Re: [netconf] New draft: Augmentiton Addition into the IETF-YANG-Library

["Jan Lindblad (jlindbla)" <[e-mail]>]

Benoît, WG,

I listened to the presentation in the NETCONF WG, and now I have also read this draft. I think it's ok, even if it does not really provide clients with any new information that they can't access today. Since it is optional for servers to implement, I don't think there are any problems standardizing a module like this. Servers that often participate in use cases where clients find this shortcut to information useful may well choose to implement the augmentation.

If I may be very technical for a moment, I might add that the current definition of the augmentation leaf-list is a bit odd. It is a leafref referring to /yanglib:yang-library/yanglib:module-set/yanglib:module/yanglib:name. In this path there are two keys (module-set/name and module-set/module/name). That means you need two leafrefs to uniquely identify the module, one for each key leaf in the path. Instad of using a leaf-list of leafrefs here, I'd suggest modeling this as a traditional list with two leafref keys to avoid the problem. Other solutions are also possible. Perhaps naming this addition "augmented-by" would also make the contents clearer.

Best Regards,
/jan

Dear all,

Let me introduce this draft

Feedback on this brand new draft (done during the hackathon) is welcome;
