> Key: JENA-1002
> URL: https://issues.apache.org/jira/browse/JENA-1002
> Project: Apache Jena
> Issue Type: Bug
> Components: Fuseki
> Affects Versions: Fuseki 2.0.0
> Reporter: Marvin Frommhold
>
> When I execute a query specifying a {{FROM}} clause, the result set still returns the content of the unnamed default graph.
> My test data:
> default graph
> {code}
> <http://example.org/graph1> rdfs:label "Graph1" .
> <http://example.org/graph2> rdfs:label "Graph2" .
> {code}
> http://example.org/graph1
> {code}
> <urn:subject1> rdfs:label "Subject one" .
> {code}
> http://example.org/graph2
> {code}
> <urn:subject2> rdfs:label "Subject two" .
> {code}
> The test query:
> {code}
> SELECT *
> FROM <http://example.org/graph1>
> WHERE {
> ?s ?p ?o .
> }
> {code}
> The result set:
> {code}
> s,p,o
> http://example.org/graph1,http://www.w3.org/2000/01/rdf-schema#label,Graph1
> http://example.org/graph2,http://www.w3.org/2000/01/rdf-schema#label,Graph2
> {code}
> which is the content of the unnamed default graph. This is against the specification:
> {quote}
> a default graph consisting of the RDF merge of the graphs referred to in the FROM clauses
> {quote}
