Hi Jérôme,
you are lucky, I've just exactly the same need as you and I've
something about it recently.
Unfortunately, the new LARQ (as a separate module) still did not
make it into Fuseki on trunk.
We have an open JIRA for it which you can watch|vote|contribute to:
https://issues.apache.org/jira/browse/JENA-63
In the meantime, if you want to use LARQ with Fuseki this is what
you need to do:
cd /tmp
svn co
https://svn.apache.org/repos/asf/incubator/jena/Jena2/Fuseki/trunk/
fuseki
cd /tmp/fuseki
wget
https://issues.apache.org/jira/secure/attachment/12482758/JENA-63_Fuseki_r1136050.patch
patch -p0< JENA-63_Fuseki_r1136050.patch
mvn package
Now, you can simply use the Fuseki config.ttl file as explained here:
http://openjena.org/wiki/Fuseki#Fuseki_Configuration_File
and use the ja:textIndex property on a dataset to specify an non
existing directory.
Is it possible to have a fuseki configuration example with a
ja:textIndex property? I am trying to
add it on the book service (books.ttl) with no results...
Use tdbloader to load some RDF data into /tmp/tdb, then change <#dataset>
on the example config.ttl file you have in Fuseki:
http://svn.apache.org/repos/asf/incubator/jena/Jena2/Fuseki/trunk/config.ttl
I've never used the TDB loader - How does it work? Is there an on-line
documentation?
Thanks
[...]
<#dataset> rdf:type tdb:DatasetTDB ;
tdb:location "/tmp/tdb" ;
ja:textIndex "/tmp/lucene" ;
.
If the /tmp/lucene directory does not exist, LARQ will index what you
have in
/tmp/tdb creating the appropriate Lucene indexes.

Thanks
LARQ when you point it at a non existing directory will perform the
indexing for you.
This is particularly useful when you have multiple datasets
configured in Fuseki.
WARNING: it might take a while to index large datasets, so be patient.

LARQ snapshots are here:
https://repository.apache.org/content/repositories/snapshots/org/apache/jena/larq/0.2.2-incubating-SNAPSHOT/
and I can quickly fix/improve things if you have problems or good
suggestions.
I hope this helps, let me know how it goes.

Hi,
i'm trying to use LARQ with my Fuseki server.
I would like to programmaticaly indexing(with lucene) documents
when the
server starts.
Something like that:
Model model = ModelFactory.createDefaultModel();
IndexBuilderString larqBuilder = new IndexBuilderString();
model.register(larqBuilder);
FileManager.get().readModel(model, "Data/books.ttl");
larqBuilder.closeWriter();
model.unregister(larqBuilder);
index = larqBuilder.getIndex();
LARQ.setDefaultIndex(index);
Is it possible? In which class it would be the best?
Thanks
Jerome
