• https://lf-onap.atlassian.net/wiki/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
