[Draft] FHIR -> CCLF CLI

[jphechter]

Work outlined in: BCDA-4728

Proposed Changes

Some prospective BCDA users are unable to use our API as a data source due to limitations around ingesting FHIR data. Some others are hesitant to use BCDA as a data source due to an inability to compare the FHIR data against CCLF. This CLI converts FHIR data to a more familiar format that resembles data that would be found in the CCLF.

This tool serves 2 primary purposes:

• It is meant to act as a stopgap so that users blocked by FHIR data ingestion can immediately begin using BCDA as their data source
• It will allow users to verify the validity of the BCDA FHIR payload by reformatting to better match the CCLF files they are used to receiving

Change Details

• Create a command line executable created that parses for FHIR resources using provided params
• Establishes a means of parsing the provided FHIR data,
• Establishes reusable patterns to map this data to the CCLF format
• Sets up data mapping for CCLF 8, 9, and 7
• Stores output in appropriately named CSV files

Security Implications

• [X] new software dependencies
  • There are some Python dependencies that must be met in order for a user to use the CLI. Nothing directly affects the application.
• [ ] security controls or supporting software altered
• [ ] new data stored or transmitted
• [ ] security checklist is completed for this change
• [ ] requires more information or team discussion to evaluate security implications
• [ ] no PHI/PII is affected by this change

Acceptance Validation

• Verify setup instructions are accurate
• Verify the accuracy of output files

Feedback Requested

• This is a draft PR. No specific feedback requested at this time.
