• https://wiki.onap.org/display/DW/AAI+EdgeRules+UML
• Reverse-engineering AAI data model to Papyrus information model

Minutes:

• agenda bashing
  • start to work under "R6 workspace"
  • update of PNF non-MANO artifact proposal
    • still under discussion
• AAI reverse engineering discussion
  • Keong's presentation on PlantUML tool
    • source file is the swagger API document
    • result contains two parts: classes and edge rules (relationships)
    • AAI is working on integrating the tool into the model browser
    • suggestion:
      • may use the tool to show other project's models
      • may help generate xml to put into papyrus
    • pro: automatic way to generate diagram, independent on schema changes, easy to navigate the whole model
  • Jacqueline's presentation on Papyrus tool
    • source file is XSD, edge rule file (json) and possibly traversal information (json)
    • only shows classes now, no edge rules
    • pro: could be directly put into papyrus, automatically show all attributes (though no descriptions now)
    • question:
      • attribute multiplicity/cardinality seems losing some information (e.g., pnfName should be required attribute, but the corrent result shows 0..1 for multiplicity)
    • currently working on swagger → UML (a tool named wapiml)
  • how to proceed:
    • Xu:
      • 2 approaches in mind:
        • top down: start from investigating hierachy tree and work on details lately
        • bottom up: start from individual targets/topics e.g., PNF, VNF instances and build the tree
      • side questions:
        • whether modeling subcommittee or AAI team should handle updates of the instance model (after the model alignment)
    • suggestion:
      • categorize by use cases, try to cover all models used by use cases
        • CCVPN use case: AAI-CCVPN Schema Proposal for Casablanca Release
      • how aai model is related to IM discussion, need to do some comparison and analysis
  • AP: start with PNF instance model next week, analyze the attributes, class hierarchies, etc.; Xu will investigate on the hierarchy tree (from CCVPN) for further discussion
