology, asks: "Do codes, units, and value sets mean the same on both sides?". Row 02, Structure, is highlighted in dark blue and asks: "Does the payload use a recognized resource and field format?" with a teal tag identifying this layer as "FHIR'S STRENGTH". Row 01, Transport, asks: "Can one system securely send information to another?". A dark blue banner at the bottom reads, "THE MESSAGE ARRIVES; SEMANTIC EQUIVALENCE DOES NOT.". The footer contains the Self Research Institute name, website URL, and logo.
