We (Agfa HealthCare) are doing a project on European level around 
infectious diseases. We collect data in different hospitals (with 
different CIS systems), we data mine the retrieved results sets , store 
the results in a knowledge repository and use this knowledge for decision 
support.
The data collection, mentioned above is using sparql and a domain ontology 
we created. Having the results of the different hospitals in the same 
formalism and using the same ontologies ensure semantic interoperability 
and makes the merging of the results sets very easy.
The whole thing creates what we call a " virtual clinical data repository" 
because we don't have to centrally store clinical data. Each clinical site 
implemented a sparql endpoint, hiding the intrinsics of the specific site
We use D2R to convert from sparql to sql..

The site of our project is www.debugit.eu
Unfortunately there is no much technical detail on that site.

Is there going to be an RDF model based Linked Data View over this data? 
Or are you looking for help re. Linked Data publishing etc?
