Hello. I have been trying out some additional queries, including queries with nested GraphGraphPatterns, and have encountered some inconsistencies between fuseki and arq (both in version 5.2.0). The queries `q.rq` and `q2.rq` are executed against the dataset `data.trig`. ``` # data.trig @prefix : <http://example.org/> :graph1 { :s1 :p1 :o1 . :s1 :p2 :o2 . :s1 :p3 :o3 . } :graph2 { :s1 :p1 :o1 . :s1 :p2 :o2 . } ``` ```sparql # q.rq SELECT * WHERE { GRAPH ?g1 { { SELECT * WHERE { GRAPH ?g { ?s ?p ?o } } } } } ``` ```sparql # q2.rq SELECT * WHERE { GRAPH ?g { VALUES ?s { <http://example.org/s1> } } } ``` Results for `q.rq` ``` fuseki (note: `g1` is unbound) s,p,o,g,g1 http://example.org/s1,http://example.org/p1,http://example.org/o1,http://example.org/graph1, http://example.org/s1,http://example.org/p1,http://example.org/o1,http://example.org/graph2, http://example.org/s1,http://example.org/p2,http://example.org/o2,http://example.org/graph1, http://example.org/s1,http://example.org/p2,http://example.org/o2,http://example.org/graph2, http://example.org/s1,http://example.org/p3,http://example.org/o3,http://example.org/graph1, ``` ``` ./arq --explain --query=q.rq --data=data.trig 14:30:43 INFO exec :: QUERY SELECT * WHERE { GRAPH ?g1 { { SELECT * WHERE { GRAPH ?g { ?s ?p ?o } } } } } 14:30:43 INFO exec :: ALGEBRA (graph ?g1 (graph ?g (bgp (triple ?s ?p ?o)))) 14:30:43 INFO exec :: BGP :: ?s ?p ?o 14:30:43 INFO exec :: Reorder/generic :: ?s ?p ?o 14:30:43 INFO exec :: BGP :: ?s ?p ?o 14:30:43 INFO exec :: Reorder/generic :: ?s ?p ?o 14:30:43 INFO exec :: BGP :: ?s ?p ?o 14:30:43 INFO exec :: Reorder/generic :: ?s ?p ?o 14:30:43 INFO exec :: BGP :: ?s ?p ?o 14:30:43 INFO exec :: Reorder/generic :: ?s ?p ?o ------------------------------------------------------------------------------------------------------------------------------------------- | s | p | o | g | g1 | =========================================================================================================================================== | <http://example.org/s1> | <http://example.org/p1> | <http://example.org/o1> | <http://example.org/graph1> | <http://example.org/graph1> | | <http://example.org/s1> | <http://example.org/p2> | <http://example.org/o2> | <http://example.org/graph1> | <http://example.org/graph1> | | <http://example.org/s1> | <http://example.org/p3> | <http://example.org/o3> | <http://example.org/graph1> | <http://example.org/graph1> | | <http://example.org/s1> | <http://example.org/p1> | <http://example.org/o1> | <http://example.org/graph2> | <http://example.org/graph1> | | <http://example.org/s1> | <http://example.org/p2> | <http://example.org/o2> | <http://example.org/graph2> | <http://example.org/graph1> | | <http://example.org/s1> | <http://example.org/p1> | <http://example.org/o1> | <http://example.org/graph1> | <http://example.org/graph2> | | <http://example.org/s1> | <http://example.org/p2> | <http://example.org/o2> | <http://example.org/graph1> | <http://example.org/graph2> | | <http://example.org/s1> | <http://example.org/p3> | <http://example.org/o3> | <http://example.org/graph1> | <http://example.org/graph2> | | <http://example.org/s1> | <http://example.org/p1> | <http://example.org/o1> | <http://example.org/graph2> | <http://example.org/graph2> | | <http://example.org/s1> | <http://example.org/p2> | <http://example.org/o2> | <http://example.org/graph2> | <http://example.org/graph2> | ------------------------------------------------------------------------------------------------------------------------------------------- ``` Results for `q2.rq` ``` fuseki s,g http://example.org/s1, ``` ``` ./arq --explain --query=q2.rq --data=data.trig 14:53:59 INFO exec :: QUERY SELECT * WHERE { GRAPH ?g { VALUES ?s { <http://example.org/s1> } } } 14:53:59 INFO exec :: ALGEBRA (graph ?g (table (vars ?s) (row [?s <http://example.org/s1>]) )) --------------------------------------------------------- | s | g | ========================================================= | <http://example.org/s1> | <http://example.org/graph1> | | <http://example.org/s1> | <http://example.org/graph2> | --------------------------------------------------------- ``` Based on the previous responses, the results returned from arq are correct for both queries, right? -- This is an automated message from the Apache Git Service.
