Minutes

Minutes/Conclusions Reached:

  1. Motion from Montreal
    1. We found the following embedded in the motion(s):
      1. requirements: avoid counterintuitive semantics, intractability (hence, BL not a good idea in information model or semantics) (agreed)
        1. It may be possible to address semantic issue with DL independently of information modeling.
      2. principles: consistency (if we clarify boundaries) (agreed)
      3. design guidance:
        1. avoid Boolean negation in information models (agreed)
        2. avoid negation in unary code patterns (unclear)
