Re: [Owlim-discussion] Context mixing with Jena API and OWLIM-SE

[Ing. Marek Smid]

Hello,

unfortunatelly, the problem persists.
When I store different data data to different contexts, they accumulate 
(and clearing does not work).
Assume I have the code I mentioned earlier to connect to 
LocalRepositoryManager, and this piece of code for storing to different 
contexts:


for (String context : contexts) {
    Model inm = in.getModel(context);
    Model outm = out.getModel(context);

    if (outm.supportsTransactions()) outm.begin();
    outm.removeAll();
    if (outm.supportsTransactions()) outm.commit();

    logger.info("Model after clearing: " + context + " in size = " + 
inm.size() + ", out size = " + outm.size());

    if (outm.supportsTransactions()) outm.begin();
    outm.add(inm);
    if (outm.supportsTransactions()) outm.commit();

    logger.info("Model after loading: " + context + " in size = " + 
inm.size() + ", out size = " + outm.size());

    in.closeModel(inm);
    out.closeModel(outm);
}


Where "in" and "out" are my own connectors providing Jena Models. Input 
is another Jena repository (currently SDB), and output is the OWLIM 
repository.

With a clear OWLIM storage folder, the code outputs:

Model after clearing: http://.../mondis-core-data.owl in size = 1591, 
out size = 0
Model after loading: http://.../mondis-core-data.owl in size = 1591, out 
size = 1591

Model after clearing: http://.../mondis-translation.owl in size = 1922, 
out size = 1591
Model after loading: http://.../mondis-translation.owl in size = 1922, 
out size = 3513

Model after clearing: http://mondis.cz/ in size = 1587, out size = 3513
Model after loading: http://mondis.cz/ in size = 1587, out size = 3517


Am I doing something wrong, please?

Thanks for any help,
Marek Smid

Hi Barry,

thank you, that explains it. Yes, I am using
com.ontotext.jena.SesameDatase, but as you already know, with a remote
repository. I will use local instead.

Best regards,

Hi Marek,

Sorry for the slow response, the holiday period is slowing things up.

In your code below, it's not clear if you are using the
com.ontotext.jena.SesameDataset, which is the OWLIM Jena adapter. This
adapter will only work with local OWLIM repositories, i.e. not those
that are obtained via the RemoteRepositoryManager.

Please advise if you are using a different SesameDataset class.

Thanks for your patience,

Hello,

I am using OWLIM-SE 5.2.5331 with both Sesame 2.6.8 and 2.6.9, and I
am having troubles with storing in different contexts.

I am using Jena API for accesing the repository, connecting remotely
like this:
RepositoryManager repoManager = new RemoteRepositoryManager(serverUrl);
repoManager.initialize();
Repository repo = repoManager.getRepository(repositoryId);
RepositoryConnection repoConnection = repo.getConnection();
repoConnection.setAutoCommit(true);
SesameDataset dataset = new SesameDataset(repoConnection);

And then, for each context, I do:
ModelFactory.createModelForGraph(dataset.getGraph(Node.createURI(ctxURI)));



But it seems it uses only the default graph (default context), all
data are stored in one heap.

However, it works well with remote connection just to Sesame (without
OWLIM).

Am I doing anything wrong?

Thank you for any help,
Marek Smid
