Technical Summary
This document provides for the association of tags with YANG modules. The expectation is for such tags to be used to help classify and organize modules. A method for defining, reading and writing modules’ tags is provided. Tags may be standardized and assigned during module definition, assigned by implementations, or dynamically defined and set by users. This document provides guidance to future model writers and, as such, this document updates RFC 8407.
Working Group Summary
The WG had significant questions on how module tags might be used. Section 1.1 of the document dwells on how and why module tags are applied, addressing significant points in this discussion from the vantage point of WG participants. Possible usage of the module tags was the most controversial part of the document progress, which eventually came to consensus.
Document Quality
There is a substantial interest from the model user community to have module tags functionality available. The document has received significant reviews, including vigorous WG debate that resulted in significant changes to the document and multiple WG last calls. YANG doctors have reviewed the document.
Personnel
Joel Jaeggli is the Document Shepherd for this document. Alissa Cooper is the Responsible Area Director.
IANA Note
