[Attempto] OWL verbalizer in ACE converter ERROR!

[Kiavash Bahreini]

Dear ACE,
 
I am trying to convert the below links into "OWL 2
XML" as "ACE feed" through this link (http://owl.cs.manchester.ac.uk/converter)
 
http://slashdot.org/slashdot.rdf and http://slashdot.org/slashdot.xml  and http://rss.slashdot.org/Slashdot/slashdot 
 
After executing the convert button, I get the error below for “http://slashdot.org/slashdot.rdf”,
specially by selecting the OWL/XML and RDF/XML radio buttons.
 "The XML page cannot be
displayed Cannot view XML input using XSL style sheet. Please correct the error
and then click the Refresh button, or try again later.
The namespace prefix is not allowed
to start with the reserved string "xml". Error processing resource
'http://owl.cs.manch...
     xmlns:xml="http://www.w3.org/XML/1998/namespace"
-----^"
 
and the error below by choosing " http://slashdot.org/slashdot.xml ". 


Problem parsing http://slashdot.org/slashdot.xml
Could not parse ontology.  Either a suitable parser could not be found,
or parsing failed.  See parser logs below
for explanation.
The following parsers were tried:
1) RDFXMLParser
2) OWLXMLParser
3) OWLFunctionalSyntaxOWLParser
4) TurtleOntologyParser
5) OWLOBOParser
6) KRSS2OWLParser
7) ManchesterOWLSyntaxOntologyParser
 
Detailed logs:
--------------------------------------------------------------------------------
Parser: RDFXMLParser
org.semanticweb.owlapi.rdf.syntax.RDFParserException:
[line=2:column=53] Expecting rdf:RDF element.
--------------------------------------------------------------------------------
Parser: OWLXMLParser
Unkown element type: backslash (Line
2)(Current element backslash)
....

Then
try to run OWL verbalizer through http://attempto.ifi.uzh.ch/site/docs/owl_to_ace.html and the sample of OWL 2 tags inside the page, but received two types of errors as
follow:

Proxy Error
The proxy server received an invalid response from an
upstream server.
The proxy server could not handle the request POST
/service/owl_verbalizer/owl_to_ace.
Reason: Document contains
no data
Or
Reason: Error reading from
remote server

Any Suggestions?  I
looked via documentation and the mailing list, but couldn't find anything that addressed the problem.
 
Cheers,
Kiavash
