That is a Web Page in front of a SPARQL service scoped to specific datasets. Here's a set of commands (for Unix, Linux, or macOS) that a SPARQL endpoint for the SPARQL Protocol would handle: echo " select distinct ?o where {?s a ?o} limit 100" > sparql-query.rq ; cat sparql-query.rq ; QUERY=$(<sparql-query.rq) && curl -X POST -H "Accept: text/html" --data-urlencode "query=$QUERY" http://linkeddata.uriburner.com/sparql ; QUERY=$(<sparql-query.rq) && curl -X POST -H "Accept: application/sparql-results+xml" --data-urlencode "query=$QUERY" http://linkeddata.uriburner.com/sparql ; QUERY=$(<sparql-query.rq) && curl -X POST -H "Accept: text/html" --data-urlencode "query=$QUERY" http://sage.univ-nantes.fr/sparql/dbpedia-2016-04 ; QUERY=$(<sparql-query.rq) && curl -X POST -H "Accept: application/sparql-results+xml" --data-urlencode "query=$QUERY" http://sage.univ-nantes.fr/sparql/dbpedia-2016-04 ; > On Sat, 8 Sep 2018 at 20.38, Kingsley Idehen <kidehen@openlinksw.com > <mailto:kidehen@openlinksw.com>> wrote: > > On 9/8/18 2:31 PM, Kingsley Idehen wrote: >> On 9/8/18 4:23 AM, Pascal Molli wrote: >>> Dear Kingsley, >>> >>> We detail how, and in which context, we achieved the SaGe result in: >>> >>> Thomas Minier, Hala Skaf-Molli, Pascal Molli.
