Concerning the LOD data sets, we are not using SPARQL endpoints due their relative unreliability.8 Instead, we downloaded some dumps and put them on our own OpenRDF Sesame triple store. We are using the phpSesame PHP Client library which enables us to access OpenRDF’s Sesame Framework via HTTP requests. All non-RDF data, i.e., list of mild clinical signs, molecules and their ratings as well as pharmacy coordinates, are stored in a MySQL database instance to support a faster and easier integration with our French system.
