| - We define an observation, as a concept, to be more general than the concept of a measurement. Informally, observation refers to the result of recognizing or noting some fact or occurrence (Websters 1996). In Figure 7, we define the relationship ''itemObserved'' to refer to such an object noted by an observation, which are defined as either properties of some observable entity, or to the existence of an observable entity itself. A measurement goes further by assigning a value to an observed property. |
