Some time ago I posted a compromise dataset design that offered most of
the features of rq23, but with fewer requirements on the implementation:
http://lists.w3.org/Archives/Public/public-rdf-dawg/2005JanMar/0440.html
[its quite long an rambling, so I dont suggest you read it]
Anyway, Andy and I have been duiscussing it on IRC, and he requested a
testcase:
dataset:
a.rdf:
:x :prop "1" .
b.rdf:
:x :prop "2" .
c.rdf:
:x :prop "3" .
a.rdf and b.rdf are the default graph set (n.b. there is no
anonymous graph).
query:
SELECT ?z WHERE { ?x ?y ?z . }
result:
-------
| ?z |
-------
| "1" |
| "2" |
-------
query:
SELECT ?g ?z WHERE { GRAPH ?g { ?x ?y ?z . } }
result:
-----------------
| ?g | ?z |
-----------------
| <a.rdf> | "1" |
| <b.rdf> | "2" |
| <c.rdf> | "3" |
