#IssueNotesDecision
1List scenariosNeed to clarify scenariosRefer to Internal study
2Topicswhat topics are used in what scenario (topic for each Datastore ?)

See Topics section below.


All NCMP notifications to be published on the public cm-events topic by default regardless of data type, notification type or datastore the change came from.  This topics acts as the TBAC_ALL topic.

cm-events topic name should be configurable in deployment settings.


Future : In future NCMP shall publish the notification based on TBAC where the notification is published on the appropriate target group topic cm-events[-<target-group-name>] matching the target group(s) the data type(s) is associated with.  Not in scope of this story.

Data similar to the below needs to be reflected in the related cmhandle data model

{
     "cmhandleId" : <cmhandle-id>

     "subscriptions" :  {
          "operational" : {    # 'local' ncmp subscription is required with the cmhandle - store separately?
                 "administrativeState" : "active",
                 "datastore-xpath-filter" : <xpath-filter>
            },

          "running" : {   # 'local' ncmp subscription is required with the cmhandle - store subId separately?
                 "administrativeState" : "active",
                 "datastore-xpath-filter" : <xpath-filter>
            },

          "passthrough-operational" : {
                 "administrativeState" : "updating",   # if 'updating' then block/queue new sub's until 'active'
                 "subscriptionId" : "cc77765sddf",
                 "datastore-xpath-filter" : <xpath-filter>
            },

          "passthrough-running" : {
                 "administrativeState" : "active",
                 "subscriptionId" : <sub-id-of-device">,
                 "datastore-xpath-filter" : <xpath-filter>
            }

    }
}

The subscriptionId in the passthrough-* datastore subscription information represents the subscription created on the remote device.
