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; e.g., it seems the V3 negation indicator resulted from an overzealous commitment to this principle) (agreed)
      3. design guidance:
        1. avoid Boolean negation in information models (agreed)
        2. avoid negation in unary code patterns (sounds good but we don't have a clear foundation for it)
  2. Options for ensuring coverage of use case list
    1. Wider audience
      1. Jay to send out agenda & attendance reminders
    2. Review of assets for additional cases
      1. WG list (Rob)
      2. FHIM domains (Jay)
      3. openEHR (Gerard)
      4. Ontologist experts: BSmith, WCeusters (Gerard)
      5. IHTSDO (Richard)
  3. Is the use case application list useful (to enumerate not just content to represent, but contexts that may have divergent requirements)
    1. GF: UI is only outlier
    2. RH: different implementers may want to decompose at different points
    3. Yes
  4. Scenario patterns: useful?
    1. Probably
