Yang: Open-Source Modeling Language

An open-source modeling language for designing data models and APIs, providing a simple way to model complex data structures using a tree-based hierarchy.

What is Yang?

Yang is an open-source modeling language developed by the IETF for defining data models and APIs for network configuration and operations. It is commonly used in networking devices and software to model data structures and interfaces in a standardized way.

Some key features of Yang include:

• Tree-based hierarchical data models for complex structures
• Reusability through import and include statements
• Extensibility through augmentations and deviations
• Validation through built-in types and constraints
• Code generation for APIs based on the defined models

Yang models abstract low-level details and allow focus on the overall structure and syntax of data. This makes configuration and integration much simpler. The models can be used to generate code for APIs that allow manipulating the data. There are libraries available to easily integrate Yang with programming languages.

As an open standard, Yang enables modeling device configurations across vendors and platforms. This interoperability helps with managing heterogeneity in networking infrastructure. The declarative nature also allows version control and tracking of changes. Overall, Yang is emerging as a key enabler for programmable networks and automation using standardized data models.
