+
+    <p>An RDF Graph consists of a set of RDF triples, each triple consisting
+    of a subject, a predicate and an object (formally defined in [<cite><a class="bibref" rel="biblioentry" href="#bib-RDF11-CONCEPTS">RDF11-CONCEPTS</a></cite>]).
+    An RDF/JSON document serializes such a set of RDF triples as a series of nested 
+    data structures. </p>
+
+    <p>A conforming RDF/JSON document consists of a single JSON object called
+    the root object. Each unique subject in the set of triples is represented as a key
+    in the root object. No key may appear more than once in the root object.</p>
+    
+    <p>The value of each root object key is a further JSON object whose 
+    keys are the URIs of the predicates occuring in triples with the
+    given subject. These keys are known as predicate keys. 
+    No predicate key may appear more than once within a single object.</p>
+    
+    <p>The value of each predicate key is an array of JSON objects representing 
+    the object of each serialized triple.</p>
+    
+    
+
+    <p>In general, a triple (subject S, predicate P, object O) is 
+    serialized in the following structure:</p>
+
+    <pre>{ &quot;S&quot; : { &quot;P&quot; : [ O ] } }</pre>
+
+    <p>The object of the triple O is represented as a further JSON 
+    object with the following keys:</p>
+
+    <dl>
+      <dt>type</dt>
+      <dd>one of 'uri', 'literal' or 'bnode' (required)</dd>
+      <dt>value</dt>
+      <dd>the URI of the object, its lexical value or a blank node label depending on whether the object is a uri, literal or bnode
+      </dd>
+      <dt>lang</dt>
+      <dd>the language of a literal value (optional but if supplied it must not be empty)</dd>
+      <dt>datatype</dt>
+      <dd>the datatype URI of the literal value (optional)</dd>
+    </dl>
+
+    <p>Blank node subjects are named using a string conforming to the nodeID production in Turtle. For example: _:A1</p>
+
+    <p>The 'lang' and 'datatype' keys should only be used if the value of the 'type' key is &quot;literal&quot;.</p>
+
+    <p>All keywords defined in this document are case sensitive, and
+    must be lowercase.</p>
