* This composite change will create a value partion - see "pattern 2" in * "Representing Specified Values in OWL: "value partitions" and "value sets"" * (http://www.w3.org/TR/swbp-specified-values.) *

* A value partition is an ontology design pattern which is used to represent * a set of closed values for a particular property. For example the property * hasSize might only take values from SmallSize, MediumSize and LargeSize. In * this case, the value partition is Size, and has the values SmallSize, MediumSize * and LargeSize. This composite change will set hasSize to be functional and its * range as Size. Size will be covered by SmallSize, MediumSize and LargeSize and * these classes which represent the values will be made disjoint with eachother. */ public class CreateValuePartition extends AbstractCompositeOntologyChange { private List changes; private final OWLOntology targetOntology; private final Set valuePartionClasses; private final OWLClass valuePartitionClass; private final OWLObjectProperty valuePartitionProperty; /** * Creates a composite change that will create a value partition. * * @param dataFactory A data factory which can be used to create the necessary axioms * @param valuePartitionClass The class which represents the value partition. * @param valuePartionClasses The classes that represent the various values of the value * partition. * @param valuePartitionProperty the property which should be used in conjunction with the * value partition. * @param targetOntology The target ontology which the axioms that are necessary to create * the value partition will be added to. */ public CreateValuePartition(OWLDataFactory dataFactory, OWLClass valuePartitionClass, Set valuePartionClasses, OWLObjectProperty valuePartitionProperty, OWLOntology targetOntology) { super(dataFactory); this.targetOntology = targetOntology; this.valuePartionClasses = valuePartionClasses; this.valuePartitionClass = valuePartitionClass; this.valuePartitionProperty = valuePartitionProperty; generateChanges(); } private void generateChanges() { changes = new ArrayList(); // To create a value partition from a set of classes which represent the values, // a value partition class, a property we... // 1) Make the classes which represent the values, subclasses of the value partition class for (OWLClassExpression valuePartitionValue : valuePartionClasses) { changes.add(new AddAxiom(targetOntology, getDataFactory().getOWLSubClassOfAxiom(valuePartitionValue, valuePartitionClass))); } // 2) Make the values disjoint changes.add(new AddAxiom(targetOntology, getDataFactory().getOWLDisjointClassesAxiom(valuePartionClasses))); // 3) Add a covering axiom to the value partition OWLClassExpression union = getDataFactory().getOWLObjectUnionOf(valuePartionClasses); changes.add(new AddAxiom(targetOntology, getDataFactory().getOWLSubClassOfAxiom(valuePartitionClass, union))); // 4) Make the property functional changes.add(new AddAxiom(targetOntology, getDataFactory().getOWLFunctionalObjectPropertyAxiom(valuePartitionProperty))); // 5) Set the range of the property to be the value partition changes.add(new AddAxiom(targetOntology, getDataFactory().getOWLObjectPropertyRangeAxiom(valuePartitionProperty, valuePartitionClass))); } @Override public List getChanges() { return changes; } }
