So what is OWL-DL and OWL-Lite?
(cont.)
-
This explains the restrictions in using OWL predicates and
classes:
-
- strict separation of owl:Thing and owl:Class
(corresponding to individuals and classes in Description
Logic)
- restricted usage of rdf:type, rdf:subClassOf,
etc, predicates (they do not
correspond to general
roles in Description Logic)
- separation of object properties (corresponding to roles) and
datatype properties
-
It also shows the origin of some of the OWL constructions (eg,
creating a class via property restrictions)
