Proposed Class Diagram

Folder responsibilities:

• transportLayer/: Transport adapters and server launchers (e.g., REST, HL7 over MLLP).
• repositories/: Database providers and external data sources used by implementations.
• usecases/: Application use cases and orchestration logic.
• tools/: Shared helpers for decoding, validation, and normalization.

Setup (uv)

uv venv
uv add fastapi uvicorn

Run

$env:PYTHONPATH = "src"
python -m healthcare_sdk.app

Then open: http://127.0.0.1:8000/health

Install

pip install -e .

SDK Entry Point

The framework provides a registration helper to import arrays of components that implement the SDK Protocols.

from healthcare_sdk import register_components

components = register_components(
    adapters=[...],
    usecases=[...],
    validators=[...],
    decoders=[...],
    normalizers=[...],
    aihelpers=[...],
    storages=[...],
)

SDK Contracts

This document defines the generic envelope and component contracts for the SDK framework.

Envelope

The framework standardizes a generic envelope that can carry HL7v2, FHIR, or other protocols.

MessageEnvelope
  id: str
  protocol: str
  message_type: str
  raw_payload: str | bytes
  decoded_payload: dict | None
  normalized_payload: dict | None
  metadata: dict
  errors: list[ErrorDetail]
  status: str

Status values

• received
• decoded
• validated
• normalized
• stored
• error

Types

RawMessage
  id: str
  protocol: str
  raw_payload: str | bytes
  metadata: dict
  message_type: str | None

ErrorDetail
  code: str
  message: str
  stage: str
  context: dict | None

ValidationResult
  is_valid: bool
  errors: list[ErrorDetail]

Component contracts

Adapter
  executeServer(port=8000)
  receive() -> RawMessage

Decoder
  decode(raw_message: RawMessage) -> DecodedPayload

Validator
  validate(decoded_payload: DecodedPayload) -> ValidationResult

Normalizer
  normalizeData(decoded_payload: DecodedPayload) -> NormalizedPayload

Usecase
  execute(raw_message: RawMessage) -> MessageEnvelope

Storage
  save(envelope: MessageEnvelope) -> str
  connection() -> Any
  read(query: dict) -> dict
  delete(query: dict) -> bool
  update(query: dict, data: dict) -> bool

Errors

SdkError
  code: str
  message: str
  stage: str
  context: dict

DecodeError
ValidationError
NormalizationError
StorageError

Hl7 v2 examples

ALl the examples were taken of this repository

TO DO

• Definir tipo de entidades a se armazenar
• ORM?
• setup postgreSql to test
