Merge-Patch keyValues treats Object attributes as Property-of-Property

[jason-fox]

Create an entity with an Object property like Address:

curl -L -X POST 'http://localhost:1026/ngsi-ld/v1/entities/' \
-H 'Content-Type: application/json' \
-H 'Link: <http://context/ngsi-context.jsonld>; rel="http://www.w3.org/ns/json-ld#context"; type="application/ld+json"' \
--data-raw '{
    "id": "urn:ngsi-ld:City:001",
    "type": "City",
    "address": {
        "type": "Property",
        "value": {
            "streetAddress": "Kanlıca İskele Meydanı",
            "addressRegion": "İstanbul",
            "addressLocality": "Beşiktaş", 
            "postalCode": "34800"
        }
    }
}'

Attempt to update with keyValues:

curl -L -X PATCH 'http://localhost:1026/ngsi-ld/v1/entities/urn:ngsi-ld:City:001?options=keyValues' \
-H 'Link: <http://context/ngsi-context.jsonld>; rel="http://www.w3.org/ns/json-ld#context"; type="application/ld+json"' \
-H 'Content-Type: application/json' \
--data-raw '{
    "address": {
        "addressLocality": "Fenerbahçe",
        "postalCode": "99999"
    }
}'

The subattributes are treated as Property-of-Property rather than part of the object. In normalized terms, this update should be considered as:

 "address": {
        "type": "Property",
        "value": {
             "addressLocality": "Fenerbahçe",
             "postalCode": "99999"
        }
}

Not as

 "address": {
        "type": "Property",
        "value": { ...}
        "addressLocality":  {
             "type": "Property",
             "value": "Fenerbahçe"
       },
        "postalCode":  {
             "type": "Property",
            "value": "99999"
        }
}
