DMN12 — Transitive information requirements maybe inferred from the spec text

  • Key: DMN12-225
  • Status: closed  
  • Source: Trisotech ( Denis Gagne)
  • Summary:

    Page 60 para 5 says:
    "As explained above, every information requirement at the DRG level is associated with a variable used at the decision
    logic level. Each variable that is referenced by a decision’s expression must be a variable referenced by one of the
    decision’s information requirements or an information requirement in the decision's requirement subgraph."

    Page 177 Glossary entry for "Requirement Subgraph" says:
    "The directed graph resulting from the transitive closure of the
    requirements of a DRG element; i.e., the sub-graph of the DRG
    representing all the decision-making required by a particular element"

    From these two entries one could erroneously infer that Information Requirement is transitive in nature. This creates serious concerns for BKMs and Decisions Services.

  • Disposition: Resolved — DMN 1.2
  • Disposition Summary:

    *Review text section 7.1 to remove potential misinterpretation of transitivity due to subgraph def and so it better reflects meta model *

    See revised text.
