Returns the tracker:id of the element being notified upon.
Returns the location (e.g. an URI) of the element if the notifier has the flag %TRACKER_NOTIFIER_FLAG_QUERY_LOCATION, and it can be obtained at the time of emission.
Returns the RDF type that this notification event relates to, in their expanded forms (for example, http://www.semanticdesktop.org/ontologies/2007/03/22/nfo#Audio).
A resource may have multiple RDF types. In the case of changes to a resource with multiple types, one event will be notified for each RDF type the notifier is subscribed to.
For performance reasons, Tracker only sends notifications for events that are explicitly marked with the tracker:notify property in their ontology.
Returns the Uniform Resource Name of the element if the notifier has the flag %TRACKER_NOTIFIER_FLAG_QUERY_URN enabled.
This URN is an unique string identifier for the resource being notified upon, typically of the form "urn:uuid:...".
Returns the event type.
