- Onboarding: The Application Package is consumed by the orchestrator, that provisions all required artifacts in the repository.
- Orchestrator provisions the artifact repository.
- Helm client pulls the requested application’s chart from the repository.

O-RAN OAM Architecture Info Model with ASD
O-RAN delivery package with ASD
The proposal for packaging is to continue to rely on CSAR. The packaging of the containerized applications, the ASD itself, and the usage of ASD as a top-level artifact for a CSAR. The use of Helm as the cloud-native artifact for describing (pieces of) the application. It is recommended to adopt ETSI NFV SOL004, by adding the possibility to include an ASD instead of a VNFD as a top-level artifact.
