Aether

A command-line tool for processing FHIR healthcare data through configurable pipeline steps.

What Does Aether Do?

Aether helps you:

1. Extract patient data from a TORCH server using CRTDL query files
2. Pseudonymize the data using a DIMP service to protect patient privacy
3. Flatten FHIR data to CSV using SQL-on-FHIR ViewDefinitions
4. Send processed data to FHIR servers or DSF transfer systems
