3. Service Maturity NCMP (TBC)
4. Performance (CPS, NCMP)
   1. CPS Data read 
   2. CPS Model-based query
   3. Registration algorithm change (using schemaSet hash)
5. CM Handle Connectivity State
6. Notification Configuration

CPS-NCMPCM Handle Connectivity Freshness/Staleness
11CPS-Core /
CPS-NCMPSupport for list as top level data node
12CPS-Core /
CPS-NCMPSupport for multiple top-elements from different modules in one CM handle/anchor13NCMP-CPSSupport NCMP-CPS upgrade

Currently only custom upgrade is supported. (upon request)

Requirement: It shall be possible to upgrade NCMP-CPS from release N-1 to N (without requiring manual intervention/workarounds). N is defined as any release requested by ESH

• Note. Need to agree version strategy: use current ONAP x.y.z. numbering. Ericsson to communicate when a version is to be 'delivered' and 'y' increased

Technical Debt to be addressed: Liquibase is used in CPS to manage data(upgrades) in CPS

Study: Resolve technical debt (mixed data). NCMP Data upgrade. CPS Core need to support model upgrade so that NCMP can use it,

14CPS-Core
NCMP-CPSSupport multiple identifiers (alternatives for CM Handle ID)

15
Support for 'Instance Identifier'Should be possible to identify a cmhandle using multiple instance identifiers
16CPS-NCMPInvoke YANG modelled action

Always on operational datastore.  Supported for nmcp:passthrough-operational and if executed against ncmp:operational then it is always forwarded to dmi plugin.  Is there another story for forwarding to be included as a dependency? Always run as async request.  Is this dependent on CPS-1127  - see spin-off user stories table below this on.

KMC : Can we deprioritize - this can be run against passthrough-operational for now.  Just have to agree on the API / URL for the action to progress at this stage so that the passthrough-operational form is aligned with final operational form.

17
CPS-NCMPEnhanced query support

Currently the passthrough has an 'fields' parameter to do a scoped query.  Propose to support this in non-passthrough so it is promoted to a fully supported option, e.g. {ncmp-root}/ncmp/v1/ch/335ff/data/ds/ncmp-datastore:passthrough-operational?

               EndpointResource/LocalSctpEndpoint/attributes(interfaceUsed==X2))

KMC : Do we support restconf like queries or xpath only?

18Move above 8CPS_Core / CPS-NCMPUpdate YANG schema-set for CM handle without removing and adding it

Cached data is not in scope. Need to specify orphan handling of YANG modules.

Needed for node upgrade scenario.

19CPS-NCMPRetrieve single module resource/v1/ch/{cm-handle}/modules/definitions/{moduleName}

20
CPS-Core / CPS-NCMPExisting CPS-path based queries across all CM handles for cached data

Look to define the interface specification for this only.

(but best way is to implement for operational/cached data to determine any output formatting issues)

21
CPS-Core /
CPS-NCMPAccess control for public interfaces (NCMP, CPS-Core, DMI?)KMC : What level of access control is there today - both on CPS and NCMP interfaces?

22
CPS-NCMPFine-grained cache configuration
