Introduction

The Model-Driven Service Adaptation Layer (MD-SAL) is message-bus inspired extensible middleware component that provides messaging and data storage functionality based on data and interface models defined by application developers (i.e. user-defined models).

The MD-SAL:

Defines a common-layer, concepts, data model building blocks and messaging patterns and provides infrastructure / framework for applications and inter-application communication.

Provide common support for user-defined transport and payload formats, including payload serialization and adaptation (e.g. binary, XML or JSON).

The MD-SAL uses YANG as the modeling language for both interface and data definitions, and provides a messaging and data-centric runtime for such services based on YANG modeling.

The MD-SAL provides two different API types (flavours):

MD-SAL Binding: MD-SAL APIs which extensively uses APIs and classes generated from YANG models, which provides compile-time safety.
MD-SAL DOM: (Document Object Model) APIs which uses DOM-like representation of data, which makes them more powerful, but provides less compile-time safety.
