  • Root
  • encourage people to review and leave comments on the wiki page
  • the yellow classes are temporary and will be replaced by actual classes once the proposal is considered stable
  • green attributes are redefined from the root (the cardinality is changed)
  • suggest to give some use cases for different classes (e.g., domain, place, etc.)
• VES model
  • suggest to change IM design (not to simply reverse engineering on the DM)
  • suggest to simplify the model not to show all the details
    • how to utilize Papyrus to show the details?
      • IISOMI is working on tools to relate IM with YANG, etc., but not show the details
      • ITU, IETF are working on some tools as well
    • the level of details to show needs more discussion
  • want to model the associations between particular metrics (VES events, etc.) with the objects provided them (e.g., PNF provide some specific metrics)
  • next step: expect more comments on the wiki page, may have further calls/discussions on that, present the proposal to larger audience
