As an FHIR service provider, I want to generate structured FHIR resources for each health record type (e.g., Observation, Condition, Procedure), so that I can prepare them for inclusion in a standardized FHIR Bundle.

Details/Implementation Notes:

• Use hapi-fhir-structures-r4 to create resource classes.
• Standard drug codes (SNOMED CT) to be used where applicable.
• Resource types depend on record
  • Immunization → Immunization
  • OP → Condition, MedicationRequest, Procedure
  • Diagnostics → DiagnosticReport, Observation, Binary
• Binary resource can be used for scanned files (e.g., prescriptions).

Acceptance Criteria:

• FHIR resources generated in R4 structure.
• Each resource must contain valid minimal fields (e.g., subject, status, code).
• Option to include binary content in base64 format for scanned documents.
