     In particular we choose the format described below.
     Given the following example statements (expressed in N-Quads format):

+-------------------------------------------------------------------------------
   _:bn1          <http://pred/1> <http://value/1>         <http://graph/1> .
   <http://sub/2> <http://pred/2> "language literal"@en    <http://graph/2> .
   <http://sub/3> <http://pred/3> "123"^^<http://datatype> <http://graph/3> .
+-------------------------------------------------------------------------------

     these will be represented as:

+-------------------------------------------------------------------------------
 {
    "quads" : [
        [
            {
                "type" : "bnode",
                "value" : "bn1"
            },
            "http://pred/1",
            {
                "type" : "uri",
                "value" : "http://value/1"
            },
            "http://graph/1"
        ],
        [
            {
                "type" : "uri",
                "value" : "http://sub/2"
            },
            "http://pred/2",
            {
                "type" : "literal",
                "value" : "language literal",
                "lang" : "en",
                "datatype" : null
            },
            "http://graph/2"
        ],
        [
            {
                "type" : "uri",
                "value" : "http://sub/3"
            },
            "http://pred/3",
            {
                "type" : "literal",
                "value" : "123",
                "lang" : null,
                "datatype" : "http://datatype"
            },
            "http://graph/3"
        ]
    ]
 }

    The <<JSON object>> structure is described by the following <<BNF>> rules,
    where quotes are omitted to improve readability:

+-----------------------------------------------------------------------------------------------------------------
 <json-response> ::= { "quads" : <statements> }
 <statements>    ::= [ <statement>+ ]
 <statement>     ::= [ <subject> , <predicate> , <object> , <graph> ]
 <subject>       ::= { "type" : <subject-type> , "value" : <value> }
 <predicate>     ::= <uri>
 <object>        ::= { "type" : <object-type> , "value" : <value> , "lang" : <lang> , "datatype" : <datatype> }
 <graph>         ::= <uri> | null
 <subject-type>  ::= "uri" | "bnode"
 <object-type>   ::= "uri" | "bnode"| "literal"
 <value>         ::= String
 <lang>          ::= String | null
 <datatype>      ::= <uri>  | null
 <uri>           ::= String
