HTTP Import

Downloads FHIR NDJSON files from an HTTP/HTTPS URL.

Configuration

pipeline:
  enabled_steps:
    - http_import

Usage

aether pipeline start aether.yaml crtdl.json https://example.com/fhir/Patient.ndjson --allow-http-crtdl

Notes

• Every aether pipeline start invocation requires a CRTDL JSON as the second positional argument, even when the import URL already points at the data — the CRTDL is used by downstream steps such as flattening.
• The HTTP(S) URL is provided as the third positional argument and overrides any local-import configuration.
• HTTP import bypasses TORCH's CRTDL guarantees, so aether refuses the run unless you opt in with --allow-http-crtdl. Pass the flag to acknowledge that the downloaded data may not match the CRTDL query.
• Both HTTP and HTTPS URLs are supported; downloads land in the job directory.
