2.4. Preconstructed Descriptors

To have control over the amount of synchronization that happens between the internal-state of a descriptor and an ontology, a developer can utilize descriptors that implement one or more expressions. OWLOOP API provides some preconstructed descriptors that implement different number of expressions.

In the package owloop/Descriptor/utility:

• classDescriptor/ package contains the following Java-classes:

  • FullClassDesc: an example of a descriptor which implements 6 expressions (i.e., Equivalent, Disjoint, Sub, Super, Instance, Definition).
  • HierarchicalClassDesc: an example of a descriptor which implements 2 expressions (i.e., Sub, Super).
  • InstanceClassDesc: an example of a descriptor which implements 1 expression (i.e., Instance).
  • RestrictionClassDesc: an example of a descriptor which implements 4 expressions (i.e., Instance, Equivalent, Disjoint, EquivalentRestriction).

• dataPropertyDescriptor/ package contains the following Java-classes:

  • FullDataPropertyDesc: an example of a descriptor which implements 6 expressions (i.e., Equivalent, Disjoint, Sub, Super, Domain, Range).
  • DomainRangeDataPropertyDesc: an example of a descriptor which implements 2 expressions (i.e., Domain, Range).
  • HierarchicalDataPropertyDesc: an example of a descriptor which implements 2 expressions (i.e., Sub, Super).
  • RestrictionDataPropertyDesc: an example of a descriptor which implements 2 expressions (i.e., Disjoint, Equivalent).

• individualDescriptor/ package contains the following Java-classes:

  • FullIndividualDesc: an example of a descriptor which implements 5 expressions (i.e., Equivalent, Disjoint, Type, ObjectLink, DataLink).
  • LinkIndividualDesc: an example of a descriptor which implements 2 expressions (i.e., ObjectLink, DataLink).
  • RestrictionIndividualDesc: an example of a descriptor which implements 2 expression (i.e., Disjoint, Equivalent).
  • TypeIndividualDesc: an example of a descriptor which implements 1 expression (i.e., Type).

• objectPropertyDescriptor/ package contains the following Java-classes:

  • FullObjectPropertyDesc: an example of a descriptor which implements 7 expressions (i.e., Equivalent, Disjoint, Sub, Super, Domain, Range, Inverse).
  • DomainRangeObjectPropertyDesc: an example of a descriptor which implements 2 expressions (i.e., Domain, Range).
  • HierarchicalObjectPropertyDesc: an example of a descriptor which implements 2 expressions (i.e., Sub, Super).
  • RestrictionObjectPropertyDesc: an example of a descriptor which implements 3 expressions (i.e., Disjoint, Equivalent, Inverse).
