      • comments from last time:

        • need to double check the class "VnfLcmOperationCoordination", if that's aligned with IFA

          • @Fernando Oliveira VnfLcmOperationCoordination is a new Information element that was introduced in IFA011 v3.3.1 https://www.etsi.org/deliver/etsi_gs/NFV-IFA/001_099/011/03.03.01_60/gs_nfv-ifa011v030301p.pdf section 7.1.6 page 73.  SOL001 v3.3.1 does not yet support this datatype and functionality.

          • will add a note to highlight the info

        • modify the note, change "Vnfd" to "Vdu"

    • related DM model: VNF/CNF Data Model Based on ETSI v3.3.1 SOL001 plus CNF Enhancements

      • has submitted a contribution to SOL001, hope to reach agreement in March

      • question:

        • swImageArtifact is overlapping with helm charts, why have 2 paths? A: main rationale is to avoid parsing the helm charts

        • what if there are misalignments between helm charts and other files? A: plan to develop a VNF validation tool in future release

        • what's the benefits for having VNFD on top of helm charts? A from Thinh: VNFD contains more connectivity info than helm charts, but would suggest to avoid duplication where possible, e.g., container level compute/network resources could be described within helm charts

      • whether SO would parse helm charts is open to the community

      • will discuss with direct path team about the common package issue

  • 5G service

  • PNF instance model

  • Topology model

    • Martin gives a brief presentation on abstract topology model: https://lf-onap.atlassian.net/wiki/display/DW/Abstract+Topology+Model

    • triggered by discussion between ONAP and O-RAN

    • could be extended to other use cases

• Modeling Documentation
  
  

  • R6 readthedocs review:

    • gendoc template improvement: ONAP Information Model - Gendoc Examples 

    • discussion whether the description only applies for a navigatable end of an association

      • continue discussion later

  • add relationship documentation to the UML guideline: ONAPMODEL-28: Using the Documentation Property for RelationshipsOpen

    • 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

        • suggest to further discuss the version recommended after Jacqueline come back
