Dear Kerstin,

Have you ever looked at http://linkedct.org ?

LinkedCT uses a complex process to turn ClinicalTrials.gov into
high-quality 5-start Linked Data. And yes it does provide HTTP URIs for all
the "things" on ClinicalTrials.gov, provides HTML or RDF, SPARQL endpoint,

Please take a look at http://linkedct.org , http://linkedct.org/stats/ ,
and http://linkedct.org/faq/ , and the following articles for any questions
you might have.
