Overview

Entity Facts is a data service provided by the German National Library that provides machine-readable “fact sheets” on entities in the Integrated Authority File (GND).

This service makes it possible to use information from the GND with no prior knowledge of bibliographic data formats or cataloguing conventions.

The data is delivered in JavaScript Object Notation (JSON) format. It is optimised for direct display or indexing in other applications. The data can currently only be queried by using GND identifiers. Other search options are facilitated by integration into the German National Library’s data interfaces.

Entity Facts is offered as part of our Linked Data Service. The most commonly used JSON is the variant "JSON for Linking Data" (JSON-LD). This facilitates the processing of data in the triple structure of the Resource Description Framework (RDF).

Entity Facts currently supports the entity types "Person" (example), „Family“ (example), "Corporate Body" (example), "Geographical Entity" (example) and "Event" (example) .

Along with data from the GND, links are furnished to other data providers such as VIAF, ISNI, BNF, LoC, Wikipedia, Wikidata, Wikimedia Commons, Bayerisches Musiker-Lexikon Online, IMDb. The links are taken from publicly available external data such as VIAF and Wikidata or in the form of BEACON files.

Entity Facts was set up in 2014 as part of a project aimed at depicting the entity type “Person”.
