Detailed Description

Filter model to manage NRL ontologies.

Can be used to manage ontologies stored in a model. The ontologies are stored in NRL graphs.

Constructor & Destructor Documentation

Nepomuk2::OntologyManagerModel::OntologyManagerModel	(	Soprano::Model *	parentModel = `0`,
		QObject *	parent = `0`
	)

Create a new model.

Nepomuk2::OntologyManagerModel::~OntologyManagerModel ( )

Destructor.

Definition at line 242 of file ontologymanagermodel.cpp.

QUrl Nepomuk2::OntologyManagerModel::findOntologyContext ( const QUrl & uri )

Tries to find the ontology uri in the local Nepomuk store.

Returns: The context (named graph) storing the ontology's statements or an invalid URI if the ontology could not be found.

Definition at line 415 of file ontologymanagermodel.cpp.

QDateTime Nepomuk2::OntologyManagerModel::ontoModificationDate ( const QUrl & uri )

Determine the modification time of a stored ontology.

The modification time of an ontology is the time it was stored into the model.

Parameters

uri	The namespace of the ontology.

Returns: The modification time of the ontology identified by uri or an invalid QDateTime if the ontology was not found.

Definition at line 392 of file ontologymanagermodel.cpp.

bool Nepomuk2::OntologyManagerModel::removeOntology ( const QUrl & ns )

Remove an ontology from the model.

Parameters

ns	The namespace of the ontology.

Returns: true if the ontology was found and successfully removed. false in case the ontology was not found or an error occurred.

Definition at line 371 of file ontologymanagermodel.cpp.

bool Nepomuk2::OntologyManagerModel::updateOntology	(	Soprano::StatementIterator	data,
		const QUrl &	ns = `QUrl()`
	)

Update an ontology.

Parameters

data	The actual statements defining the ontology. These statements have to either already define the proper NRL graphs or not define graphs at all. In the latter case the graphs will be created.
ns	The namespace of the ontology. If this is left invalid it will be determined from the data.

Returns: true if the data was valid and the ontology was successfully updated. otherwise.
