Hi list, Moving on to expose different entities within a given RDF dataset, I am trying to construct a query to retrieve individuals and their associated numeric values. Some sample data is as follows
### http://www.semanticweb.org/ontologies/2010/11/section6energydomestic2010.owl#exampleGlazingToConservatory section6energydomestic2010:exampleGlazingToConservatory rdf:type section6energydomestic2010:Glazing , owl:NamedIndividual ; section6energydomestic2010:hasMaximumAreaWeightedAverageUvalueForAllElementsOfTheSameTypeWperm²K "2.0"^^xsd:double ; section6energydomestic2010:hasMaximumIndividualElementUvalueWperm²K "3.3"^^xsd:double . I am confused as to how to construct my query, so far I have PREFIX xsd: <http://www.w3.org/2001/XMLSchema#> PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> PREFIX owl: <http://www.w3.org/2002/07/owl#> PREFIX fn: <http://www.w3.org/2005/xpath-functions#> PREFIX apf: <http://jena.hpl.hp.com/ARQ/property#> PREFIX dc: <http://purl.org/dc/elements/1.1/> PREFIX ns: <http://www.semanticweb.org/ontologies/2010/11/section6energydomestic2010.owl#exampleGlazingToConservatory/> SELECT ?type ?NamedInidividual ?b ?double WHERE { ?b rdf:type ?type; owl:NamedIndividual ?NamedIndividual; xsd:double ?double . FILTER (?double < 2.5)} Although again the syntax is valid, I am getting no results as the query is not correctly constructed. I would like to get something like Glazing | exampleGlazingToConservatory | hasMaximumAreaWeighted...blahblah | 2.0 Thanks for any help on this one.
