Abstract SPARQL Endpoint to allow browsing the data stored through the LD4S API (http://spitfire-project.eu/incontextsensing/apiDocumentation.php). Please submit a POST request to http://spitfire-project.eu:8182/ld4s/sparql with the SPARQL query included in a JSON field labelled "query".
Example: curl --request post --data '{"query": ["PREFIX spt: SELECT * {GRAPH ?g {?x a ?t}}"]}' --header "Accept: application/rdf+xml" --header "Content-type: application/json" http://spitfire-project.eu:8182/ld4s/sparql
Please, note that the data in the Triple Store is organized into named graphs. Consequently, you need to address specific named graphs in your query in order to access the stored triples (e.g., select ... where { graph ?namedGraphURI {...} }). The above example will let you discover which are all the available named graph URIs.
