# POC Azure IOT Digital Twins modeling
**Unlock the Power of IoT with Azure Digital Twin Modeling**
### :crystal_ball: About
This proof of concept uses some components from the [Digital Twins Definition Language (DTDL)](https://learn.microsoft.com/en-us/azure/digital-twins/concepts-models) to build and maintain a simple product.
#### DTDL
> A model is similar to a class in an object-oriented programming language, defining a data shape for one particular concept in your real work environment. Models have names (such as Room or TemperatureSensor), and contain elements such as properties, telemetry, and relationships that describe what this type of entity in your environment does. Later, you'll use these models to create digital twins that represent specific entities that meet this type description.
> Twin type models can be written in any text editor. The DTDL language follows JSON syntax, so you should store models with the extension .json. Using the JSON extension will enable many programming text editors to provide basic syntax checking and highlighting for your DTDL documents.

"name": "deviceStatus",
"schema": "string"
},
{
"@type": "Command",
"name": "reboot",
"request": {
"name": "delay",
"schema": "integer"
