Hello, I have container resources which I want to retrieve from one of their elements. Here is an RDF/XML part of my data:
<rdf:Description rdf:about=" http://www.telemis.com/CalculationResult/9e892a88-7257-4af3-881d-2eb304437546 "> <rdf:type rdf:resource="http://www.telemis.com/CalculationResult"/> <TM:uid rdf:datatype="http://www.w3.org/2001/XMLSchema#string ">9e892a88-7257-4af3-881d-2eb304437546</TM:uid> ... </rdf:Description> <rdf:Description rdf:nodeID="A525"> <rdf:type rdf:resource="http://www.w3.org/1999/02/22-rdf-syntax-ns#Seq"/> <rdf:_1 rdf:resource=" http://www.telemis.com/CalculationResult/9e892a88-7257-4af3-881d-2eb304437546 "/> <rdf:_2 rdf:resource=" http://www.telemis.com/CalculationResult/9e892a88-7257-4af3-881d-45208e34af13 "/> </rdf:Description> <rdf:Description rdf:about=" http://www.telemis.com/CalculationResultCollection/a7d808d7-7689-4dfb-82c4-b0763f0dcd34 "> <rdf:type rdf:resource="http://www.telemis.com/CalculationResultCollection "/> <TM:uid rdf:datatype="http://www.w3.org/2001/XMLSchema#string ">a7d808d7-7689-4dfb-82c4-b0763f0dcd34</TM:uid> <TM:listCalculationResult rdf:nodeID="A525"/> </rdf:Description> The representation of this context could be: (CalculationResultCollection) --listCalculationResult--> (seq-blank-node) +--(rdf:_1)-->(CalculationResult1) +--(rdf:_2)-->(CalculationResult2) +--... I've a SPARQL query which gives me a set of CalculationResult nodes. My question is: by which SPARQL query can I trace back to the CalculationResultCollection containing resource(s) ? Here is the SPARQL query which gives me a set of CalculationResult nodes: PREFIX : <http://www.telemis.com/> 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#> SELECT ?calculationResult WHERE { ?calculationData a :CalculationData ; :value "0"^^xsd:string . ?seqCalculationDataCollection ?seqCalculationDataCollectionIndex ?calculationData . ?calculationDataCollection a :CalculationDataCollection ; :listCalculationData ?seqCalculationDataCollection . ?calculationResult a :CalculationResult ; :calculationDataCollection ?calculationDataCollection . } I tried to complete my WHERE clause with statements like I did to trace back to ?calculationDataCollection from ?calculationData but I cannot get the wanted result because the system freezes. Note that the SPARQL query here above returns good results. Is there a better practice to do that with acceptable performances ?
