after using local rdf xml file, i got this error

code is

$graph = new EasyRdf_Graph(); 

     $graph->parseFile("profile.rdf"); 

$graph->load();

$me = $graph->primaryTopic();

echo "My name is: ".$me->get('fd:name')."\n";

Hello Rabia,

$graph->load() is used to download RDF from a URL - it is not needed when parsing a local file.

$graph->parseFile("profile.rdf") will do what you need it to do.

Without seeing the contents of profile.rdf is is hard to know exactly what is going wrong.

However 'fd' is not a standard namespace that EasyRDF knows about.

There is a list of default namespaces in RdfNamespace.php:

Maybe you meant to use foaf?

nick.
