SBVR11 — "Projection" Needs to Be Renamed

  • Key: SBVR11-135
  • Legacy Issue Number: 16524
  • Status: closed  
  • Source: Business Rules Group ( Ronald Ross)
  • Summary:

    Problem Statement: "Projection" is currently defined in Clause 9.3 to be a semantic formulation. This usage of the term is counterintuitive for several reasons.
    (1) Semantic formulations are a way of structuring meaning particular to SBVR.
    (2) "Projection" can be used to mean the 'process' of projecting, rather than the result of projection, as usually preferred in SBVR.
    (3) "Projection" should be included in SBVR under its appropriate real-world meaning.

    Resolution:

    1. Change each instance of "projection" in Clause 9.3 to "projecting formulae"

    2. Inspect every other instance of "projection" in SBVR to determine whether it refers to "a projecting formulae" or to the process of projection ("projecting"), and adjust accordingly.

    3. Add a real-world concept and definition for "projection" and for "bag" as currently used in "bag projection". (It needs to be determined where in SBVR this entry should be included.)

  • Disposition: Resolved — SBVR 1.1
  • Disposition Summary:

    SBVR is clear that a ‘projection’ is a kind of semantic formulation and uses the term consistently. “Bag projection” has a formal definition in SBVR that is unambiguous as it is. Since there is no ambiguity within the SBVR specification or no significant likelihood of misinterpreting the SBVR specification based on a different widely-used meaning for the term, making such a wide-spread change is not justified.
    Any problems regarding another meaning for “projection” not being included in SBVR requires a separate Issue stating how the SBVR specification is broken.
    Revised Text:
    No change.
    Disposition: Closed, No Change Required
