Hi,
I am issuing the following SPARQL query against
http://linkeddata.uriburner.com/sparql.
define get:soft "soft"
prefix foaf: <http://xmlns.com/foaf/0.1/>
select distinct ?primaryTopic
from <http://shopper.cnet.com/cell-phones/lg-env-touch-verizon/4014-6454_9-33665903.html?tag=contentMain;contentBody
where
{
<http://shopper.cnet.com/cell-phones/lg-env-touch-verizon/4014-6454_9-33665903.html?tag=contentMain;contentBody
foaf:primaryTopic ?primaryTopic .
?primaryTopic a gr:ProductOrService .
}
The query is POSTed and sparql XML results is requested. The
response I get is:
<sparql xmlns="http://www.w3.org/2005/sparql-results#";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://www.w3.org/2001/sw/DataAccess/rf1/result2.xsd
">
<head>
<variable name="primaryTopic"/>
</head>
<results distinct="false" ordered="true">
<result>
<binding name="primaryTopic"><literal>http://
linkeddata.uriburner.com/about/id/http/shopper.cnet.com/cell-phones/
lg-env-touch-verizon/4014-6454_9-33665903.html?
tag=contentMain;contentBody</literal></binding>
</result>
</results>
</sparql>
Looks nice. That's the result I was expecting.
But... notice something wrong?
The binding contains a <literal> tag instead of <uri>.
I tried to reproduce the bug via the web interface ( choosing XML as
the result type by manipulating the combo-box ) with no luck. ( it
returns a result with the correct <uri> tag ).
I attach the complete request that yields the incorrect response
below:
