Linked Open Data

Linked Open Data refers to openly and freely available data online, identified via Uniform Resource Identifier (URI) and accessible via HTTP. This allows to link and send requests to various data resources.

The Linked Open Data Set of the ONB Labs includes metadata of our historical newspapers, our historical postcards and the catalogue of the Austrian National Library.

The download of our historical postcards (AKON) per dataset can be retrieved under

http://data.onb.ac.at/AKON/{akon-id}.rdf

For our historical newspapers the link is

http://data.onb.ac.at/ANNO/{anno-id}.rdf.

The primary format used for our historical newspapers and postcards is the Europeana Data Model (EDM). A detailed description of the identifiers can be found under: https://iiif.onb.ac.at/api.

Catalogue data can be retrieved in

• BIBFRAME via https://open-na.hosted.exlibrisgroup.com/alma/{institution-code}/bf/entity/instance/{mms-id},

• JSON-LD via https://open-na.hosted.exlibrisgroup.com/alma/{institution-code}/bibs/{mms-id} or

• RDA/RDF via https://open-na.hosted.exlibrisgroup.com/alma/{institution-code}/rda/entity/manifestation/{mms-id}.rdf.

The institution-code for an MMS-ID from the Network Zone is 43ACC_NETWORK, for a local one 43ACC_ONB. Additional is provided in the Ex Libris Developer Network.

The metadata of over 1,380,000 newspaper issues and 42,800 periodicals is accessible via SPARQL endpoint, as download per dataset or as data dump. The same accounts for the over 38,800 historical postcards (AKON)

A description of the relevant attributes of the EDM-schemata can be found at our SPARQL-LAB.
