Data point

definition

A data point is a quantity that is extended with various pieces of process information, namely - A creation time (instant). This is the point in time when the data point was created, which is not necessarily the time for which it is valid. In the case of soft-sensors or forecasters, a data point might have been created ahead of time, in the case of a direct observation a data point might created at its time of validity (or at the end of its validity time interval) and in the case of an archived value the data point might have been created after the fact. - A validity time (temporal entity) which will be named "time stamp". The validity time is the instant or interval in time in which a specific quantity is in effect. For example a room temperature might be measured at 12:00, which means it is in effect at this very instant. A specific amount of energy might me expended within the time-slot between 12:30 and 12:45, which means that the energy observation is in effect during this time interval. - A location or topological association. For example, an observation might be taken in a specific room, a power avarage might have been measured by a specific meter, a forecast might be valid for a specific region or grid segment. This association is therefore not always a location.
