<B>InterfaceB>
o new(Storage=>$storage, Factory => $factory)

Construct the object. $storage is the RDF::Core::Storage object that contains schema data. $factory may specify the RDF::Core::Factory to be used.

o getClasses

Return all classes defined in the model.

o getSubClasses($class, $deep)

Get all subclasses of given $class. $class may be either URI string or RDF::Core::Resource. If $deep is true, inheritance takes a deal.

o getAncestors($class, $deep)

Get all ancestors of a given $class. $class may be either URI string or RDF::Core::Resource. If $deep is true, inheritance takes a deal.

o isSubClassOf($what, $whos)

Tells, whether $what is a subless of $whom. Both of parameters may be either of RDF::Core::Resource or URI string.

o getSubProperties($property, $deep)

Get all subproperties of given $property. $property may be either URI string or RDF::Core::Resource. If $deep is true, inheritance takes a deal.

o getAncestorProperties($property, $deep)

Get all ancestor properties of given $property. $property may be either URI string or RDF::Core::Resource. If $deep is true, inheritance takes a deal.

o isSubClassOf($waht, $whos)

Tells, whether $what is a subless of $whom. Both of parameters may be either of RDF::Core::Resource or URI string.

o getPropertiesOf($class, $deep)

Get all properties of given $class. No inheritance rules are applied, since they are not defined in RDF Schema. $class may be either URI string or RDF::Core::Resource. If $deep is true, inheritance takes a deal.
