[core] core-yang-library with the augmentation list

[Zhuoyao Lin <[e-mail]>]

Dear authors and CORE WG,

I am co-author of draft-yang-library-augmentdeby, in which we have introduce the augmentation dependency(the list name is augmentedby) as an element provided by YANG library.
Here is the link to draft

  *   https://datatracker.ietf.org/doc/draft-ietf-netconf-yang-library-augmentedby/01/

I read about the draft-ietf-core-yang-library describing the constrained version of YANG library, which mainly differs from the ietf-yang-library in terms of the reference and their type definition.

In draft-yang-library-augmentdeby, we are stressing the use case of YANG application(more specifically, YANG-Push) and Data Catalog where having accessible entire YANG reverse dependency provided in YANG library will be of great help.

  *   In the YANG application use case, having the augmentation and deviation can help application only getting the concerned module without having missing dependency (YANG-Push big picture: https://datatracker.ietf.org/doc/draft-ietf-nmop-yang-message-broker-integration/)
  *   In the Data Catalog use case, the full reverse dependency help build Data catalog metadata(YANG schema) for managing YANG data source
Here are references to the augmentedby integration:

  *   https://github.com/network-analytics/libyangpush/tree/feature/draft_augmentedby/docker_ietf120

We would like to know if applying the augmentation for core-yang-library and its use case will be of interest to the CORE WG?

We will be onsite in Dublin in IETF121. We are happy to have live discussion regarding this.
