  • Nigel Davis  Draft temporal expression document
  minControl modelND, MB

Briefing on the control model off-line discussion

Nigel reported that he and Malcolm had an exporatory dicussion on the control model. Started from a broad scope, then identified the areas to be focussed on.  Agreed on the list of headings with bullet items within each. Wil have another off-line discussion next week.

  minEquipment modelKL, ND

Equipment property modeling - To change from composite to decorate.

Reason of changing from composite to decorate:

  • Many equipment properties depend on the equipment type. Such as conditionality, present or not, full/partial range, threshold strategy, etc.. These properties could not be determined at the model design stage. Thus, these properties should not simply be modeled by using the composition approach (as currently shown in v1.5,  although they are marked as Expperimental). 
  • Consider using the Spec approach to decorate the base classes (Equipment, Holder and ManufacturedThing) with the relevant properties.
