W3C’s Ontology Language (OWL)
Categorizes the basic concepts in terms of
classes
:
classes can be viewed as “sets” of possible concepts
e.g.,
svgEntity
in our example
hierarchies of concepts can be defined as
sub-classes
Properties are defined by:
constraints on their range and domain, or
specialization (
sub-properties
)
