# Get thing-definitions

> Returns the list of thing-definitions configured in the DPS.<br/>A thing-definition is the model of a connected product: it declares the metrics, alert-definitions, configuration-parameters, commands and dashboards shared by all the things based on it.<br/>Thing-definitions can inherit the elements of a super thing-definition and can be composed through the parent thing-definition, so as to model products made of several connected sub-systems.
