data-hnm-hu - Hungarian National Museum Datasets

Open linked data from the Hungarian National Museum.
The following datasets and subsets are available:

• Collections (dataset, short name: colls)
• Bibliographic Data of the Central Library (subset, short name: colls-lib-bib)

The Bibliographic Data of the Central Library contains the entire online catalogue of the library in BIBFRAME format and provides links to external sources including: BNF, ISNI, LC NAF, VIAF and Wikidata.

One of the aims of this publication is to make Hungarian librarians more familiar with BIBFRAME. In order to achieve this the BIBFRAME and the MARC descriptions are cross linked. Knowing the BIBFRAME URI of an instance:

http://data.hnm.hu/id/colls/lib/bib/Instance/MNMKVT19563

one can get the MARC description by appending ".opac" to the URI:

http://data.hnm.hu/doc/colls/lib/bib/Instance/MNMKVT19563.opac.

Knowing the permalink of an OPAC record

http://link.hnm.hu/lib/bib/MNMKVT19563

one can get the BIBRAME description in HTML format by appending .rdf to it:

http://link.hnm.hu/lib/bib/MNMKVT19563.rdf.

Other formats can also be invoked by appending the following extensions:
.rdf-ttl, .rdf-nt, .rdf-json, .rdf-jsonld, and .rdf-rdf. The .rdf-rdf extentsion gives back the rdf-xml format.

Clicking the BIBFRAME icon in the OPAC also leads to the BIBFRAME description.

The OPAC pages also support the link rel discovery service in order for the crawlers and other programs to find the RDF descriptions in different formats automatically.

The project was carried out in partnership with @Cult srl., Italy (MARC BIBFRAME conversion) and Monguz Ltd., Hungary (OPAC modification). We also used some parts of the ALIADA open source tool.

The @Cult MARC21 BIBFRAME conversion have the following main features:

• Work recognition
• Entity recognition
• Name entities are linked to external datasets.

The BIBFRAME dataset will be updated periodically as BIBFRAME and the conversion evolves.
