About YDK¶

Overview¶

The YANG Development Kit (YDK) is a software development tool, which provides API for building applications based on YANG models. The main goal of YDK is to reduce the learning curve of YANG data models by expressing the model semantics in an API and abstracting protocol/encoding details. YDK is composed of a core package that defines services and providers, plus one or more module bundles that are based on YANG models.

Backwards Compatibility Notes¶

Although YDK-0.9.0 API did not change much, it generates slightly different code and model API comparing to YDK-0.8.5. However the Python model API generated by YDK releases starting from 0.7.3 is fully compatible with YDK-0.9.0. Hence all model bundles located in Python Package Index could be installed and used in YDK-0.9.0.

NOTE. Starting from release 0.8.5 the YDK does not support Python2 interpreter as it was deprecated.

Version¶

Current YDK version: 0.9.0
