#Klasse zum Taggen und Anzeigen der Tags von Projekte bzw. allgemein Webseiten des Institutes
#Tags werden in der Instanz abgespeichert
#Personenname kommen aus dem Virtuoso-Triplestore , lokal erzeugte zusaetliche Name werden dort abgespeichert
#Fuer die Suche ueber die Personenname wird das MetaDataManagerRestlet benoetigt.
#TODO: Zur Zeit werden die entsprechenden Server URLs hier in der Klasse definiert.


# TODO: generell verwaltung der tags im triple store und nicht in zope.
# TODO: mache server und namespaces konfigurierbar im project
