YANG Data Models

YANG is a data modeling language used to model configuration and state data as published in RFC 6020. The Representational State Transfer Configuration Protocol (RESTCONF) interface supports YANG models defined by standards bodies and community groups such as IETF and OpenConfig, as well as native YANG models. Some aspects of the data model to note:

Every data model is a module, a self-contained top-level hierarchy of nodes.
The data model uses containers to group related nodes.
The data model uses lists to identify nodes that are stored in sequence.
Each individual attribute of a node is represented by a leaf.
Every leaf must have an associated data type.

Callout	Description
1	Module name
2	Data type
3	Leaf
4	List
5	Container
