     10A first cut at recursive queries is working. At the moment, only 
     11in-memory recursive queries are working; we do not yet pass the query 
     12down to our SQL model.  A sample query is: 
     13 
     14PREFIX  xsd:    <http://www.w3.org/2001/XMLSchema#> 
     15PREFIX  mar:    <http://localhost/mar/> 
     16PREFIX  :       <.> 
     17 
     18SELECT * 
     19FROM <tc> [ CONSTRUCT { ?a ?b ?c } 
     20            FROM <graph0.ttl> 
     21            WHERE { ?a ?b ?c } 
     22 
     23            UNION 
     24 
     25            CONSTRUCT { ?a ?b ?d } 
     26            FROM <tc> 
     27            FROM NAMED <graph0.ttl> 
     28            WHERE { ?a ?b ?c . 
     29                    GRAPH <graph0.ttl> {?c ?b ?d .} 
     30                  } 
     31            ] 
     32WHERE { ?x ?y ?z }
