Does this mean all the URIs are dbpedia.mysite.example.com rather than 
dbpedia.org/* ?

In http://kingsley.idehen.name/page/Linked_Data I see
'http://dbpedia.org/resource/Linked_Data' at the top of the page, but no 
  owl:sameAs to http://kingsley.idehen.name/page/Linked_Data

The raw data links aren't working for me at the moment:
eg.

curl 
"http://kingsley.idehen.name/sparql?default-graph-uri=http%3A%2F%2Fdbpedia.org&query=DESCRIBE+%3Chttp://kingsley.idehen.name/resource/Linked_Data%3E&output=xml"
<?xml version="1.0" encoding="utf-8" ?>
<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" 
xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#">

etc., ... but I get the impression the RDF files use the main dbpedia 
URI space, while the HTML uses local references. If that's the case, how 
might this look in RDFa?

cheers,

Dan
