Agenda

The purpose of the meeting was to have each group the has done some sort of ONAP Model Driven/Enabled in the past year to explain their view.

**Meeting was not recorded**

 General DiscussionAll  
  • None of the 3 presentations contradicted any others presentations
  • Everyone was in agreement that we should have a common internal model because;
    • Custom code causes delays and increase cost
    • ONAP components should only process one internal model  
  • Need to preserve on boarding artifacts
  • We should probably look at the SDC Internal model to see what is actually in it
  • Need to take an inventory of what components are using TOSCA model concepts
  • Need to define Gaps
  • 3 other work efforts are taking place related to Model Driven ( CDS , API Documentation Project, SO POS (Driven by TOSCA syntax) )
  • CDS is a project that has implemented some TOSCA syntax processing  
    • Yuriy talked about CDS
    • He presented CDS at Antwerp
    • Link to what Yuriy presented in Antwerp is listed above.
    • Policy is using same concepts
    • Not all people were aware of CDS- will look into learning more about it  
  • API Documentation Project
  • SO POC – processing driven by TOSCA syntax


  • Next Steps
    • Continue meeting every two weeks on Monday
    • Look at the current internal model
    • Define what is are target goal and how to get there without breaking things that work.
    • Define any Gaps.
    • Who else should be part of these discussions?

First review by Samuli from Samsung.

  • Reviewed a couple slide from his CNF presentation (link to deck is posted above)
  • Focused was onboarding process
  • ONAP has made multiple attempts to generalize modeling and orchestration
    • TOSCA
    • ETSI
    • Blueprints , etc…
  • Need to choose a single common modeling language  - TOSCA
  • TOSCA is expressive and extensible
  • Any technology should be converted to an internal TOSCA format
  • Some translators already exist in ONAP

Second Review  by Ciaran
  • Ciaran summarized some slides from his full presentation ( link to full presentation above)
  • A high level view of modeling
  • Focused more on the interoperability between components  / api’s
  • Types of models – capability, extension and user
  • Need better API documentation , version control
  • Moving forward need a catalog  of models
  • Should probably include process models

Third Review …  Andy Mayer

 
  • Andy used the first couple of slide from his deck ..(attached)
  • Discussed model driven versus model enabled
  • Showed the model flow…. Create , Deploy and use Model
  • Described the onboarding flow:
    • Different types (yang, Heat, etc. ) are used as input to Service Designer (SDC)   
    • Each file is used as a building block to be converted by SDC to TOSCA Model (Internal)
    • Preserves some artifacts because not all info can be represented in TOSCA
  • Similar process as described by Simuli’s review
