Method Documentation
| __init__ | ( | self ) |
Default constructor. Creates an empty Ontology.
| __init__ | ( | self, | ||
| QUrl | uri | |||
| ) |
Create the ontology referred to by uri. The result is either a valid ontology which could be loaded from the Nepomuk store or a simple class which only contains the uri.
Be aware that the data is only loaded once read.
Subsequent calls result in a simple hash lookup of cached data.
| __init__ | ( | self, | ||
| Nepomuk.Types.Ontology | a0 | |||
| ) |
Default copy constructor
| [Nepomuk.Types.Class] allClasses | ( | self ) |
All classes defined in this ontology, i.e. its namespace.
| [Property] 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::Types::Property] allProperties | ( | self ) |
| Nepomuk.Types.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 an invalid one if the class could not be found.
| Nepomuk.Types.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 an invalid one if the class could not be found.
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 an invalid one if the property could not be found.
