Standards

We do not invent protocols. We adopt them and make them pleasant.

Standard	Role
FHIR R4	The resource model. Patients, encounters, observations, bundles.
SMART on FHIR	Launching apps inside clinical systems with the right context.
FHIRcast	Keeping several apps looking at the same patient at the same time.
FHIR Messaging	Event-driven exchange between systems.
OAuth 2.0 / OpenID Connect	Who you are, and what you are allowed to see.

Servers

Any conformant FHIR server. The primitives are tested against open implementations first.

Conformance over cleverness. Profiles over forks. Read the spec, then read it again.
