V2 and FHIR

Similarities

Built around re-usable “chunks” of data

Strong forward/backward compatibility rules

Extensibility mechanism

FHIR Differences

Each chunk (resource) is independently addressable

More than messages Human readable required Extensions don’t collide,

are discoverable Modern tools/skills Instances easy to read Lighter, modern spec
