Tutorial held at the Semantic Web in Libraries conference in Hamburg, Germany, at November 25th 2013. The tutorial was held together with Kai Eckert, who did Part 1.
When metadata is distributed, combined, and enriched as Linked Data, the tracking of its provenance becomes a hard issue. Using data encumbered with licenses that require attribution of authorship may eventually become impracticable as more and more data sets are aggregated - one of the main motivations for the call to open data under permissive licenses like CC0. Nonetheless, there are important scenarios where keeping track of provenance information becomes a necessity. A typical example is the enrichment of existing data with automatically obtained data, for instance as a result of automatic indexing. Ideally, the origins, conditions, rules and other means of production of every statement are known and can be used to put it into the right context.
Part 1 - Metadata Provenance in RDF: In RDF, the mere representation of provenance - i.e., statements about statements - is challenging. We explore the possibilities, from the unloved reification and other proposed alternative Linked Data practices through to named graphs and recent developments regarding the upcoming next version of RDF.
Part 2 - Interoperable Metadata Provenance: As with metadata itself, common vocabularies and data models are needed to express basic provenance information in an interoperable fashion. We investigate the PROV model that is currently developed by the W3C Provenance Working Group and compare it to Dublin Core as a representative of a flat, descriptive metadata schema.
We actively encourage participants to present their own use cases and open challenges at this workshop. Please contact the organizers for details.
Prior experience: The workshop is intended for participants who have mastered the basics of linked data and want to delve into expressing provenance. Beside a basic understanding of RDF, the linked data principles and the use of ontologies (like Dublin Core or Bibo) to express bibliographic metadata no specialised knowledge is required.
