Re: [Bigdata-developers] sparql: combining union, graph, construct

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

I think I see several issues in this case (this is using 1.3.2 rather than the current code base)

- Jean-Marc should have separated the two load requests with a ;
- if using the nano sparql server and the web ui, 500 errors do not appear to get reported, so the problem with the lack of a ; was not reported properly
- the implementation of LOAD URL INTO GRAPH URI ignores the graph name part and always loads into the default graph
- the optimizer crashes on 
   GRAPH URI {
    ?s ?p ?o
   }
   where there are no triples in the graph …

Stack trace for last part
