Digital Twin Models and Static Properties

The static properties enumerated by a Digital Twin model represents IoT data that typically doesn’t change.

In my last two posts about defining Digital Twin models for your IoT system, I described “telemetry properties” that map 1:1 with device sensors and their associated data types and units of measure. I also described “virtual properties” that are a sort of “soft sensor” whose value is derived through a calculation from sensor values and other data sources.

Today I’m adding “static properties” to your Digital Twin model which are values that typically don’t change. If I use a car as an example, static properties could be things like the length of the car, the number of cylinders, displacement of the engine, and the volume of room in the trunk. Static properties are necessary to have a more complete view of the actual entity (car in this case) and to be used as reference data for analytics when defining the Digital Twin model that instances of Digital Twins will be derived from.
