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
| ELAG 2019 Lightning Talk | 10 May 20192

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, …
