Hi Sergio,
Attempting to load you sample data into a VOS 5.0.11 server fails
with the error:

Which I presume is the error you refer to ???
Whereas testing against one of our latest builds this data does load
and can be queried:

So it would appear the issues has already been inherently resolved ...

You aren't using valid RDF/XML.
Why? While you don't give me details, I don't find why this
serialization is not valid...
Let's put a concrete example of the conflictive peace of code:
<?xml version="1.0"?>
<rdf:RDF
xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#";
xmlns:foaf="http://xmlns.com/foaf/0.1/";>
<foaf:Person rdf:about="http://example.org#person";
rdf:type="http://xmlns.com/foaf/0.1/Agent";>
<foaf:name>Person Example</foaf:name>
</foaf:Person>
</rdf:RDF>
That is completelly valid RDF/XML accoding W3C recommendation, and
works
fine with W3C validator and several parsers, not with Virtuoso. So I
guess we can say that this is a bug in the parser.
Best regards,
