AAI needs to dynamically operationalize new and updated models at run-time, with minimal downtime and coding, so that the latest service and resource models can be delivered quickly. To do this, AAI must update its internal model, external API and behavior to respond to change to service and resource models, including schema changes. There are changes required to align on implementation across different ONAP components to provide a more strategic model-driven A&AI implementation. For this release decomposing AAI model/schema artifacts (OXM/XSD) into a more granular approach will better enable extensibility and support logical subdivision of models.
