Question

where can i download the rdf/owl/nt data files? (About the healthcare or medical rdf resource will be better) I want to make use of the public RDF data files making some testing for SOR system.

Answer 1

A good Google term to help you search for available RDF datasets is linked data. For example, a list of freely available datasets which include downloadable RDF dumps is here:

http://www.w3.org/wiki/DataSetRDFDumps

linked from the index at linkeddata.org

Answer 2

A good place to start is the CKAN Data Hub, Linked Open Data (LOD) cloud, allows for topic-based browsing, informs about access methods (dump, SPARQL endpoint, etc.) and usage rights.
