Chapter 8: WIA-MEDICAL-DRONE-DELIVERY Standard

8.1 Standard Overview

The WIA-MEDICAL-DRONE-DELIVERY standard provides a comprehensive framework for implementing autonomous medical logistics systems. Built on the WIA 4-phase architecture (Data, API, Protocol, Integration), this standard enables interoperability between healthcare systems, drone operators, and regulatory infrastructure.

Guided by the principle of 弘益人間 (Hongik Ingan) - "Benefit All Humanity" - this standard aims to bring life-saving medical supplies to every corner of the world through innovative aerial logistics.

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.

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

The Integration Layer connects the drone delivery platform with external 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
