This example shows how to retrieve property meta data from 51Degrees on-premise device detection. This feature can be used to get information such as the category that a property belongs to or the possible values a property can have. (As of the current data file. If the data file is updated, the possible values for a property can change)

Expected output:

1 [List of properties with names and categories]
