• Agenda bashing
  • reminder for filling R9 high level requirements: https://wikilf-onap.onapatlassian.orgnet/wiki/display/DW/ONAP+R9+Modeling+High+Level+Requirements
    
    • new requirements may be added after more use case presentations
    • plan to review intent based networking model proposals next week
  • time change for modeling subcommittee call
    • Andy has discussed with Ben, and plan to not change the time for now, will have further discussion on modeling subcommittee call
• 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://wikilf-onap.onapatlassian.orgnet/wiki/pages/viewpage.action?pageId=9301177216463007
      • 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
  • 5G service / CPS model
  • PNF instance model
    • reverse engineering
      • AAI model is visible in papyrus now through reverse engineering
      • have to do the diagram by hand though
        • would like to simplify the view/links of PNF, but would prefer not to remove the content → may need sought of aggregation in the models
      • Jacqueline will try to create a gendoc document and share it next weekgendoc has been created and is presented by Jacqueline
        • the document is useful because of easier understanding
        • for example, the description shows there are several attributes/models marked not working for now ("not correctly populated", etc.)
      • question is which content to focus for now (considering the document has 500+ pages)
        • Jacqueline prefer to start with PNF model (as originally proposed)
        • Andy agrees to start with PNF, and can further look at topology related items
        • Xu suggests to start with PNF, and then look at current model proposal related topics
      • may need to have a seperate directory to host the AAI models, to avoid potential non-compatible issue of papyrus
      • Andy suggests to mark all the models in experimental stereotype for now
      • Jacqueline will help upload the gendoc document
  • Topology model
    • Proposal: https://wikilf-onap.onapatlassian.orgnet/wiki/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 them
• 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 Legacy
      server System Jira serverId 4733707d-2057-3a0f-ae5e-4fd8aff50176 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
