Hi,

Please find the below structure of my JSON,

{  
"book": "testing\_mine",  
"res\_info": {  
"en": {  
"author": "guru"  
},  
"jp": {  
"author": "達人"  
},  
"tamil": {  
"author": "குரு"  
}  
}  
}

I need to create a mapping for the above JSON, the author filed is common but the language(en, jp, Tamil etc.,) object is changing. So please help how to create a mapping.
