How to load OntModel including imported sub-models to TDB?

Hi All, I want to load an ontology file to persistent TDB store. The ontology file imports other ontologies that are also located in the same local directory. The code is as follows: .. Dataset dataset = TDBFactory.assembleDataset(assemblerFile); dataset.begin(ReadWrite.WRITE); try { Model

Has anyone loaded freebase dump to TDB successfully?

I used to try but failed (due to some format errors). Now I want to try again? Do I have a chance to succeed? Thanks Tao

Fuseki on Google App Engine

Mostly through economic necessity, I finally got around to playing with the G thing. As far as I can tell it should be possible to host instances of Fuseki there (for free for a big starters, only $$$ if you start really hitting the bandwidth/processing). Had to jump through a few silly hoops

Re: Creating Dataset from loaded TDB and text index

I am not sure what I should be using as the second parameter for DatasetFactory.assemble. Should I use the URI provided in the documentation, or do I use the location of my own text dataset (my luceneIndex?). Either way I receive an error. If I use the URI provided, I get:

Binding Variables for sparqlService

Hi Guys I noticed the documentation states* QuerySolutionMap initialBinding = new QuerySolutionMap();initialBinding.add(name, personResource);qe = QueryExecutionFactory.create(query, dataset, initialBinding);* * * *This is often much simpler than the string equivalent since you don't have to

Re: Creating Dataset from loaded TDB and text index

Ok this issue seems to be resolved. I had to change the location of the tdb in the assembler file. NetBeans only needed the tdb location from the project folder where as from bash I needed the full file system location. Thanks again for all your help! On Thu, Aug 22, 2013 at 12:23 PM, Andy

Re: Binding Variables for sparqlService

Thanks Rob Can I follow up with a couple more questions? 1. I presume ParamaterizedSparqlString is like a query and can be used in QueryExecutionFactory.create() as the query? On Thu, Aug 22, 2013 at 5:27 PM, Rob Vesse rve...@yarcdata.com wrote: See ParamaterizedSparqlString -

Re: Binding Variables for sparqlService

Thanks Joshua Very helpful I saw the the code from 3 weeks ago. I thought that was neat. But I'm presuming that won't work for parameterisedsparqlstring. And I need to use this for a sparql service clause. So I guess I willI have to just iterate over the bindings I want to happen, rather than put

Re: Binding Variables for sparqlService

Hi Guys Sorry for asking one last dumb question Is ParameterizedSparqlString the preferred way to do variable bindings in all scenarios? I ask because I'm not sure if there are performance gains to be had using the query.setValuesDataBlock or QueryExecutionFactory.create(query, dataset,

I did further investigations and found the following implementation in RDFDataMgr works for our use cases: private static ContentType determineCT(String target, String ctStr, Lang hintLang) { if ( hintLang != null ) return hintLang.getContentType() ;
