W3C's Ontology Language (OWL)
Defines the basic concepts (resources) of a domain in terms
of
classes
:
classes can be viewed as "sets" of possible individuals
hierarchies of concepts can be defined as
subclasses
Properties are defined by:
constraints on their range and domain, or
specialization (
sub-properties
)
The structure is based on RDF
