Application Service Descriptor (ASD) Resource Data Model
- Marian Darula
- Zu Qiang
The Application Service Descriptor (ASD) Resource Data Mode is created based on the ONAP agreed Application Service Descriptor (ASD) onboarding Information Model, ver. 1.0.
The application service descriptor resource data model specified in this wiki page includes the ASD node type, ASD data type, ASD artifact type and ASD package format. This data model specifies the format of a vendor provided ASD package which is going to be onboarded to ONAP.
This application service descriptor (ASD) resource data model is specified in the scope of ONAP PoC implementation.
If the ASD concept is accepted by any standardization organization (e.g. ORAN), ONAP may open the discussion on how to align the ONAP implementation with the standard defined ASD data model.
