RDF::Core::Schema - The RDF Schema access

require RDF::Core::Schema;

my $schema = new RDF::Core::Schema(); $schema->getClasses;

This module provides the basic interface (OO) for RDF Schema manipulation.

Interface

* 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.

* getClasses

Return all classes defined in the model.

* 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.

* 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.

* isSubClassOf($what, $whos)

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

* 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.

* 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.

* isSubClassOf($waht, $whos)

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

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.
