Standards
The interoperability standards primer
HL7, FHIR, GS1, and UDI in plain language — what each one does and where it fits.
HL7 & FHIR
The messaging standards that move clinical data between systems. HL7 v2 is the workhorse of bedside and lab data; FHIR is the modern, API-first successor.
GS1
Global identifiers for products and locations — the GTIN that gives every item one name everyone agrees on.
UDI
Unique Device Identification — the FDA framework that puts a scannable, registered identity on every medical device.
