Hi Cristian,
let me explain what is causing this weird behavior - when you create a
repository through the sesame console, you are doing it so by using a template
file -bigowlim.ttl - but it uses a 'non-default' value (owlimTest-storage to be
exact) as a 'default' for the 'storage-folder' config parameter.
If you open that template file -you'll see something like :
owlim:storage-folder {%Storage folder|owlimTest-storage%} ;
where first part (before '|' ) is the hint used by the console and the second
part is the default value used wehen you just press enter.
So at the end, it will create a subfolder under the
ADUNA_OPENRDF_HOME/repositories/repository-id named after that value, e.g:
ADUNA_OPENRDF_HOME/repositories/repository-id/owlimTest-storage
But the Jena bridge uses the OWLIM's default value (because that parameter is
it not set explicitely by the configuration, specified within the joseki's
config file) and OWLIM ends configured to use a different subfolder -e.g.
'owlim-storage' - which is the default value used when no such is provvided.
So the location where the BigOWLIM indices are stored/looked up/ became:
ADUNA_OPENRDF_HOME/repositories/repository-id/owlim-storage
Long story-short - to overcome this subfolder mismatch - add the same value
that was used while the repository was initially created to the
'storage-folder' parameter within your josekiconfig.ttl e.g. - in such a way
that you end up having:
otjena:bridge http://www.ontotext.com/trree/owlim#storage-folder
owlimTest-storage .
statement as part of the joseki ttl's config - e.g. your BigOWLIM dataset
configuration should looks like (just put the actual location correctly at the
end):
## Initialize BigOWLIM
[] ja:loadClass com.ontotext.jena.SesameVocab .
otjena:DatasetSesame rdfs:subClassOf ja:RDFDataset .
otjena:bridge rdf:type otjena:DatasetSesame ;
rdfs:label BigOWLIM repository ;
http://www.ontotext.com/trree/owlim#storage-folder owlimTest-storage ;
otjena:datasetParam C:/OpenRDF Sesame/repositories/bigowlimTest .
or as an alternative, you may use the default one, while creating the
repository by simply change the template file or type it explicitly during its
creation
sorry for that inconvenience,
regards,

Subject: [Owlim-discussion] Question on Joseki Settings
Hi,
I am trying to setup bigowlin to work with Arq through Joseki as I need
Sparql1.1
I followed the instructions in Section 2.3 of the Jena Adapter document.
But it appears to be completely ignoring what I put in the line
otjena:datasetParam ./location .
No matter what I put there When I run the query
SELECT DISTINCT ?graph
{
GRAPH ?graph {
}
}
I alayws get the result:
http://www.ontotext.com/explicit
Same query from http://localhost:8080/openrdf-workbench/ gets me the correct
uploaded graph.
My Questions are:
1. What value should I put as ./location?
2. Does it matter that I am using more recent Jena than the document did?
ver.jena2.6.4/ver.jena
ver.arq2.8.7/ver.arq
ver.tdb0.8.9/ver.tdb
ver.sdb1.3.3/ver.sdb
ver.joseki3.4.3/ver.joseki
Same Sesame and Lucene versions as the bigowlin download
Thanks
Christian
PS.
Yes I did do create bigowlin from the sesameConsole as suggested in the Start
quide
Yes I did try the created folder in
C:/Users/Christian/AppData/Roaming/Aduna/OpenRDF%20Sesame/repositories/
