[Rdfapi-php-interest] [ask-help] query sparql

[Dwi M. <edu...@gm...>]

 Hello All,

I have ontology like this (generate using Protégé :-D):

    <owl:Class rdf:about="#Documentation_Project">
        <owl:equivalentClass>
            <owl:Class>
                <owl:intersectionOf rdf:parseType="Collection">
                    <rdf:Description rdf:about="#Project"/>
                    <owl:Restriction>
                        <owl:onProperty rdf:resource="#produces"/>
                        <owl:allValuesFrom rdf:resource="#Authoring"/>
                    </owl:Restriction>
                </owl:intersectionOf>
            </owl:Class>
        </owl:equivalentClass>
        <owl:disjointWith rdf:resource="#Implementation_Project"/>
    </owl:Class>

I try to serialize it using RDF API PHP the result is below:

<owl:Class rdf:ID="Documentation_Project"/>
<owl:Class rdf:nodeID="bNode11"/>

<rdf:Description rdf:ID="Documentation_Project">
   <owl:equivalentClass rdf:nodeID="bNode11"/>
</rdf:Description>

<rdf:Description rdf:nodeID="bNode11">
   <owl:intersectionOf rdf:nodeID="bNode12"/>
</rdf:Description>

<owl:onProperty rdf:ID="produces"/>
<owl:allValuesFrom rdf:ID="Authoring"/>

<rdf:Description rdf:nodeID="">
   <rdf:first rdf:resource="#produces"/>
   <rdf:rest rdf:nodeID="bNode13"/>
</rdf:Description>

<rdf:Description rdf:nodeID="bNode13">
   <rdf:first rdf:resource="#Authoring"/>
   <rdf:rest rdf:resource="http://www.w3.org/1999/02/22-rdf-syntax-ns#nil"/>
</rdf:Description>

<rdf:Description rdf:nodeID="bNode12">
   <rdf:first rdf:resource="#Project"/>
   <rdf:rest rdf:resource="http://www.w3.org/1999/02/22-rdf-syntax-ns#nil"/>
</rdf:Description>


That ontology has restriction:  Implementation_Project _=_  Project AND 
produces ONLY Authoring

The Questions:
1. How to query the restriction above using Sparql?
    I mean the query result return the collection of Implementation_Project
 
                I try :
                        SELECT ?o ?x
                        WHERE {
                                    
<http://www.example.com/ontology/thesis.owl#Documentation_Project> 
<http://www.w3.org/2002/07/owl#equivalentClass> ?o
                                    ?o 
<http://www.w3.org/2002/07/owl#intersectionOf> (?x)
                           }";

                I got the Project only. Where is produces, allValueFrom 
and Authoring?


Could you help this?

Thank you.
