TBDTAPI 2.0 Github IssuesTo-be-removed

General Areas to be worked on (at least 1 item per week should be scheduled in TAPI call - a brief contribution should be provided)

  • UML Lifecycle sterotypes - capture maturity of TAPI classes/attributes explicitly - no stereotype means "not determined"
  • Entity Lifecycle - (Lifecycle/Operation/Administrative state enumerations): need more explanation, documentation and inter-state-dependency diagrams
    • Some state diagrams are available in Core IM 1.3 Foundation module (512.3 figures 3-4, 3-5, 3-6 & table 16)
  • Topology pacs: need develop descriptions/examples how that can be used
  • Some of the attribute types should be extensible enumerations instead of string (e.g. address-type, cost-name)
  • Termination pac (State/Direction) - needs discussion on usage or even if we need them
  • Generalized Capacity data structure
  • OTIM- OCH & OTSi usage clarification from ITU-T SG15
  • Extensible Enumerations - should all TAPI enumerations be extensible by default ?
    • Semantic v/s vendor/interface/run-time extensible
  • Backward compatibility
  • NMDA compatibility
  • Multi-vendor Inter-operability gaps
    • Can it be addressed by development guide/guidelines?
