I just downloaded the latest snapshot of Fuseki 0.2.8 this morning
(revision 1496155 from the trunk) . I'm using config-tdb-text.ttl,
(attached) which has tdb:unionDefaultGraph set to true. I start Fuseki
with:
/usr/bin/java -Dlog4j.configuration=log4j.properties -Xmx3200M -jar
/opt/jena-2.10/jena-fuseki-0.2.8-SNAPSHOT/fuseki-server.jar --update
--config=config-tdb-text.ttl --port=3131
If I add any data to the triple store, whether I put it in a named graph
or not, and then attempt to query it without specifying a graph, I don't
get any results.
If I query with this:
select * where { graph <urn:x-arq:UnionGraph> { ?s ?p ?o } }
I do get results, which implies that the unionDefaultGraph option I set
in my .ttl assembler isn't working correctly.
Anyone have any ideas why the unionDefaultGraph capability isn't working?
Thank you,

Elli,
Thanks for the report. I've recorded this as JENA-477.
I think I understand what is (or in this case, is not) going on. It's a
design issue in that the query is executing over the dataset abstraction
for text datasets, and so not deciding to use the TDB execution engine
at the right granularity. Fix in progress.
