You are building a smart building solution using Azure Digital Twins. You need to model the physical hierarchy: Building → Floor → Room → Sensor. Each room must know its current temperature from its sensors. Which Azure Digital Twins concept represents this hierarchy?

Question

Sunny · Accepted Answer

Create separate DTDL models for each entity type and use DTDL Relationships to link them. Azure Digital Twins uses DTDL (Digital Twins Definition Language) to define models. Each entity (Building, Floor, Room, Sensor) is a separate DTDL model. Relationships in DTDL link instances together, creating a navigable graph that mirrors the physical hierarchy. This enables graph queries across the entire building model.
