Discussion of Naming


Although ``history'' usually has to do with past events (-E5), its use for the future—as introduced by prophecies, science fiction, scientific forecasts—does not seem to present comprehension difficulties. (The adjective ``historical'' seems more problematic for some.) Talking about future history, requires the same extension of meaning as required by talking about future data.

The alternative term ``temporal value'' is less general, since it applies when ``history'' specializes into attribute history (value history). Moreover, ``history'' is a slightly more general concept than ``time sequence'': different time sequences (with different time granularities) could be extracted from the same history. Therefore the definition of ``history'' does not prevent defining ``time sequence.''

``History'' is also preferred over alternative names because it allows a better definition of related terms. Since it implies the idea of time, ``history'' does not require further qualifications as ``sequence'' or ``series'' do (+E2). In particular, ``history'' well lends itself to be used as modifier (+E1), even though ``time sequence'' is an alternative consolidated term (-E3,-E6).

``History'' is natural (+E8) and precise (+E9), whereas ``temporal value'' may recall a temporal element (e.g., timestamp value) and ``time sequence'' may recall a sequence of temporal elements.
