NAME

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

SYNOPSIS

require RDF::Core::Schema;

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

DESCRIPTION

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.
