This might have been discussed in the past, this Jira is just a placeholder to start a quick investigation and decide what we agreed to do or want to do now...

It has been noted that the json content for read and write requests in CPS-Core is inconsistent

Solution

For the JSON output of Get DataNode we need to alter the DataMapUtils class. The function toDataMap translates a datanode object to a JSON output. We only want this to occur on the parent node and as such we can create a new method which is called before toDataMap:

public static Map<String, Object> toDataMapParentNode(final DataNode dataNode) {
    final String nodeName = dataNode.getXpath().substring(dataNode.getXpath().lastIndexOf('/') + 1)
        .replaceAll("\\[.*?\\]", "");
    return ImmutableMap.<String, Object>builder().put(nodeName,
        toDataMap(dataNode)
    ).build();
}

We only want the container name on the highest parent level of the JSON output and as such have to distinguish between a parent level node and non parent level node. We create an outer map to wrap the inner map which creates the appropriate levels in the JSON output. 

This produces the following response in the Post Request output:

Tests would need to be updated to accept the new JSON output which is returned. Examples would need to be updated in openapi
