Summary

The NETMOD working group meeting at IETF 123 in Madrid covered document updates, versioning requirements, YANG packages, YANG configuration templates, validating context under anydata, and a proposal for handling deprecations and obsolescence in YANG models. The meeting included presentations, discussions, and polls to gauge working group interest in specific problem areas.

Key Discussion Points

Document Updates: Several documents have advanced in the RFC process, including the YANG syslog model, and updates related to versioning.
Versioning Requirements: Discussion on maintaining a current document outlining the requirements for YANG versioning.
YANG Packages: Review of YANG packages structure, hierarchy, and tooling, with a focus on simplifying and clarifying the draft document. Specific points included module tags, schema mounts, automatic resolution of module versions, excluding modules, and the definition of implementing a package.
YANG Configuration Templates: Introduction of a new internet draft proposing a templating solution for data stores with similar configuration subtrees, including the application of templates and precedence rules.
Validating Context Under Anydata: Discussion on how to validate data under anydata using the YANG library, particularly in the context of YANG push.
Handling Deprecations: A proposal for addressing the issue of unreadable machine code when deprecations are handled.

Decisions and Action Items

Interface V-Lan Model & Interface Extensions: Scott and Rob will update the drafts after this IETF meeting.
Versioning Requirements: Keep the versioning requirements draft active.
YANG Packages: Continue progressing with the package work and document updates; progress on the package compiler.
YANG Configuration Templates: Review the design on configuration templates and their application with edit config; to review the metadata mechanism. Mail the list on key points.
Validating Anydata: Define the problem to be solved more clearly, solution to follow.
Handling Deprecations: Investigate solutions and report findings back to the working group.

Next Steps

Authors to address comments and suggestions from the working group on their respective drafts.
Discussions on the mailing list to clarify key concepts and address open issues.
Further development and testing of YANG package tooling.
Potential for additional interim meetings to progress work.
The next step for validation anydata would be to have an individual draft that specifically identifies the problem.
