[jira] [Created] (OLINGO-1485) OData V4: Server side support for instance annotations

Ramya Vasanth created OLINGO-1485:
-------------------------------------

             Summary: OData V4: Server side support for instance annotations
                 Key: OLINGO-1485
                 URL: https://issues.apache.org/jira/browse/OLINGO-1485
             Project: Olingo
          Issue Type: New Feature
          Components: odata4-server
    Affects Versions: (Java) V4 4.7.1
            Reporter: Ramya Vasanth


If the Entity includes instance annotations or the Properties of the entity includes instance annotations, then olingo library serializer currently cannot serialize this.

The serializer should return a response like below..
This has instance annotation on the entity and property
{noformat}
{
	"@odata.context": "$metadata#ESAllPrim/$entity",
	"@odata.metadataEtag": "W/\"metadataETag\"",
	"@com.contoso.display.highlight":true,"
        "@com.contoso.PersonalInfo.PhoneNumbers": ["(203)555-1718","(203)555-1719"]
	"PropertyInt16": 32767,
	"PropertyString@com.contoso.display.style": {
		"@odata.type": "#com.contoso.display.styleType",
		"title": true,
		"Order": 1
	},
	"PropertyString": "First Resource - positive values",
	"PropertyBoolean": true,
	"PropertyByte": 255,
	"PropertySByte": 127,
	"PropertyInt32": 2147483647
}
{noformat}
The above payload should also be deserailized by olingo deserializer.
