#19 RDFAPI error (class: parser)

[Agentk]

Hi,

I want to parse the file rdf :
<c:component xmlns:c="http://www.w3.org/2002/12/cal/icaltzd#">
<c:Vevent r:about="#hcalendar-event-title" xmlns:r="http://www.w3.org/1999/02/22-rdf-syntax-ns#">
<c:summary>event title</c:summary>
<c:dtstart r:datatype="http://www.w3.org/2001/XMLSchema#date">20070320</c:dtstart>
<c:dtend r:datatype="http://www.w3.org/2001/XMLSchema#date">20070321</c:dtend>
<c:url r:resource="#hcalendar-event-title"/>
</c:Vevent>
</c:component>

I checked the file in the W3C RDF parser : it's OK.
http://www.w3.org/RDF/Validator/

Code :
$parser = new RdfParser();
$model = $parser->generateModel($_FILES["rdffile"]["tmp_name"]);

Errors :
Warning: RDFAPI error (class: parser): unknown rdf attribute: about. in W:\www\wp-content\plugins\myavatar\rdfapi-php\api\syntax\RdfParser.php on line 1045

Warning: RDFAPI error (class: parser): only one element allowed inside a property element. in W:\www\wp-content\plugins\myavatar\rdfapi-php\api\syntax\RdfParser.php on line 1045

Bye
