Hi Anand,
any SPIN function needs to be registered with the Jena FunctionRegistry.
The KennedysInferencingAndConstraintsExample.java shows how to do this:
// Register locally defined functions
SPINModuleRegistry.get().registerAll(ontModel, null);
*However* this only registers your SPIN functions to Jena, and with
OWLIM you may be in a situation in which the whole query is executed
server-side using the native SPARQL engine of OWLIM, bypassing any
locally registered Jena functions. In a sense Jena is just the client
then. I have not used the OWLIM Jena bridge, but you can verify if an
error is reported such as unknown function coming from OWLIM directly.
So please make sure the function is registered at all, and send us any
error message if it still happens.

I have done the bridging between OWLIM-SE and TopBraid Composer. I
have even created simple Functions and executed against OWLIM data
from TopBraid Composer.
Now I would like to call this spin function using SPIN API on OWLIM model,
*Loading model from OWLIM,*
manager = RemoteRepositoryManager.getInstance(Preferences
.getRepositoryURL());
manager.initialize();
owlimRepository =
manager.getRepository(Preferences.Common.REPOSITORY_NAME);
owlimRepository.initialize();
dataset = new SesameDataset(con);
*model* = ModelFactory.createModelForGraph(dataset.getDefaultGraph());
*Executing SPARQL*
queryFromSparqlTxt = "SELECT (
<http://spinrdf.org/spin#accountage>(30) AS ?user) {}"
QueryExecution qExec = QueryExecutionFactory.create(queryFromSparqlTxt,
*model*);
return qExec.execSelect();
Note:-
http://spinrdf.org/spin#accountage is the function defined in TopBraid
Composer and stored back to OWLIM.
Now, When I execute the SPARQL, I don't get the expected output.
Please help me on this. Am I missing any spin registry?
Thanks
Raj

Raj; The best way to do this is to download the OWLIM plug-in for
TopBraid. Then you have both an ontology editor and your back-end.
The plugin is maintained by Ontotext, so go to
http://owlim.ontotext.com/display/OWLIMv50/OWLIM-SE+Installation
to download. There is a section named "Using OWLIM-SE with
TopBraid Composer" that explains how to update the OWLIM plug-in.
If you want to execute the SPIN API as a stand-alone package, the
API documentation is complete in terms of support for the API.

Hi Thanks. I have gone through
http://www.topquadrant.com/spin/tutorial/. I even tried all the
samples and works fine for me. Now I would like to register the
spin template using SPIN API and execute at the sesame repository
(OWLIM-SE). Could you please provide me the sample code.
Thanks

Hi,
I am pretty much familiar with OWLIM, but not with SPIN.
Could anyone guide me in executing a simple select user
defined template with a filter option upon OWLIM?
Thanks in advance.
