Method Documentation
| __init__ | ( | self ) |
Default constructor. Creates an empty Ontology.
| __init__ | ( | self, | ||
| Nepomuk.Ontology | a0 | |||
| ) |
Default copy constructor
| [const Clas] allClasses | ( | self ) |
All classes defined in this ontology, i.e. its namespace.
| [const Propert] allProperties | ( | self ) |
A list of all properties defined in this ontology. This does not include properties that use classes of this ontology but are defined in a different one.
| Nepomuk.Class findClassByLabel | ( | self, | ||
| QString | label, | |||
| QString | language=QString() | |||
| ) |
Search for a class in the ontology by its label.
- Parameters:
-
label The label of the class (i.e. rdfs:label)
- Parameters:
-
language The language in which the label was specified. If empty the default rdfs:label is returned.
- Returns:
- the Class object identified by label or 0 if the class could not be found.
| Nepomuk.Class findClassByName | ( | self, | ||
| QString | name | |||
| ) |
Search for a class in the ontology by its name.
- Parameters:
-
name The name of the class.
- Returns:
- the Class object identified by name or 0 if the class could not be found.
| Nepomuk.Class findClassByUri | ( | self, | ||
| QUrl | uri | |||
| ) |
Search for a class in the ontology by its name.
- Parameters:
-
uri the URI of the class
- Returns:
- the Class object identified by uri or 0 if the class could not be found.
| Nepomuk.Property findPropertyByLabel | ( | self, | ||
| QString | label, | |||
| QString | language=QString() | |||
| ) |
Search for a property in the ontology by its label.
- Parameters:
-
label The label of the property (i.e. rdfs:label)
- Parameters:
-
language The language in which the label was specified. If empty the default rdfs:label is returned.
- Returns:
- the Property object identified by label or 0 if the property could not be found.
| Nepomuk.Property findPropertyByName | ( | self, | ||
| QString | name | |||
| ) |
Search for a property in the ontology by its name.
- Parameters:
-
name The name of the property.
- Returns:
- the Property object identified by name or 0 if the property could not be found.
| Nepomuk.Property findPropertyByUri | ( | self, | ||
| QUrl | uri | |||
| ) |
Search for a property in the ontology by its name.
- Parameters:
-
uri the URI of the property
- Returns:
- the Property object identified by uri or 0 if the property could not be found.
| Nepomuk.Ontology load | ( | QUrl | uri | |
| ) |
Loads an ontology.
Dependancies are resolved automatically if possible.
- Returns:
- An Ontology object representing the ontology identified by uri or an invalid Ontology object if the resource identified by uri is either not an ontology or does not exist.
| QUrl uri | ( | self ) |
The URI of the ontology, i.e. its namespace
