Re: Not quite crossing the pons asinorum of construct

[Benson Margulies]

My slight variation on your last reply returns all tuples in the data
with arq. Query:

REFIX rex:   <http://www.basistech.com/ontologies/2010/6/rex.owl#>
PREFIX owl:   <http://www.w3.org/2002/07/owl#>
PREFIX x-arq: <urn:x-arq:>
PREFIX rdfs:  <http://www.w3.org/2000/01/rdf-schema#>

CONSTRUCT{
  ?s ?p ?o .
  ?root rex:root "true"
}
WHERE
{
      { ?root rex:hasNormalizedText "Taliban" }
      UNION
      { ?s rex:hasNormalizedText "Taliban" }
      UNION
      { ?entity rex:hasNormalizedText "Taliban" .
        ?s (owl:sameAs|^owl:sameAs)* ?entity .
      }
      UNION
      {
        ?entity rex:hasNormalizedText "Taliban" .
        ?entity ?pred ?s .
        ?pred rdfs:subPropertyOf* rex:relationship .
      }
      UNION
      {
        ?entity rex:hasNormalizedText "Taliban" .
        ?entity (owl:sameAs|^owl:sameAs)* ?t .
        ?t ?pred ?s .
        ?pred rdfs:subPropertyOf* rex:relationship .
      }
      UNION
      {
        ?entity rex:hasNormalizedText "Taliban" .
        ?entity ?pred ?t .
        ?pred rdfs:subPropertyOf* rex:relationship .
        ?t (owl:sameAs|^owl:sameAs)* ?s .
      }
      ?s ?p ?o .
}
