John, For draft-kumar for consumer-facing interface information model, you can give the authors further constructive suggestions because you did good job in I2NSF capability information model. IMHO, the current draft-kumar is good for at least firewall and web-filter through the implementation experiences of my SKKU team at the last three IETF hackathons. So I believe that draft-kumar can be a good starting point for consumer-facing interface.
For the data models, as you mentioned, we authors followed the legacy YANG models. The object-oriented data model such as SUPA will be a good candidate. As the WG becomes to have a consensus to use which YANG model between the legacy YANG model and the object-oriented YANG model, we authors of the data models will be able to work smoothly according to the decision. Actually, my SKKU team have already been considering how to use the concept of the object-oriented features for YANG data models. For the NSF-facing interface data model, we can modify our data model such that the common variables used by Event, Condition, and Action clauses will be made into objects and be shared by them through aggregation. If you know other object-oriented YANG models other than the SUPA data model, please let us know them to refer to them. Thanks for your considerate analysis and contribution to our I2NSF WG.
