Class
TrackerNamespaceManager
Description [src]
final class Tracker.NamespaceManager : GObject.Object {
/* No available fields */
}TrackerNamespaceManager object represents a mapping between namespaces and
their shortened prefixes.
This object keeps track of namespaces, and allows you to assign short prefixes for them to avoid frequent use of full namespace IRIs. The syntax used is that of Compact URIs (CURIEs).
Usually you will want to use a namespace manager obtained through
tracker_sparql_connection_get_namespace_manager() from the
TrackerSparqlConnection that manages the RDF data, as that will
contain all prefixes and namespaces that are pre-defined by its ontology.
