Re-dated items

The following are proposed dates for the past actions. The action list has been updated to reflect this. The actions can be reverted/adjusted as necessary. Only actions that have been moved are listed.

Note that now provided in the bullet under each action item is the link to the source minutes that created the action item.

  • Nigel Davis  Draft temporal expression document
  • Nigel Davis  To blend TAPI model of streaming with the Core model
  • Hing-Kam Lam Nigel Davis   To rebuild the equipment property model. To change from composite to decorate. 
  • Nigel Davis   Discuss the intent grammar, spec grammar. Explore mechanism converting explicit property sentence into constraint statements.
  • Nigel Davis   Discuss with the TAPI and Wireless transport: Moving away from simple packaging, e.g., object class, datatype, to a much deeper structure. This will not work with the uml2yang tool. Therefore the model will need to be refactored into object/datatype for uml2yang tool.
  • Nigel Davis  To look for an example that is more robust and compelling on the need of a separate occurrence.
55 minTemporal expressionND

Temporal expression model examples (ND)

  • CH showed (from ONF_T73)
    •  
      • ND: Will show how the Temporal Expression model works for the above example. 

ND introduced

  • The Papyrus instance diagram on the right shows how the Example (on the left) is repressed.
  • CH: PhasingPeriodTe: why Real rather than Integral
    • ND: Thought to allow shift/offset. Will change from Real to Integer.
  • AM: In the comment of BoundingPeriodTe, periodInDay should be periodDurationInDay
  • AM: To formalize the combination of Union and Intersection. There are some YANG expressions on Union and Intersection that could be considered/referred. Conventaton diagram.
    • CH: At least in documentation, such as tables showing how they are combined, explicit/implicit applied.
    • SM: xpath when statement
    • ND: Could discuss in IISOMI (Feb. 11)
  • AM: PhasedPeriodTe: wonder if periodDurationInMinutes is necessary. Any use case or example? Not duration but event time (the moment). 

ND: Allow the freedom of decorate/augment
