CPS-2425 Event Schemas in ONAP

Schema prefix

All schemas should have urn:cps column be a prefix @Csaba Kocsis @Kolawole Adebisi-Adeolokun

We will just change the data schema field in the event header when we publish the event and we would still maintain the internal java type as is. Although we discussed during the meeting that it has no affect at your end but just to record the decision I am putting it here.

@Csaba Kocsis or @kieran mccarthy to provide more insights.

No issue

When we start populating a different data schema , will that seamlessly integrate with the code at your end ? Or we still have to coordinate this change ?

@Csaba Kocsis or @kieran mccarthy to provide more insights.

SDK Impacts at Ericsson. @Csaba Kocsis
NCMP Documentation to say listen on both the event schemas ( as the schema doesn't change ) @Priyank Maheshwari

Coordination Needed Nov 13, 2024

Talked about the non backward compatible changes from an end to end lifecycle of the event.

Agreed with @Csaba Kocsis and recorded the decisions in the below table ( Compatibility column ) Feb 20, 2025

Async Event DataOperation Event

NCMP Produces DataOperationEvent

Nov 13, 2024
urn:cps:org.onap.cps.ncmp.events.batch-response:1.0.0
NCMP to document changes related to old and new schema as content of the schema doesn't change.

No , Wont do
( used in the error cases )

Cm Notification Subscriptions

NCMP Produces and Consumes the events

Nov 13, 2024
urn:cps:org.onap.ncmp.events.subscription:1.0.0

Not used. Hence safe to change.

Dmi Data Avc Event

Events NCMP receives from DMI

Nov 13, 2024
urn:cps:org.onap.cps.ncmp.events.moi-changes:1.0.0
Note: MOI is Managed Object Instance or MO Instance.

No. This is coming from devices.

Note for subscription with different topics we can change it. ( new epic )

LCM ( Lifecycle Management Events)

NCMP Produces LCM Events

Nov 13, 2024
urn:cps:org.onap.cps.ncmp.events:cm-handle-lcm:1.0.0
Note : to be done only when this is compliant with Cloud Events.

NCMP Data Avc Event (northbound)

NCMP Produces AvcEvent

Nov 13, 2024
urn:cps:org.onap.cps.ncmp.events.cm-handle-changes:1.0.0
To be confirmed. Awaiting response from @kieran mccarthy or @Csaba Kocsis

Note : Agreed to leave as it is in alignment with 3GPP. ( based on comment from @kieran mccarthy )

Feb 11, 2025 CPS team proposed to use urn:cps:org.onap.cps.ncmp.events:inventory-event:1.0.0

Not yet used.

Safe to change.

TrustLevel Events

NCMP Consumes Device Heartbeat

Nov 13, 2024
urn:cps:org.onap.cps.ncmp.dmi.events:cm-handle-trust-level:1.0.0

Safe to change at NCMP side.

AP @Csaba Kocsis to do changes at the DMI plugin side in the future.

AsyncEvent - DataOperationEvent

^urn:cps:

^{org.onap.cps.ncmp.events.async1_0_0.DataOperationEvent:1.0.0}

^{org.onap.cps.ncmp.events.async1_0_0.DataOperationEvent}

^{urn:cps:org.onap.cps.ncmp.events.batch-response:1.0.0} Nov 13, 2024 ( Need to document in the RTD - same event , just the event schema name has changed )

Cm Notification Subscription ( Produce and Consume)

org.onap.ncmp.cm.subscription:1.0.0 ( Incoming to NCMP )

^{org.onap.ncmp.cm.subscription:1.0.0 ( Outgoing from NCMP )}

^{org.onap.ncmp.dmi.cm.subscription:1.0.0 ( Incoming to DMI Plugin from NCMP )}

org.onap.ncmp.dmi.cm.subscription:1.0.0 ( Outgoing from DMI towards NCMP )

^{org.onap.cps.ncmp.impl.cmnotificationsubscription_1_0_0.client_to_ncmp.NcmpInEvent}

^{org.onap.cps.ncmp.impl.cmnotificationsubscription_1_0_0.ncmp_to_client.NcmpOutEvent}

^{org.onap.cps.ncmp.impl.cmnotificationsubscription_1_0_0.ncmp_to_dmi.DmiInEvent}

^{org.onap.cps.ncmp.impl.cmnotificationsubscription_1_0_0.dmi_to_ncmp.DmiOutEvent}

ur:cps:org.onap.ncmp.events.subscription:1.0.0 Nov 13, 2024

urn:cps:^{org.onap.ncmp.cm.subscription:1.0.0}

DMI Data Avc (Consuming)
( CM Data Notifications coming to NCMP from DMI )

Since we are just consuming , hence the team publishing will decide the schema.

urn:cps:org.onap.cps.ncmp.events.moi-changes:1.0.0 Nov 13, 2024

Lcm ( Lifecycle Management Events )

^{Non Cloud Event
DataSchema : org.onap.ncmp:cmhandle-lcm-event
Version : 1.0}

^{org.onap.cps.ncmp.events.lcm.v1.LcmEventHeader}

^{Non Cloud Event
DataSchema : org.onap.ncmp:cmhandle-lcm-event
Version : 1.0}

urn:cps:org.onap.cps.ncmp.events:cm-handle-lcm:1.0.0 Nov 13, 2024 No change to be done now. Just name agreed.

NCMP Data Avc ( Used for publishing trustlevel changes)
Northbound

^{urn:cps:org.onap.cps.ncmp.events.avc.ncmp_to_client.AvcEvent:1.0.0}

org.onap.cps.ncmp.events.avc.ncmp_to_client.AvcEvent

??
urn:cps:org.onap.cps.ncmp.events.cm-handle-changes:1.0.0 ( do we use ncmp notify events ?? @kieran mccarthy )
