Jérôme,
Sorry if you've said this before in previous emails but what's the query
and what's the data like? When did you last update LARQ?
I'm trying to find out if something in the chain of packages has changed
and whether we've introduced a a regression in ARQ or LARQ.
The only ARQ change I can think of relates to named graphs but you're
not using named graphs and the change to correctly handle property
functions would only go from 0 to some results.
You have the same data available via <#books> and via <#dataset> -- does
the query work one route and not the other or are both now showing 0
results?

Hi Jérôme,
first of all, thanks for helping out testing the LARQ 0.2.2-incubating-SNAPSHOT
and for your patience. ;-)
This hopefully will help to spot problems early one and reduce problems once ARQ
and LARQ are released within Apache.

Hi,
i've recently made an svn up on my LARQ directory.
Now, my LARQ queries return 0 solution (they returned before).
I'm using:
- fuseki 0.2.1-SNAPSHOT
-arq 2.8.9-SNAPSHOT
-larq 0.2.2-incubating-SNAPSHOT
According to the LARQ's pom.xml file [1], LARQ 0.2.2-incubating-SNAPSHOT now
depends on the new ARQ SNAPSHOTs.
Precisely, it depends on org.apache.jena:jena-arq:2.8.9-incubating-SNAPSHOT
Please note the new groupId and artifactId for ARQ.
New ARQ SNAPSHOTs are available here [2].

-lucene 3.1.0
My config.ttl file has not changed:
[...]
<#books> rdf:type ja:RDFDataset ;
rdfs:label "Books" ;
ja:defaultGraph
[ rdfs:label "discours_de_la_methode.rdf" ;
a ja:MemoryModel ;
ja:content [ja:externalContent<file:Data/file.rdf> ] ;
] ;
.
<#dataset> rdf:type tdb:DatasetTDB ;
tdb:location "/tmp/tdb" ;
ja:textIndex "/tmp/lucene" ;
# Query timeout on this dataset (milliseconds)
ja:context [ ja:cxtName "arq:queryTimeout" ; ja:cxtValue "1000" ] ;
## tdb:unionDefaultGraph true ;
Before running the fuseki server, i build my triple store with the
command-line:
java -cp target/fuseki-0.2.1-SNAPSHOT-sys.jar tdb.tdbloader
--loc=/tmp/tdb Data/file.rdf
Can you please try:
- stop Fuseki
- delete /tmp/lucence
- restart Fuseki
LARQ will now behave like this:
- if the directory exists with a Lucene index, it will leave it untouched
- if the directory does not exists it will create it and index your data
What do you have in your /tmp/lucene directory?
So, i've no error - juste 0 result...
Any ideas?
Thank you.
Let us know how it goes,
Paolo
