ODK → FHIR via OpenFn

This recipe wires ODK Central submissions into the FHIR store using an OpenFn workflow and the ICR FHIR adaptor.

ODK Central  ──OData──▶  OpenFn (fhir-icr adaptor)  ──FHIR transaction──▶  FHIR store

The workflow has two steps:

1. Fetch — the odk adaptor pulls new submissions from ODK Central via OData, incrementally (a cursor on __system/submissionDate so each run only fetches what's new).
2. Transform + load — the @openfn/language-fhir-icr adaptor turns each submission into ICR-profiled FHIR and upserts it into the store in one idempotent transaction.

The transform, credential, form-by-form mapping, worked workflow.json, and Lightning deployment are documented in the dedicated adaptor section:

• FHIR-ICR adaptor — Overview — how it works + the ESPEN MDA form → FHIR mapping table.
• Setup & running — install, credential (GCP service account), local run, and the full ODK → FHIR workflow.json + Lightning deploy.
• Extending & adapting — add a form transform or target a different store/IG.
