AAI
IMPACTS
1) Include category/role in the model schema
This will enable us to query the models by their category (NST/NSST/CST) from AAI by OOF during NST selection.
(Frankfurt improvements - Reference to NST selection flow)
Impacted Modules in AAI
aai-schema-schema - add role as part of the model schema
aai-babel - Babel converts the TOSCA artifact to AAI's XML format(Babel artifact). So, fetch category from TOSCA artifact and add it to Babel artifact.
