SBVR14 — SBVR SE does not support the DateTime usage of subscripts

  • Summary:

    The Date Time Vocabulary specification contains several Definitions and Necessities that use subscripted terms, e.g.,

    Necessity: For each time interval(2) and each time interval(3) that finishes time interval(2), the duration of the time interval(1) that starts time interval(2) complementing time interval(3) is equal to the duration of time interval(2) minus the duration of time interval(3).

    time point1 to time point2 specifies time period

    Definition: time point(1) is the first time point of a time point sequence and time point(2) is the

    last time point of the time point sequence and there is a time point(3) that is just before time point(2) in

    the time point sequence and time point(1) through time point(3) specifies the time period

    Each case introduces a subscripted term that is used to denote the same ‘referent’ ‘thing’ elsewhere in the definition/necessity. In the Necessity, all the subscripts are introduced terms. In the Definition, time point(1) and time point(2) refer to placeholders in the verb concept wording being defined, but time point(3) is an introduced term. These introduced terms were patterned on a usage of subscripts in SBVR clause 8.5.2 that introduces similar “local names”. SBVR Annex C does not describe such usages. Without them, it is not possible to formulate these definitions and necessities in SBVR Structured English.

    Is it the intent of SBVR SE to support such usages? If yes, then SBVR Annex C needs wording to support them. If no, then DTV needs to convert these formulations to plain text.
