OWLAPI find all DataSomeValuesFrom of a specific class
1
This is a part of my OWL File:
# Class: :Book (:Book)
SubClassOf(:Book ObjectSomeValuesFrom(:writtenBy owl:Thing))
SubClassOf(:Book DataSomeValuesFrom(:genre rdfs:Literal))
SubClassOf(:Book DataSomeValuesFrom(:title rdfs:Literal))
How can i get only the DataSomeValuesFrom attributes?
i'm using owlapi 5.1.0
and Hermit as reasoner.
EDIT: This is how i solved. I don't know if this is the right method but it works.
Thanks to @AKSV for answer me with very useful information....
for (OWLClass cls : o.getClassesInSignature()){
Set<OWLSubClassOfAxiom> set = o.getSubClassAxiomsForSubClass(cls);
for(OWLSubClassOfAxiom subcl : set){
OWLClassExpression nomeattribEXPR = subcl.getSuperClass();
if(nomeattribEXPR.getClassExpressionType().toString().equals("DataSomeValuesFrom")){
//do something
}
}
}
}

aha, and where is the code you tried so far? load the ontology, get all subclass axioms, and then check for those with superclass being of typeOWLDataSomeValuesFrom

I don't understand the "aha". Anyway i posted the question because i don't know how to use very well OWLAPI and all i ask is a short snippet with a short explanation.

Your solution works indeed. A minor improvement, you can use a "better" comparison of the class expression type by using the enum, i.e.nomeattribEXPR.getClassExpressionType() == ClassExpressionType.DATA_SOME_VALUES_FROM

Use a visitor for best effect (no need to check strings for types):
// this is OWLAPI 5; for OWLAPI 4, use OWLObjectVisitorAdapter
OWLObjectVisitor v=new OWLObjectVisitor(){
public void visit(OWLSubClassOfAxiom ax) {
ax.getSuperClass().accept(this);
}
public void visit(OWLDataSomeValuesFrom c){
//do something
}
};
for (OWLClass cls : o.getClassesInSignature()){
o.getSubClassAxiomsForSubClass(cls).forEach(ax->ax.accept(v));
}
