#	Description	Notes	Decision
1	No Event properties defined for DMI AVC Event		Priyank Maheshwari will need to specify and agreed event structure for DNI AVC Event with stakeholders
2	No Event properties defined for Bulk Response Events [Internal & client]
3	Should all the events have same kafka headers		kieran mccarthy 26 Apr 2023 Posissbly Posissbly Common (base) set of headers but mandatory aspect might differ. In parctvie practice we might need a separate headers (shema?) for each event
4	Clarify the format of the version eventSchemaVersion	v1 or 1.0	kieran mccarthy to check ORAN preference
5	What to do with additional event headers (from DMI Plugins)		kieran mccarthy 26 Apr 2023 if DMI produce Additional headers NCMP will discard thoe ie. not included in forwarded events

#2 DMI

Data AVC Event (ONAP DMI → NCMP)

Description

DMI A normalized AVC Event (DMI → NCMP)that ONAP DMI Plugin will send to NCMP. NCMP can process the event and update cached data if needed. See 5 in CPS Data Notifications Overview#ComponentDiagram
Other DMI Plugin might snet similar events, using same headers but different payload and value for 'eventSchema' Depending on the AVC subscription details those events might or might not be forwarded to the Client Apps.
