How it works...

OpenDaylight has a model-driven architecture, which means that all of its components are modeled using YANG. While installing features, OpenDaylight loads YANG models, making them available within the MD-SAL data store.

YANGUI is a representation of this data store. Each schema represents a subtree based on the name of the module and its revision-date. YANGUI aggregates and parses all those models. It also acts as a REST client; through its web interface we can execute functions such as GET, POST, PUT, and DELETE.
