Thanks. I updated my TDB installation and my application's jena dependencies to jena-arq 2.9.2 and jena-tdb 0.9.2 from 2.9.0-incubating and 0.9.0-incubating and that seems to have resolved the issue. --Stephan On Jul 12, 2012, at 4:03 PM, Andy Seaborne wrote: > On 12/07/12 17:48, Stephan Zedn

Re: Multiple Bindings for single value

Rob, >> model.createTypedLiteral(new Long(ii))); That puts in a typed literal as xsd:long, because xsd:long reflects all the range limitations of a Java Long. Try putting in a xsd:integer with: m.createTypedLiteral("0", XSDDatatype.XSDinteger) ; because it looks like inference is inferring

Re: Multiple Bindings for single value

Update: I found that a small change is making the difference. It seems that the combination of* *axioms within my model and the language spec used when creating it are causing the duplication to occur. The following list denotes the base spec that I used when creating my reasoner; whether or not my

LARQ query with GRAPH clause

Hi, We've noticed that this (unionDefaultGraph = true) query: SELECT ?subject ?predicate ?object ?score WHERE { (?object ?score) "cruise" . ?subject ?predicate ?object . } ORDER BY Desc(?score) runs significantly faster (i,e., 100x) t

Multiple Bindings for single value

Hey, I have an OntModel with an attached pellet reasoner that I am querying with ARQ. It contains typed literals (for example, *"0"^^< http://www.w3.org/2001/XMLSchema#long>*) which I've added directly using the typed literal api as follows: *model.add(individual, Vocabulary.atIndex, model.cre

LARQ prefix search results missing hits

Hello! I'm trying to use a Fuseki SPARQL endpoint together with LARQ to create a system for accessing SKOS thesauri. The user interface includes an autocompletion widget. The idea is to use the LARQ index to make fast prefix queries on the concept labels. However, I've noticed that in some s
