This rule derives the fact that MyStateStructure has rdf:type of RestrictionOnitems.
With the derivation of this fact, all the predicates of the following rule become true:
(owl:onProperty RestrictionOnitems items) (owl:all ValuesFrom RestrictionOnitemsClothing)
(rdf:type MyStateStructureRestriction Onitems) (items MyStateStructure
MyClothingType) -> (rdf:type MyClothingType Clothing).
According to the data obtained by querying the source ontology instance, the
OWLmt mapping engine executes the conceptual mapping patterns to create the
corresponding instances in the target ontology. The conditions specified for each
conceptual mapping pattern also are applied to ensure the accuracy in the mapping
process. In this step, the instances that do not satisfy a particular condition in the
pattern are discarded.
As an example, when the mapping engine executes the SimilarTo pattern (see Figure
6), the body weight at birth instance is obtained (see Figure 11) as a result of the
query of the source instance. The mapping engine then creates the corresponding
birth weight instance (see Figure 12) in the target ontology.
After the creation of the class instances in the target ontology, the property mapping
patterns are applied to create the object and datatype properties for the instances
in the target ontology. During the mapping of the datatype properties, the value
