• Agenda bashing
• 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
    • Updates：
      • SOL001 is delayed and expected to be stable at the end of July
  • CNF runtime model
    • IM: Simplified K8S Resource Model - IM
    • questioncomments:
      • 1) need to create empty classes for "tenant", "vnf-module", etc.? A: will keep the comments as for now, and Jacqueline will help reverse-engineer the related classes
      2) whether the attribute definitions are acceptable? A: need further check, and needs double check with the model owner on "version", "group" descriptions.
      • the relationship between k8s-resource and cloud-region should be N:1 rather than 1:N
      • prefer to show the relationship in the diagram
      • suggest to add relationship with the root model
    • Xu will update the IM and discuss next week
  • 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
    • migrating to new version
      • Jacqueline has done the experiment of creating gendocs using two different versions of eclipse
        • the gendoc of the new version seems fine, but the gendoc of the old version breaks (missing parent class information)
      • AP:
        • Xu will try to experiment the same things as well, and discuss again next week
  • 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:
      • Tony provides some comments on the model sketch:
        • simplify the "service" models
        • relationship between the topology model and ONAP IM / root model
          • currently working on high level concepts, discussing whether we need to have certain objects in the ONAP IM, and maybe part of the topology model
          • e.g., Connectivity, EndPoint
        • from developer's perspective, suggest to avoid too many hops to access the models/info
        • intent part needs further discussion, and suggest to focus on aspects first
      • Andy will arrange further call to discuss the model
      Latest updates:
      • Adding concepts like clients and servers, further discussion are needed to for the context of the new terms
      • also whether the whole objects should be put under "ManagedFunction" needs further discussion
• Modeling Documentation
  
  • gendoc template discussion:
    • whether the description only applies for a navigatable end of an association
    • add relationship documentation to the UML guideline:

    • 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
