## What it is
A curated collection of YANG data models from standards organizations (IETF, IEEE, ETSI, MEF, Broadband Forum) and vendors, maintained in a single repository. It serves as a central reference and distribution point for network configuration and telemetry schemas.

## Use cases
- find standard YANG modules for network device configuration
- download IETF standards-track YANG models
- validate vendor YANG modules against CI checks
- browse IEEE and MEF YANG schemas for network automation
- locate YANG models for NETCONF or RESTCONF tooling
- contribute vendor-specific YANG modules to a shared registry

## When to choose
- you need authoritative, up-to-date YANG modules from standards bodies
- you are building network automation or configuration tools that consume YANG schemas
- you want a single place to track and contribute vendor and standard models

## When to avoid
- you need a YANG compiler, validator, or runtime tool rather than the model files themselves
- you need a license-clarified redistribution since the repo has no explicit license
- you need application software rather than schema datasets

## Facets
- artifact type: dataset
- maturity: active
- function: developer-tools, networking, configuration-management, documentation
- domain: networking, developer-tools, apis
- platform: cross-platform
- tags: yang, ietf, ieee, network-configuration, data-models, standards, netconf, schema, automation
