Deutsche National Bibliothek

Created on Jan 14th, 2021

The German National Library is Germany's central archival library. It collects, documents and archives all publications and sound recordings issued in Germany since 1913 together with works that were compiled in the German language or relate to Germany. Books, journals, CDs, records, maps, online publications – we collect them all without exception, without bias and in the original. The collection is supplemented by the holdings in the German Music Archive, the German Museum of Books and Writing and the German Exile Archive 1933–1945. Homepage:

The German Union Catalogue of Serials (ZDB) is one of the world's largest databases dedicated to journals, newspapers, serials and other periodically issued publications from all countries, in all languages, with no time restrictions and in printed, electronic or other forms.

The ZDB currently contains over 1.8 million bibliographic records with more than 16.5 million holding records dating from 1500 to the present day. These were compiled in cooperation with around 3,700 German and Austrian libraries.

The Staatsbibliothek zu Berlin – Preußischer Kulturbesitz and the German National Library are responsible for the maintenance and the further development of the ZDB as equal partners.


Die GND-Sachgruppen werden dazu verwendet, einen systematischen Zugang zu Individualnamen und Sachschlagwörtern der Gemeinsamen Normdatei (GND) zu ermöglichen und fachliche oder Ausschnitte oder Teilausgaben zu bilden.

This ontology describes the GND elements, defined as a dictionary of named properties and classes using W3C's RDF technology.

GND stands for “Gemeinsame Normdatei” (Integrated Authority File) and offers a broad range of elements to describe authorities. The GND originates from the German library community and aims to solve the name ambiguity problem in the library world. Corresponding data is usually expressed in a customized MARC 21 Authority Format (GND MARC Format) which is quite domain specific and is not used beyond the library and publisher world. The GND ontology tries to bridge this gap by providing a format specification for the usage in the semantic web.

The need for name disambiguation and entries having an authoritative character is an issue that concerns a lot more communities than the library world. In a growing information society the unique identification and linking of persons, places and other authorities becomes more and more important. The GND Ontology aims to transfer the made experience from libraries to the web community by providing a vocabulary for the description of conferences or events, corporate bodies, places or geographic names, differentiated persons, undifferentiated persons (name of undifferentiated persons), subject headings, and works.

To ensure compatibility, the GND ontology aligns with already established vocabularies such as the FOAF vocabulary as well as with new ones like the RDA Vocabularies. We aim to align a number of additional vocabularies as soon as possible wherefore vocabulary suggestions as well as contribution in the alignment work is more than welcome.

GND Gender is a value vocabulary (skos:ConceptScheme) listing the possible gender values used in the RDF encoding of the information in the Integrated Authority File (Gemeinsame Normdatei, GND).

The DNB RDF Vocabulary is a collection of classes, properties and datatypes used within the DNB's linked data service. It complements the GND Ontology which is specifically geared towards authority data from the Integrated Authority File (GND), whereas this vocabulary is more general-purpose.

The ontology of agent relationships (AgRelOn) defines relations of persons to other persons and to organisations, since agents (persons, organisations) and their interconnections are important in the cultural heritage domain. AgRelOn is developed to foster uniform cataloging as well as semantic searchability of and via relations between agents. Therefore, a general set of nearly 70 relationhip types is provided. AgRelOn discerns private acquaintanceship, group affiliation, correspondence, occupational contact, kinship, spiritual contact, and vital/lethal contact. For these kinds of relations more specific sub-relations are formulated. Meta statements are supported to obtain transparency of reliability and provenance as well as validity period of facts. The modelled relations are determined on the one hand by exemplary knowledge base searches, on the other hand by available data sources. Hence, the model consciously is incomplete and pertinent to a cultural area and period.
