Publishing Metadata Provenance
Jana Hentschke | German National Library
2. Our Problem
– Metadata from multiple sources
– Attribution needed - also in data exchange
– Example:
Users of our metadata should be able to recognise if a
GND Subject Heading was assigned to a publication by a
cataloguer or by an automated process

3. Solutions
– MARC Bibliographic has field 883 (… digestible?)
– For RDF data we came up with
- PROV Ontology (PROV-O)
- Design pattern: Qualified Relations
- URIs and descriptions for new entities:
prov:Activity, prov:Plan, prov:SoftwareAgent, …

6. What‘s on offer
– Data dumps at https://data.dnb.de/opendata/
(„dnb-all_ldsprov…“ in .rdf, .ttl, .jsonld, .nt, .hdt)
– Details + schedule at https://wiki.dnb.de/x/46G5C (German)
- Next: Provenance information also on URI resolving of individual entities
– Temporary solution for provenance of outgoing links in GND RDF:
… a table on a wiki page: https://wiki.dnb.de/x/TZa5C
