<p>
	When the JSON response for a SPARQL query is returned with an arbitrary ordering of object members the SparqlJsonParser may fail. Specifically, to reproduce order the &quot;results&quot; member before the &quot;head&quot; member.</p>
<p>
	&nbsp;&nbsp;&nbsp; Exception Type: VDS.RDF.Parsing.RdfParseException<br />
	&nbsp;&nbsp; &nbsp;Message: Unable to Parse a SPARQL Result Set since a Binding Object attempts to bind a value to the variable &#39;format&#39; which is not defined in the Header Object in the value for the &#39;vars&#39; property!<br />

<p>
	The specification(s) do not clarify expected order: http://www.w3.org/TR/rdf-sparql-json-res/, http://www.w3.org/TR/sparql11-results-json/. Nor does JSON clarify order, &quot;<em>An object is an unordered set of name/value pairs.</em>&quot; (http://json.org/).</p></td>
