The ontology data that you provided is not well formed XML, let alone
RDF/XML. It looks like, however, that you're aiming for something
like:
<rdf:RDF
xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#";
xmlns:owl="http://www.w3.org/2002/07/owl#";
xmlns:xsd="http://www.w3.org/2001/XMLSchema#";
xmlns="http://www.semanticweb.org/darius/ontologies/2013/6/rooms#";
xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#";>
<owl:Ontology
rdf:about="http://www.semanticweb.org/darius/ontologies/2013/6/rooms"/>
<owl:Class
rdf:about="http://www.semanticweb.org/darius/ontologies/2013/6/rooms#Gender"/>
<owl:Class
rdf:about="http://www.semanticweb.org/darius/ontologies/2013/6/rooms#Person"/>
<owl:Class
rdf:about="http://www.semanticweb.org/darius/ontologies/2013/6/rooms#City"/>
<owl:NamedIndividual
rdf:about="http://www.semanticweb.org/darius/ontologies/2013/6/rooms#London";>
<rdf:type
rdf:resource="http://www.semanticweb.org/darius/ontologies/2013/6/rooms#City"/>
<owl:topObjectProperty>
<owl:NamedIndividual
rdf:about="http://www.semanticweb.org/darius/ontologies/2013/6/rooms#Male";>
<rdf:type
rdf:resource="http://www.semanticweb.org/darius/ontologies/2013/6/rooms#Gender"/>
</owl:NamedIndividual>
</owl:topObjectProperty>
</owl:NamedIndividual>
<owl:NamedIndividual
rdf:about="http://www.semanticweb.org/darius/ontologies/2013/6/rooms#Ana";>
<rdf:type
rdf:resource="http://www.semanticweb.org/darius/ontologies/2013/6/rooms#Person"/>
</owl:NamedIndividual>
<owl:NamedIndividual
rdf:about="http://www.semanticweb.org/darius/ontologies/2013/6/rooms#Ivan";>
<rdf:type
rdf:resource="http://www.semanticweb.org/darius/ontologies/2013/6/rooms#Person"/>
<owl:topObjectProperty
rdf:resource="http://www.semanticweb.org/darius/ontologies/2013/6/rooms#Male"/>
</owl:NamedIndividual>
</rdf:RDF>
or, in the more readable Turtle syntax:
@prefix : <http://www.semanticweb.org/darius/ontologies/2013/6/rooms#> .
@prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> .
@prefix owl: <http://www.w3.org/2002/07/owl#> .
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .
@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .
:Gender
a owl:Class .
<http://www.semanticweb.org/darius/ontologies/2013/6/rooms>
a owl:Ontology .
:Male
a :Gender , owl:NamedIndividual .
:London
a owl:NamedIndividual , :City ;
owl:topObjectProperty
:Male .
:Ana a owl:NamedIndividual , :Person .
:Ivan
a owl:NamedIndividual , :Person ;
owl:topObjectProperty
:Male .
:Person
a owl:Class .
:City
a owl:Class .
Given that ontology, you can use a query like this:
prefix rooms: <http://www.semanticweb.org/darius/ontologies/2013/6/rooms#>
prefix owl: <http://www.w3.org/2002/07/owl#>
select ?person ?personProperty ?city ?cityProperty ?gender where {
values (?person ?city) {
(rooms:Ivan rooms:London)
}
?person a rooms:Person ;
?personProperty ?gender .
?gender a rooms:Gender .
?city a rooms:City ;
?cityProperty ?gender .
}
and get results like:
$ arq --data data.rdf --query query.sparql
------------------------------------------------------------------------------------------
| person | personProperty | city | cityProperty
| gender |
==========================================================================================
| rooms:Ivan | owl:topObjectProperty | rooms:London |
owl:topObjectProperty | rooms:Male |
------------------------------------------------------------------------------------------
which looks like it should at least get you started toward what you're
trying to achieve.
