Hi Allan,
The are various ways to send curl commands to Virtuoso to perform SPARQL /
SPARUL queries like:
curl --request POST 'http://localhost:8890/sparql/?' --data-urlencode
'query=select * from <http://example.org> where {?s ?p ?o} limit 5’
cat query.rq
select * from <http://example.org> where {?s ?p ?o} limit 5
curl --request POST http://localhost:8890/sparql --data-urlencode
"format=csv" --data-urlencode [email protected]
curl --request POST 'http://localhost:8890/sparql-auth/?' --digest
--user dba:dba --data-urlencode 'query=INSERT INTO GRAPH <http://example.org> {
<1> <2> <3> }'
