   title DME to NCMP Subscription Request linenumbers true collapse true
   Header values ( all cloud events header ) { "data": { "subscriptionId": "unique subscription id", "predicates": [ { “targets” : list of cmhandles "datastore": “ncmp-datastore:passthrough-operational or ncmp-datastore:passthrough-running", "datastore-xpath-filter": list of valid xpaths } ] }

   
   
   

2. NCMP to DMI-Plugin Subscription Request
   
   

   Code Block
   title NCMP to DMI-Plugin Subscription Request linenumbers true collapse true
   // correlationId for tracking { "data": { "cmhandles" : [ { "cmHandleId": "cmhandle1", "private-properties": {...} }, { "cmHandleId": "cmhandle2", "private-properties": {...} }, { "cmHandleId": "cmhandle3", "private-properties": {...} } ] "predicates": [ { “targets” : [“cmHandle1”, “cmHandle2”, "cmhandle3"] "datastore": “ncmp-datastore:passthrough-operational", "datastore-xpath-filter": ["p1/c1", "p2/c2"] }, { “targets” : [“cmHandle1”] "datastore": “ncmp-datastore:passthrough-running", "datastore-xpath-filter": ["p3/c3", "p4/c4"] } ] }

   
   
   

3. DMI-Plugin to NCMP Subscription Response
   
   

   Code Block
   title DMI-Plugin to NCMP Subscription Response linenumbers true collapse true
   Headers will have relevant fields including the subscriptionId // correlationId for tracking - to link with NCMP. ( get clarity ) { "data" : { "dmiName":"<dmiName>", "statusCode": "1", // open issue for the status codes ( whether to use the same for DMI to NCMP as for NCMP to Clients) "statusMessage" : "accepted/rejected" } }

   
   
   

4. NCMP to DME Subscription Response
   
   

   Code Block
   title NCMP to DME Subscription Response linenumbers true collapse true
   Headers will have relevant fields including the subscriptionId { "data": { "subscriptionId": "sample-subscription-id", "accepted-targets" : ["ch-1", ...], "rejected-targets" : ["ch-1", ...], "pending-targets" : ["ch-1", ...], } }
