What is YANG?
YANG is a data modeling language used to define the structure, syntax, and semantics of the data that network devices exchange through management protocols like NETCONF and RESTCONF. It describes exactly what configuration and operational data a device supports in a way that both humans and machines can understand. YANG models are the foundation of modern network automation: before a script or tool can configure a device via NETCONF or RESTCONF, it needs to know the YANG model for that device to understand how to structure its requests correctly.
