YANG Module Classification
Abstract
The YANG data modeling language is currently being considered for a
wide variety of applications throughout the networking industry at
large. Many standards development organizations (SDOs), open-source
software projects, vendors, and users are using YANG to develop and
publish YANG modules for a wide variety of applications. At the same
time, there is currently no well-known terminology to categorize
various types of YANG modules.
A consistent terminology would help with the categorization of YANG
modules, assist in the analysis of the YANG data modeling efforts in
the IETF and other organizations, and bring clarity to the YANG-
related discussions between the different groups.
This document describes a set of concepts and associated terms to
support consistent classification of YANG modules.

1. Introduction
The Internet Engineering Steering Group (IESG) has been actively
encouraging IETF working groups to use the YANG data modeling
language [RFC7950] and the Network Configuration Protocol (NETCONF)
[RFC6241] for configuration management purposes, especially in new
working group charters [IESG-Statement].
YANG is also gaining wide acceptance as the de facto standard data
modeling language in the broader industry. This extends beyond the
IETF to include many SDOs, industry consortia, ad hoc groups, open-
source projects, vendors, and end users.
