ZenodoNormalized subject indexing data of K10plus library union catalogThis dataset contains normalized subject indexing data of K10plus library union catalog. It includes links between bibliographic records in K10plus and concepts (subjects or classes) from controlled vocabularies: kxp-subjects_2022-09-30.tsv.gz: TSV format kxp-subjects_2022-09-30.nt.gz: RDF format (in form of NTriples) vocabularies.json: information about vocabularies K10plus K10plus is a union catalog of German libraries, run by library service centers BSZ and VZG since 2019. The catalog contains bibliographic data of the majority of academic libraries in Germany. Bibliographic records in K10plus are uniquely identified by a PPN identifier. Several APIs exist to retrieve more data for a record via its PPN, e.g. link into K10plus OPAC: https://opac.k10plus.de/PPNSET?PPN={PPN} Retrieve full record in MARC/XML format: https://unapi.k10plus.de/?format=marcxml&id=opac-de-627:ppn:{PPN} Get formatted citation for display: https://ws.gbv.de/suggest/csl2?citationstyle=ieee&language=en&database=opac-de-627&query=pica.ppn=${PPN} APIs to look up more data from a notation or identifier of a vocabulary can be found in https://bartoc.org/. For instance BK class 58.55 can be retrieved via DANTE API: https://api.dante.gbv.de/data?uri=http%3A%2F%2Furi.gbv.de%2Fterminology%2Fbk%2F58.55 See vocabularies.json for mapping of vocabulary symbol to BARTOC URI and additional information.
