KERML_ — isPortion, semantics

Open Closed All
  • Key: KERML_-6
  • Status: closed  
  • Source: NIST ( Mr. Conrad Bock)
  • Summary:

    Portion features (Feature::isPortion=true) are described as

    Portion features are composite features where the values cannot exist without the whole, because they are the “same thing” as the whole. (For example, the portion of a person's life when they are a child cannot be added or removed from that person's life.)

    but this semantics is not math/modeled, at least not in Core, which does not include models of time or space. A syntactic constraint that isPortion implies isComposite also seems to be missing.

    The FTF considers this issue to have merit, but, due to lack of time, is deferring it to a future RTF.
