  ]
}

while jena (and graphDB, etc.) does this:

$ ~/Downloads/apache-jena-4.10.0/bin/rsparql --results=json --service https://query.wikidata.org/sparql --query /tmp/q2.rq 
{ "head": {
    "vars": [ "p" , "o" ]
  } ,
  "results": {
    "bindings": [
      { 
        "p": { "type": "uri" , "value": "http://wikiba.se/ontology#rank" } ,
        "o": { "type": "uri" , "value": "http://wikiba.se/ontology#NormalRank" }
      } ,
      { 
        "p": { "type": "uri" , "value": "http://www.w3.org/1999/02/22-rdf-syntax-ns#type" } ,
        "o": { "type": "uri" , "value": "http://wikiba.se/ontology#BestRank" }
      } ,
      { 
        "p": { "type": "uri" , "value": "http://www.wikidata.org/prop/statement/P8988" } ,
        "o": { "type": "literal" , "value": "osm&id=276" }
      }
    ]
  }
}

the way basil currently does it it makes it harder to just get the value. e.g.

{ ... "some_number":"1029^^http://www.w3.org/2001/XMLSchema#integer" ... }

while jena does:

        "some_number" : {
          "datatype" : "http://www.w3.org/2001/XMLSchema#integer",
          "type" : "literal",
          "value" : "1029"
        }
