ONAP release 1 is to integrate ECOMP with OPENO seed code, but the modeling specification for release 1 is mostly inherited from ECOMP.
below figure shows most modeling spec for release 1.
from this figure, below modeling spec are needed between modules:
1) Import to VNFSDK : VNF CSAR
2) VNFSDK import to SDC: VNF CSAR
3) from SDC to SO : Service CSAR(Service descriptor)
4) from SDC to VFC: NS CSAR, VNF CSAR
5) from SDC to UUI: Service CSAR, NS CSAR
6) from SO to SDN-C: WAN
7) from UUI to SO: Config / WAN
In this case, following modeling specification will be published as below:
1) Service CSAR
2) NS CSAR
3) VNF CSAR
4) Service Descriptor
6) WAN
