Detailed Description

Provides convenience methods to handle RDFS data.

Interface based on Sesame's RdfSchemaSource. (Copyright (C) 2002-2006 Aduna BV, GNU LGPL License applies.)

Warning:
Backward inferencing has not been implemented yet. Thus, methods like subClassOf() return the same as directSubClassOf().

Member Function Documentation

Get all defined RDF/S classes.

Returns:
a StatementIterator that iterates over all statements in the model defining an RDF/S class.
StatementIterator Soprano::RdfSchemaModel::directSubClassOf ( const Node subClass,
const Node superClass = Node() 
) const

Gets all direct subClassOf relations with a specific sub- and/or superclass. A class A is a direct subclass of class B if there is no class C such that A is a subclass of C and C is a subclass of B.

Parameters:
subClassThe subclass of the relations that should be returned, or an empty node if relations with any subclass should be returned.
superClassThe superclass of the relations that should be returned, or an empty node if relations with any superclass should be returned.
Returns:
A StatementIterator containing statements of the form (subClass, rdfs:subClassOf, superClass).
StatementIterator Soprano::RdfSchemaModel::directSubPropertyOf ( const Node subProperty,
const Node superProperty = Node() 
) const

Gets all direct subPropertyOf relations with a specific sub- and/or superproperty. A property A is a direct subproperty of property B if there is no property C such that A is a subproperty of C and C is a subproperty of B.

Parameters:
subPropertyThe subproperty of the relations that should be returned, or an empty node if relations with any subproperty should be returned.
superPropertyThe superproperty of the relations that should be returned, or an empty node if relations with any superproperty should be returned.
Returns:
A StatementIterator containing statements of the form (subProperty, rdfs:subPropertyOf, superProperty).
StatementIterator Soprano::RdfSchemaModel::directType ( const Node someClass,
const Node someType 
) const

Gets all direct type relations with a specific instance and/or class.

Parameters:
someClassThe instance of the relations that should be returned, or an empty node if relations with any instance should be returned.
someTypeThe class of the relations that should be returned, or an empty node if relations with any class should be returned.
Returns:
A StatementIterator containing statements of the form (someClass, rdf:type, someType).
StatementIterator Soprano::RdfSchemaModel::domain ( const Node prop,
const Node domain 
) const

Gets all domain relations with a specific property and/or domain class.

Parameters:
propThe property of the relations that should be returned, or an empty node if relations with any property should be returned.
domainThe domain of the relations that should be returned, or an empty node if relations with any domain should be returned.
Returns:
A StatementIterator containing statements of the form (prop, rdfs:domain, domain).

Gets all defined properties.

Returns:
A StatementIterator containing statements of the form (someProperty, rdf:type, rdf:Property).
StatementIterator Soprano::RdfSchemaModel::range ( const Node prop,
const Node range 
) const

Gets all range relations with a specific property and/or range class.

Parameters:
propThe property of the relations that should be returned, or an empty node if relations with any property should be returned.
rangeThe range of the relations that should be returned, or an empty node if relations with any range should be returned.
Returns:
A StatementIterator containing statements of the form (prop, rdfs:range, range).
StatementIterator Soprano::RdfSchemaModel::subClassOf ( const Node subClass,
const Node superClass = Node() 
) const

Gets all subClassOf relations with a specific sub- and/or superclass. Note that the subClassOf relation is reflexive: a class is implicitly always a subclass of itself.

Do not use this method if the Soprano backend supports inferencing. Use directSubClassOf instead which is much faster.

Parameters:
subClassThe subclass of the relations that should be returned, or an empty node if relations with any subclass should be returned.
superClassThe superclass of the relations that should be returned, or an emtpy node if relations with any superclass should be returned.
Returns:
A StatementIterator containing all valid statements of the form (subClass, rdfs:subClassOf, superClass) including those calculated through direct inferencing.
StatementIterator Soprano::RdfSchemaModel::subPropertyOf ( const Node subProperty,
const Node superProperty = Node() 
) const

Gets all subPropertyOf relations with a specific sub- and/or superproperty. Note that the subPropertyOf relation is reflexive: a property is implicitly always a subproperty of itself.

Do not use this method if the Soprano backend supports inferencing. Use directSubPropertyOf instead which is much faster.

Parameters:
subPropertyThe subproperty of the relations that should be returned, or an empty node if relations with any subproperty should be returned.
superPropertyThe superproperty of the relations that should be returned, or an empty node if relations with any superproperty should be returned.
Returns:
A StatementIterator containing all valid statements of the form (subProperty, rdfs:subPropertyOf, superProperty) including those calculated through direct inferencing.
StatementIterator Soprano::RdfSchemaModel::type ( const Node someClass,
const Node someType 
) const

Gets all type relations with a specific instance and/or class.

Do not use this method if the Soprano backend supports inferencing. Use directType instead which is much faster.

Parameters:
someClassThe instance of the relations that should be returned, or an empty node if relations with any instance should be returned.
someTypeThe class of the relations that should be returned, or an empty node if relations with any class should be returned.
Returns:
A StatementIterator containing all valid statements of the form (someClass, rdf:type, someType) including those calculated through direct inferencing.
bool Soprano::RdfSchemaModel::isClass ( const Node resource) const

Checks whether the supplied resource represents a class.

Parameters:
resourceThe resource to check.
Returns:
true if resource is a class, false otherwise.
bool Soprano::RdfSchemaModel::isProperty ( const Node resource) const

Checks whether the supplied resource represents a property.

Parameters:
resourceThe resource to check.
Returns:
true if resource is a property, false otherwise.
bool Soprano::RdfSchemaModel::isDirectSubClassOf ( const Node subClass,
const Node superClass 
) const

Checks whether one resource is a direct subclass of another.

Parameters:
subClassA class.
superClassA class.
Returns:
true if subClass is a direct subclass of superClass, false otherwise.
bool Soprano::RdfSchemaModel::isDirectSubPropertyOf ( const Node subProperty,
const Node superProperty 
) const

Checks whether one resource is a direct subproperty of another.

Parameters:
subPropertyA property.

bool Soprano::RdfSchemaModel::isDirectType ( const Node someClass,
const Node someType 
) const

Returns:
true if someClass is a direct instance of someType, false otherwise.
bool Soprano::RdfSchemaModel::isSubClassOf ( const Node subClass,
const Node superClass 
) const

Checks whether one resource is a subclass of another.

Do not use this method if the Soprano backend supports inferencing. Use isDirectSubClassOf instead which is much faster.

Returns:
true if subClass is a subclass of superClass, false otherwise.
bool Soprano::RdfSchemaModel::isSubPropertyOf ( const Node subProperty,
const Node superProperty 
) const

bool Soprano::RdfSchemaModel::isType ( const Node someClass,
const Node someType
