Thank you Osma,
It works fine, I only had to replace /sparql with /ds/query.
Best Regards,
Sandor

Hi Sandor,
You need to do a federated query. See the SPARQL 1.1 Query spec.
Something like this:
SELECT *
WHERE {
SERVICE <http://other-endpoint/sparql> {
GRAPH <http://uri-of-graph> {
?s ?p ?o
}
}
}

Dear list-member,
I have two Fuseki servers running on two different machines. In one of
them there are several named graphs containing a lot of concepts.
I would like to run a query from another Fuseki server to select all (or
later just some) triplets from this dataset using a query like this:
SELECT *
FROM </URL of the SPARQL endpoint/:3030/ds/query>
WHERE {GRAPH </URI of the graph/>
{?s ?p ?o . }
}
but it provides empty set:
-------------
| s | p | o |
=============
-------------
What is wrong?
Thanks in advance,
Sandor
