Tim,
The assembler file has
tdb:unionDefaultGraph true ;
in it; no idea why. The real default graph is loaded with the example data.
The example query uses
?s text:query (rdfs:label 'X1') ;
rdfs:label ?label
so it is accessing the default graph at rdfs:label -- no matches, no
results.
Remove the tdb:unionDefaultGraph - also try with out the rdfs:label to
show the index does return something.

Hi all,
I was playing around with the new jena-text module. I downloaded from svn the
jena-2.11.0 tag and ran the JenaTextExample1 example. It failed with the
following error:
Exception in thread "main" org.apache.jena.riot.RiotNotFoundException: Not
found: data.ttl
this was simple to fix as the issue was that there was no data.ttl file in the
root of the jena-text module. So I created one that looks like so:
@prefix : <http://localhost/jena_example/#> .
@prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> .
:T1 rdfs:label "X0 X1 X2" .
:T2 rdfs:label "X10 X11 X12" .
I then ran it again to get the following result:
----------------------------------------------------
| s | label |
====================================================
| <http://localhost/jena_example/#T1> | "X0 X1 X2" |
----------------------------------------------------
Now I simply changed lines 46-47 from:
Dataset ds = createCode() ;
//Dataset ds = createAssembler() ;
to:
//Dataset ds = createCode() ;
Dataset ds = createAssembler() ;
and run it again to get:
-------------
| s | label |
=============
-------------
I looked at the assemble file and don't really see any issues with it. It
should just be creating a DatasetTDB for the dataset, rather than the
createCode() method's choice to build a dataset via DatasetFactory.createMem()
Any help appreciated.
Thanks,
Tim
