Hello,
I am working about reasoning in Jena. I take RDF model and i enrich it.So the
RDF obtained is voluminous and to save it in a file i must wait many hours (3
or 4 hours). I thought to use TDB but i am not sure that is the best way to
resolve the problem.
Please, do you have idea?
Thanks.

Thank you for the help. But i have tried the both RDFDataMgr and RDFWriter but
the result is not better.

You didn't address these questions:

Please be specific about what you tried. Include how big your data
is [befor and after inference] and how much memory you gave

I am using OWL reasoner of Jena. But the problem is not the inference ingine.
The inference finished after 2 seconds. The probleme is whene i take resulted
Model to save it in a file.
I am trying with Jena TDB and i seems that i am in the right direction.
Thank you.

If the inference uses backwards rules, it do

Thank you Dave, effectively the materialization of the model make the writing
in file really faster.
Thanks

Hi,
I am having a little bit of trouble implementing the TDB store for my Jena
Ontologies. I have been able to solve most of the issues that I've come
across, but I have become frustrated with the view request functions that
the Ontology objects define.
I am trying to get a list of all of the res
I forgot to mention that this is happening during a Write Transaction on
the Dataset, in case that is important.

Hi,
Found that the problem was due to to trying to add a submodel and
OWL:imports statement during the same transaction. I had to finish and
commit the transaction where I add the submodel first, then start another
transaction that would read the Class Restrictions.
Sometimes I just need to expla

Hi all,
I'm wondering if someone can help me check my understanding of how ARQ

do I check which version of ARQ is in this version of Fuseki?). I'm wondering
if in the first un-optimized algebra form, this amounts t

Running Fuseki with just the --version argument will dump out the versions
of the various components to stdout
VALUES translates into the table operator which essentially provides a set
of solutions which are joined to some other part of the query. So with
the unoptimised algebra ARQ would f
