Nearly 2,000 Roman Imperial coins from the University of Graz integrated into Nomisma

After several weeks of working with Elisabeth Steiner at the University of Graz, a large portion of the collection of Roman coins at the Institute of Ancient History and Classical Antiquities has been integrated into the Nomisma.org SPARQL endpoint and is available in OCRE and CRRO. About 300 Republican coins were initially ingested in October, but the coverage has extended by nearly 2,000 coins from the Imperial period. The collection includes images published according to the IIIF specification, which is rapidly becoming the standard API by which new partners make their images available online. Unlike most Nomisma contributors, where intermediary harvesting scripts transform source XML or CSV into Nomisma-compliant RDF, the University of Graz export is a direct serialization of TEI from their Fedora repository into RDF.

What's especially notable about this collection is that it was a successful demonstration of the new Numishare and Nomisma.org OpenRefine reconciliation APIs for normalizing RIC references to OCRE URIs. The first step was to normalize mints, emperors, and denominations to Nomisma preferred labels, which were then used as additional property search parameters for normalizing the RIC numbers themselves to the relevant OCRE URI.

These new reconciliation APIs are the topic of my CAA presentation and paper in two months in the tools session.
