Ontology linking classes for online store

Question

I'm trying to create ontology for store with Protege 4.3. Everything goes well, but I stuck on something.

I have two classes - Products and Stores. Currently they have object property hasProduct, which has domain Stores and range Products. Let's say that store "Tempo Sport Shop" hasProduct "Brown slippers". But there is a store named "Sport Depot" which has the same product but with different price.

I'm curious how can I put a different price for this product in different stores? I want those Brown Slippers to be 33.00$ in Sport Depot and the exactly same product to cost 41.00$ in Tempo Sport Shop.

Here's the ontology:

<http://www.semanticweb.org/yuriy/ontologies/2014/0/untitled-ontology-23> rdf:type owl:Ontology .


:hasBrand rdf:type owl:ObjectProperty ;

 rdfs:range :Brands ;

 rdfs:domain :Products .


:hasProduct rdf:type owl:ObjectProperty ;

  rdfs:range :Products ;

  rdfs:domain :Stores .

:Brands rdf:type owl:Class .

:Products rdf:type owl:Class .

:Stores rdf:type owl:Class .


:Adidas rdf:type :Brands ,
  owl:NamedIndividual .

:Fluffy_Slippers rdf:type :Products ,
  owl:NamedIndividual ;

  :hasBrand :Nike .

:Nike rdf:type :Brands ,
  owl:NamedIndividual .

:Sport_Depot rdf:type :Stores ,
  owl:NamedIndividual ;

  :hasProduct :Fluffy_Slippers .

:Tempo_Sport rdf:type :Stores ,
  owl:NamedIndividual ;

  :hasProduct :Fluffy_Slippers .

Answer 1

I'd do something like:

:Sport_Depot :sells [ :product :Fluffy_Slippers; 
                      :price "33.00"; 
                      :price_unit "USD" ].
