Member Function Documentation

QString Nepomuk2::OntologyLoader::findOntologyContext ( const QString &  uri )

slot

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 220 of file ontologyloader.cpp.

void Nepomuk2::OntologyLoader::importOntology ( const QString &  url )

slot

Try to retrieve an ontology from the web.

On success ontologyUpdated will be emitted. If the retrieval failed, ontologyUpdateFailed will be emitted.

Definition at line 226 of file ontologyloader.cpp.

void Nepomuk2::OntologyLoader::ontologyUpdated ( const QString &  uri )

signal

Emitted once an ontology has been updated.

This holds for both locally installed ontology files (which are read automatically) and those retrieved from the web via importOntology

void Nepomuk2::OntologyLoader::ontologyUpdateFailed ( const QString &  uri, const QString &  error  )

signal

Emitted if updating an ontology failed.

This holds for both locally installed ontology files (parsing may fail) and for those imported via importOntology.

void Nepomuk2::OntologyLoader::ontologyUpdateFinished ( bool  changesDone )

signal

Emitted once the update of the ontologies is done.

This signal is emitted whenever the ontologies change and needed updating.

It is emitted once the update of the locally installed ontologies is done or once a remote ontolgoy has been imported. Thus, it is the signal to connect to if one wants to perform some maintenance after an ontology update.

void Nepomuk2::OntologyLoader::updateAllLocalOntologies ( )

slot

Update all installed ontologies, independently of their status.

Definition at line 200 of file ontologyloader.cpp.

void Nepomuk2::OntologyLoader::updateLocalOntologies ( )

slot

Update all installed ontologies that changed since the last update.

Definition at line 190 of file ontologyloader.cpp.
