• CLAMP, DMaaP, ExtAPI, Holmes, MSB, MultiVIM, OOM, Policy, Portal, SDC, SO, SDNC, VFC, VNFSDK, UUI

producer-consumer pairings

Apart from "internal" AAI data, the data in AAI is produced by a non-AAI component and then consumed by another non-AAI component. Therefore the schema definitions and intended meanings of each schema element are not controlled by AAI itself.

See examples in AAI Schema Producer-Consumer Pairings

deployment tools

Tools (e.g. Helm, ansible, Docker Compose, etc) used to:

• place the microservices into their run-time environment

• distribute data files for initial configuration

• perform the initial configuration of microservices

• get the ONAP system running as intended

IDL Files

Some form of "Interface Definition Language" which unifies and replaces the OXM files and EdgeRule files as definition of AAI schema

Highlight change from predecessor ONAP Release

Amsterdam, Beijing

AAI Schema is:

• single-data-file configuration per version, i.e. one OXM file and one EdgeRule file

• distributed via source-code repository to AAI-internal-clients and ONAP-project-clients

• effective only upon microservice startup

Dublin and beyond

Each of the AAI-internal-clients and ONAP-project-clients will need to identify the relevant pieces of AAI schema that relates uniquely to their operations. The multiple-data-file configuration to be grouped by producer-consumer pairings.

Dublin and beyond

Each of the AAI-internal-clients will need to decide when/how to proceed with changing over to the updated methods of distributing the AAI schema.
