• Agenda bashing
  • reminder for filling R9 high level requirements: https://wiki.onap.org/display/DW/ONAP+R9+Modeling+High+Level+Requirements
• Joint call with use case realization team
  • R9 use case & requirements: https://wiki.onap.org/pages/viewpage.action?pageId=99681185
  • schedule of use case realization call: https://wiki.onap.org/display/DW/Use+Case+Realization+Meeting+Register+MoM
  • major use cases of ONAP: https://wiki.onap.org/display/DW/ONAP+Major+Use+Cases
  • next step:
    • Ben will help invite use case owners to have a presentation in the following modeling calls
• Model Proposals
  
  • ETSI support for CNF model
    • R9 DM proposal: https://wiki.onap.org/pages/viewpage.action?pageId=93011772
      • aligned with SOL001 v4.2.1, package format is still under discussion
      • will ask for approval after SOL001 v4.2.1 is stable
    • a proposal of updating the information model documentation is planned in R9
    • latest updates:
      • Thinh has presented the alternative package solution in the CNF taskforce call, could be discussed in future calls
      • CNF requirements collaboration pending discussions as well, could be discussed in this week's CNF taskforce call
    • plan to have a conclusion next Monday, and then share to modeling team
      • current gap is that whether NFVO needs to understand the helm chart, and whether ASD can be totally non-overlap with helm chart
  • CNF runtime model
    • Proposal:
      • for Istanbul: add some necessary information as an enhancement of vf-module, to allow components to query k8s objects
      • for Jarkata: define a cnf-module, to store information like compute (pod), storage, etc.
      • the two sub-proposals can co-exist
    • Update:
      • 
      • the idea is to capture the basic information from k8s
      • the proposal has been presented to the A&AI team, and no major concerns
    • Questions:
      • if A&AI team can support modification of existing models (in case in later release, ETSI alignment team/ETSI standard identified changes needed for the runtime model), Lukasz will help check with A&AI PTL
      • align with ETSI alignment team
  • 5G service / CPS model
  • PNF instance model
    • reverse engineering
      
      • feedback to A&AI team:
        • some relationship lack description, and the existing description may not be meaningful enough
      • current status: AAI Schema Reverse-Engineering to Papyrus
  • Topology model
    • Proposal: https://wiki.onap.org/display/DW/Abstract+Topology+Model
      • Martin will update the models with the IM sketch
    • Model Sketch: https://wiki.onap.org/display/DW/Proposed+Topology+IM+Sketch
      
      • inspired by TAPI model to add "link", "connection" classes
      • looking at ORAN use cases and see if the models can fulfill the requirements
      • TAPI presentation may be found here: otcc2019.KS.002_TAPI_Concepts_Topology_Connectivity.pptx
    • Andy has helped to create a high level requirement for the topology model
      • expecting ORAN to provide relavent use cases
      • Martin and Andy are aware of the different views of topology model presented last week by Cagatay
      • mainly triggered by ORAN WG10, also related to WG1's slicing use case, etc.
      • how to model different layers, physical, logical topology, etc.? current methodology is using UML/papyrus to capture the models
    • Latest updates:
      • Martin is working on the TAPI model, and has discussed with the SON use case team to receive feedback from themAndy has updated the diagram to better align with the TAPI names
• Modeling Documentation
  
  • gendoc template discussion:
    • whether the description only applies for a navigatable end of an association
    • add relationship documentation to the UML guideline: 

      Jira
      server ONAP JIRA serverId 425b2b0a-557c-3c0c-b515-579789cceedb key ONAPMODEL-28

    • UML principle wiki page:
      • Principle and Guideline for Information Model Proposal Using Papyrus (Draft)
      • review the updates to the Gendoc requirements part
        • Michela suggest whether it's possible to add information of associations into the class definitions
          • Xu will investigate it offline
      • Using Papyrus for Modeling updates
