Hi,
My question partly relates to the Neo4J REST db but I think this is the good place to ask because it has experts of semantic ontologies. I'm using OWLAPI to parse my OWL ontology. API gives me triples and I store their Subject, predicate (relationship), and Object into Neo4J db. All individuals in the ontology are stores with their properties successfully. Everything is OK except the Class in the ontology. The subClassOf properties of a class are not stored in the db. Let's take wine.owl as an example. The class Wine is defined like: <owl:Class rdf:ID="Wine"> <rdfs:subClassOf rdf:resource="&food;PotableLiquid" /> <rdfs:subClassOf> <owl:Restriction> <owl:onProperty rdf:resource="#hasMaker" /> <owl:cardinality rdf:datatype="&xsd;nonNegativeInteger">1</owl:cardinality> </owl:Restriction> </rdfs:subClassOf> <rdfs:subClassOf> <owl:Restriction> <owl:onProperty rdf:resource="#hasMaker" /> <owl:allValuesFrom rdf:resource="#Winery" /> </owl:Restriction> </rdfs:subClassOf> <rdfs:subClassOf> <owl:Restriction> <owl:onProperty rdf:resource="#madeFromGrape" /> <owl:minCardinality rdf:datatype="&xsd;nonNegativeInteger">1</owl:minCardinality> </owl:Restriction> </rdfs:subClassOf> .... </owl:Class> The Class Wine is stored as a node in the graph however all information about subClassOf (hasMaker, madeFromGrape...) are not stored. I know that my code using OWLAPI does not handled this information properly so that they can be stored along with the class Wine. Anybody knows how to use OWLAPI or any API that can parse and handle these information of a class definition and store them into the Neo4J db? I also wonder if individuals in the graph are enough for any processes that inquiry the ontology data like Cypher queries. If they are I don't have to worry about the issue above.
