It links to a sensor to describe what made the observation, and to the observed feature, property, property of interest, state, or state of interest. Typically, its result is a property value or a state. An observation of a state (OP coswot:observes) should have a state as a result (OP coswot:hasResult). Respectively, an observation of a property should have a property value as a result."@en ;
