Predefined properties are user-facing key-value pairs that install with SystemLink and
SystemLink APIs.
You can call these properties in code and display their current values in the details area for
assets, systems, tags, and tests in the NI SystemLink Web Application.

Note
You cannot delete predefined
properties or modify how they act. If you create custom properties to interact with
SystemLink data services, verify that you are not referencing an existing property
to avoid name collisions.
