Sorry I meant SPARQL 1.1 Federated Query spec:

Hi Sandor,

You need to do a federated query. See the SPARQL 1.1 Query spec.
Something like this:

  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:

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,
