Re: [Virtuoso-users] Inference in Virtuoso 5.07 Sparql DAV Web Service?

[S. Matovic]

Hello Ivan,

thanks for your answer.

I managed to get rdfs:subPropertyOf to work via a rdfs_sule_set but 
rdfs:subClasOf doesnt do.

I used the conductor to create a folder and import this dataset:

<rdf:RDF
    xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#";
    xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#";> 

  <rdfs:Class rdf:about="http://localhost/values#Value0";>
  </rdfs:Class>

  <rdfs:Class rdf:about="http://localhost/values#Value1";>
    <rdfs:subClassOf rdf:resource="http://localhost/values#Value0"/>
  </rdfs:Class>

  <rdfs:Class rdf:about="http://localhost/values#Value2";>
    <rdfs:subClassOf rdf:resource="http://localhost/values#Value1"/>
  </rdfs:Class>

  <rdfs:Class rdf:about="http://localhost/values#Value3";>
    <rdfs:subClassOf rdf:resource="http://localhost/values#Value2"/>
  </rdfs:Class>

  <rdfs:Class rdf:about="http://localhost/values#Value4";>
    <rdfs:subClassOf rdf:resource="http://localhost/values#Value3"/>
  </rdfs:Class>

  <rdfs:Class rdf:about="http://localhost/values#Value5";>
    <rdfs:subClassOf rdf:resource="http://localhost/values#Value4"/>
  </rdfs:Class>

</rdf:RDF>

Than the interactive sql console:

rdfs_rule_set ('test, 'http://localhost:8890/DAV/test');

sparql define input:inference "test" 
PREFIX  rdfs: <http://www.w3.org/2000/01/rdf-schema#>
SELECT * FROM <http://localhost:8890/DAV/test> WHERE {?s rdfs:subClassOf 
<http://localhost/values#Value0>}


Result is only  http://localhost/values#Value1 instead of Value1-5.


Any hint what i did wrong?

Best Regards,
Srdja Matovic
