Minutes:

  • 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
      • 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:
      • AP:
        • will continue how to document the information model: Simplified K8S Resource Model - IM
        • question:
          • 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.
    • 5G service / CPS model
    • PNF instance model
      • reverse engineering
      • 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
      • 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:
        • 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
