8.2 WIA 4-Phase Architecture

The WIA-MEDICAL-DRONE-DELIVERY standard implements the WIA 4-phase architecture pattern, providing structured layers for data management, API access, protocol definition, and system integration.

Architecture Philosophy

The 4-phase architecture separates concerns into distinct layers: Phase 1 (Data) defines the information model, Phase 2 (API) provides programmatic access, Phase 3 (Protocol) enables communication, and Phase 4 (Integration) connects with existing systems. This separation enables flexibility while maintaining consistency.

Phase	Name	Purpose	Components
Phase 1	Data Layer	Information modeling and storage	Aircraft, flights, cargo, deliveries
Phase 2	API Layer	Programmatic access and operations	REST APIs, WebSocket, authentication
Phase 3	Protocol Layer	Communication and data exchange	Message formats, telemetry, C2
Phase 4	Integration Layer	External system connectivity	EHR, UTM, inventory systems

Integration Patterns

System	Integration Method	Data Exchanged
Hospital EHR	FHIR R4, HL7v2	Orders, delivery confirmation
Blood Bank	ISBT 128, API	Blood orders, tracking
UTM/U-Space	USS APIs	Flight authorization, deconfliction
Remote ID	ASTM F3411	Broadcast identification
Weather Services	API	METAR, TAF, forecasts
Inventory Systems	EDI, API	Stock levels, orders

UTM Integration

Integration with UAS Traffic Management systems enables airspace authorization:

Flight Plan Submission: Submit intended operations
Authorization: Receive airspace clearances
Conformance Monitoring: Report actual vs. planned
Conflict Resolution: Respond to deconfliction

Start with Phase 1 data model implementation
Build APIs incrementally based on use cases
Implement healthcare integrations using standard protocols (FHIR, HL7)
Ensure UTM integration from initial deployment
Design for scalability and multi-operator scenarios
