Mandatory Attributes

[PrathibaJee]

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.

S.No	Grouping/Datatype	Attribute	Mandatory	Optional
1	object-creation-notification	object-id-ref
2	object-deletion-notification	object-id-ref
3	attribute-value-changed-notification	object-id-ref
4	current-performance	granularity-period
5	historical-performance	granularity-period
6		period-end-time
7	ethernet-container-configuration	scheduler-profile
8		ingress-policing-profile
9		qos-profile
10		header-compression-kind
11	header-compression-kind	header-compression-name
12	available-queue-type	queue-name
13	wred-behavior-type	affected-drop-precedence
14		affected-protocol
15		wred-profile
16	queue-behavior-type	queue-name
17	queue-utilization-type	queue-name

Making configuration attributes mandatory might force clients to provide these attributes in each configuration request.

Decision during the 5G-xhaul call on 6th of September 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)
5	historical-performance	granularity-period	X 1)
6		period-end-time	X 1)
7	ethernet-container-configuration	scheduler-profile		X
8		ingress-policing-profile		X
9		qos-profile		X
10		header-compression-kind	X 2)
11	header-compression-kind	header-compression-name	X 1)
12	available-queue-type	queue-name	X 1)
13	wred-behavior-type	affected-drop-precedence	X 1)
14		affected-protocol	X 1)
15		wred-profile	X
16	queue-behavior-type	queue-name	X 1)
17	queue-utilization-type	queue-name	X 1)

1) It is a key attribute 2) If header compression would not be supported by hardware an instance of HeaderCompressionKind has to be created with headerCompressionMode == NO_COMPRESSION
