Hi,
I have registered the function, as suggested
registry.registerAll(model, null);
Function function =
registry.getFunction("http://spinrdf.org/spin#accountage";, model);
SPINARQFunction spinarqFunction = new SPINARQFunction(function);
I get the function too. Now I need an example how to execute this
function using *exec* or *executeBody methods. *I am struck with
supplying arguments to methods. How do I create variables and assign
value to it.
It would be of great help, if you could share me the sample code.
Thanks
Raj

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.
