Smile Digital Health (formerly Smile CDR) is a Toronto-based health interoperability software company and the commercial steward of the open source HAPI FHIR project — the world's most widely deployed Java implementation of the HL7 FHIR standard. Its flagship platform, Smile CDR (marketed under the Smile Omni portfolio as the OmniVera Health Data Platform), is a FHIR-native clinical data repository and integration engine that ingests HL7 v2.x, CDA, CSV, JSON, XML, and FHIR payloads, normalizes them to FHIR (R4, R5, STU3, DSTU2), and exposes them through a hardened FHIR REST API, SMART on FHIR / OAuth2 / OIDC, Bulk Data, Subscriptions, MDM, Terminology Services, CQL-based Quality Measures, and a JSON Admin API.
