The initial focus of OpenConfig has been the development of vendor-neutral data models for configuration and management that will be supported natively on networking hardware and software platforms. OpenConfig has adopted YANG 1.0 as the data modeling language for building configuration and operational state models.
These models may be developed directly by OpenConfig, or compiled from 3rd party modules that conform with the OpenConfig requirements. OpenConfig is interacting with standards bodies, and network equipment manufacturers - and intends that these models will become the basis of widely-adopted, standardized interfaces.
Our YANG modules are published periodically in our public github repository for review and usage by the broader community.
