Data Input / Output

...

Consistency

In order to make custom root pointer solution (described above) work properly, it should point to parent of data node being updated.
At the same time the JSON data require to be presented as a single entry explicitly defining a type of a current node.

From other hand when same data node is requested for output (GET) it addressed by direct xpath and value returned is a data
unwrapped (as is: multiple top level elements).

Below is example using a data fragment referencing ran-network2020-08-06.yang model Getting data node

// xPath: /ran-network/NearRTRIC[@idNearRTRIC='11']/GNBDUFunction[@idGNBDUFunction='1']/NRCellDU[@idNRCellDU='103594001']/attributes/pLMNInfoList[@mcc='310' and @mnc='410']
// JSON:
{ 
   "mcc": "310",
   "mnc": "410",
   "sNSSAIList": [{
       "sNssai": "10000100",
       "status": "INACTIVE",
       "configData": [{
           "configParameter": "maxNumberOfConns",
           "configValue": 5000
        }]
    ]}
}
