Minutes:

• Agenda bashing
  • seems there's an overlap with O-RAN meeting every two weeks, will discuss next week how to address the issue
    • Jacqueline suggests we could have one meeting every two weeks, and avoid overlap with the O-RAN model meeting
    • Xu will bring it to the modeling subcommittee call / mailing list
• 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：
      • Fred presents the latest progress: a wiki page on IFA011 v4.2.1 changes, ETSI IFA011 v4.2.1 Changes to ONAP Resource Model.
      • intention: update from v4.1.1 to v4.2.1
        • adding of VipCpdProfile, VipCpLevel, LcmCoordinationActionMapping classes, and related changes
        • introducing vnfdExtInvariantId at the vnfd
        • add two attributes in VipCpd: intVirtualLinkDesc, dedicatedIpAddress
        • name change of volumeTemplate → perVnfcInstance (in virtualStorageDesc)
      • papyrus changes already submitted by Fred
  • ASD model
    • Proposal: Application Service Descriptor (ASD) onboarding IM
    • Plan for the PoC: Application Package Onboarding to SDC
  • 5G service / CPS model
  • Reverse engineering
    • Jacqueline presents the current work on reverse engineering based on the simplified k8s resource proposal
      • updates: the k8s-resource object has been re-positioned, and associations also updated
    • the diagram shows the model of vf-module, tenants, etc. and their relationship with K8sResource class
    • next step:
      • Jacqueline will work on the papyrus model to bring in the A&AI objects (generic-vnf, tenants, etc.)
  • 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
    • Latest updates:
      • comment: remove ManagedReference to simplify the model
      • 
• Modeling Documentation
  
  • gendoc template discussion:
    • whether the description only applies for a navigatable end of an association
    • add relationship documentation to the UML guideline:  ONAPMODEL-28 - Getting issue details... STATUS
    • 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
