new model

module name for the model that holds the augment statement

new module name = extended-dmi-registry

prefix = ext-dmi

Loading data with Liquibase

Dmi registry model is loaded via Liquibase which means that the content of the yang resource is already set

will the new model need to be loaded

how will the 'import' statement work to create a new model

ODL Yang tool

what is needed to acknowledge the augment statement for a new model

the new model will contain a prefix of the module name

the prefix is ignored by the yang parser currently used, this has been evident in
- - CPS-870: Align CPS-Core output with SDN-C output

Overview

Currently, the published DMI-registry model shows the property 'additional properties' as shown on lines 32 to line 43 of the yang model below. This property is not queryable and therefore, is not recommended to be published to the public.

See brief on YANG language on Support for Yang Language

By using the keyword 'augment' on yang models, we are allowed to extend a data model i.e. add nodes to the current structure

...

Using pyang tool, these two models were validated to confirm that the resulting schema tree module model includes the nodes that were intended to be added on to the dmi-registry model
