Hi Andy,
Thank you for the information, I manage to do this with the following code:
“
Model spec = FileManager.get().loadModel(config);
Resource root = spec.createResource( spec.expandPrefix( rootDS ));
dataset = DatasetFactory.assemble(root) ;
“
I have a following question, rather out of curiosity, that it seems that if I
use this code, I can’t use transaction (throwing
java.lang.UnsupportedOperationException). Is there possible that model with
inference could support transaction?
If you want transactions, at least without a working .abort, you can use
DatasetGraphWithLock, which wraps another DatasetGraph with some code
provide transaction semantics (.begin/.commit/.end) using MRSW locking,
so no true parallel writer and readers.
There is some experimental code that provides .abort() as well, done by
replaying a log backwards
https://svn.apache.org/repos/asf/jena/Experimental/rdfpatch/
class DatasetGraphPatchTransaction
but that isn't integrated into truck at the moment. It should work,
it's finished except for the integration.
Andy
