YANG is a data modeling language used to model configuration, operational state, asynchronous notifications, and remote procedure calls (RPCs) for network management. This document describes the syntax and semantics of version 2.0 of the YANG language (YANG 2.0). YANG 2.0 is a major release of the YANG language, updating version 1.1 of the YANG language in both backwards-compatible and backwards-incompatible ways.¶

YANG [RFC6020] [RFC7950] is a data modeling language used to model configuration, operational state, asynchronous notifications, and remote procedure calls (RPCs) for network management. In this sense, YANG is a domain-specific data modeling language having, e.g., first-class annotations for configuration and operational state, with rules for how they relate.¶
