Primitive properties

We will start by creating some primitive properties. Primitive properties are properties of a Digital Twin such as boolean, double, float, integer, string, and others.

We will extend the Floor model with two new properties.

Create a new version of the model file for a Floor by executing the following steps:

• Create a new folder called chapter5 under the Models folder of SmartbuildingConsoleApp. Right-click on the Models folder and select Add → New folder.
• Create a new .json file called floor.json in the chapter5 folder that contains the following code:

  {
    "@id": "dtmi:com:smartbuilding:Floor;1",
    "@type": "Interface",
    "@context": "dtmi:dtdl:context;2",
    "displayName&quot...
