[NETCONF-845] Support of namespace for referred yang-identity values

Duplicate — Fri, 30 Jun 2023 12:41:24 +0000

Greetings from O-RAN-SC

Story:
We use OpenDaylight as O-RAN O1-Controller for RESTCONF to NETCONF translation and vice versa within ONAP/CCSDK.

For O-RAN Architecture and Specification validation a yang module for Performance Monitoring Job management was developed:

Please see https://gerrit.o-ran-sc.org/r/gitweb?p=scp/oam/modeling.git;a=blob;f=data-model/yang/working/o-ran-sc/o-ran-du/o-ran-sc-du-hello-world.yang;h=74351c8b6a58e817f90694fc874ead39f304ea74;hb=HEAD#l775 the list of measurement counters which should be reported.

Each counter is identified withing the yang module as yang-identity.

Finding:
When sending a PM-Job creation for a certain monitoring point (resource, object class) for the counter 'user-equipment-average-throughput-uplink' via RESTCONF ...

see [o-ran-sc-du-hello-world:performance-measurement-type='user-equipment-average-throughput-uplink']

... the converted namespace of the counter is not according to RFC7950.

Instead of ...

the expectation is ...
