This is a survey to help understand how people use the term "named graph" and what they mean by it. The questions are not meant to be tricky or hard, just to find out how you understand them. If you don't know the answer, please just say so, without trying to look it up.

All the questions use Turtle/SPARQL syntax and assume the empty prefix is bound to <http://example.org/>. This means, for example, that :a expands to the RDF term <http://example.org/a>, and that { :a :b 1 } stands for the RDF Graph that would be written in n-triples as:

   <http://example.org/a> <http://example.org/b> "1"^^<http://www.w3.org/2001/XMLSchema#integer> .

The questions are all about one dataset, written in TriG as follows. If you don't know TriG, take your best guess what it means.

   @prefix : <http://example.org/>.
   { :a :b 1 }       # the default graph
   :g1 { :a :b 10 }
   :g2 { :a :b 20 }
   :g3 { :a :b 10 }

All questions are optional.
