9 months ago Decision during the 5G xhaul call on 8th of November 2023:
UML2YANG tool will include mandatory substatements to attributes marked as mandatory.
| S.No | Grouping/Datatype | Attribute | Mandatory | Optional | |
|---|---|---|---|---|---|
| 1 | object-creation-notification | object-id-ref | X | ||
| 2 | object-deletion-notification | object-id-ref | X | ||
| 3 | attribute-value-changed-notification | object-id-ref | X | ||
| 4 | current-performance | granularity-period | X 1) | current-performance-data-list | |
| 5 | historical-performance | granularity-period | X 2) | historical-performance-data-list | |
| 6 | period-end-time | X 2) | historical-performance-data-list | ||
| 7 | wire-interface-configuration | fixed-pmd-kind | X | ||
| 8 | wire-interface-status | pmd-kind-cur | X | ||
| 9 | pmd-kind | pmd-name | X 3) | wire-interface-capability/supported-pmd-kind-list | |
| 10 | transceiver-configuration-type | transceiver-index | X 4) | wire-interface-configuration/transceiver-configuration-list | |
| 11 | receiver-status-type | receiver-index | X 5) | wire-interface-status/receiver-status-list |
- It is a key attribute of current-performance-data-list
- It is a key attribute of historical-performance-data-list
- It is a key attribute of wire-interface-capability/supported-pmd-kind-list
- It is a key attribute of wire-interface-configuration/transceiver-configuration-list
- It is a key attribute of wire-interface-status/receiver-status-list
For covering the two optional attributes the following changes shall be made:
- The comment of the WireInterfaceCapability::PmdKind::pmdName attribute shall be complemented by the following formulation: "An instance of PmdKind with pmdName='NOT_YET_DEFINED' shall always be provided.
- The existing formulation "If (autoNegotiationIsOn=1) value of this field becomes irrelevant" in the comment of the WireInterfaceConfiguration::_fixedPmdKind attribute shall be replaced by "If (autoNegotiationIsOn==1) or the current value of this attribute is not provided by the hardware, the instance of PmdKind with pmdName=='NOT_YET_DEFINED' shall be referenced".
- The comment of the WireInterfaceStatus::_pmdKindCur attribute shall be complemented by the formulation "If the current value of this attribute is not provided by the hardware, the instance of PmdKind with pmdName=='NOT_YET_DEFINED' shall be referenced".
The latest UML2YANG tool will include mandatory substatement to attributes that has "Multiplicity 1 + no default values defined". The following attributes which are formerly optional will be changed to mandatory in the upcoming YANG.
Further , if an attribute is decided to be optional , we shall handle it in the UML modelling by either introducing a default value or by modifying the Multiplicity to 0..1.
