DMN14 — Improvement of Semantic Domains Specification

  • Key: DMN14-32
  • Status: open  
  • Source: Goldman Sachs ( Octavian Patrascoiu)
  • Summary:

    The definition of Semantic Domains / Types in 10.3.2 does not contain:

    • a metamodel
    • relationships between various types

    I propose adding a metamodel and the following two relationship:

    1. Conforms To
    A semantic domain T1 conforms to a semantic domain T2 when an instance of T1 can be substituted at each place where an instance of T2 is expected.

    2. Equivalent To
    A semantic domain T1 is equivalent to a domain T2 iff they have the same name and the corresponding embedded semantic domains are equivalent. (e.g. List<Number> is equivalent only to List<Number> not List <String>).

    The above relationships should be defined via tables, similar to the ones used to describe the semantics of logic operators (page 119 Table 38).
