NUMIDAT

OAI – PMH: UK databases

Build your own collection 15 minute coin repository build • Import data via OAI-PMH into Omeka opensource CMS • Not many coin resource OAI endpoints available

NUDS – Numismatic Database Standard• NUDS is a set of suggested field names for recording numismatic information in a column-oriented database.• It is designed to capture information as it currently exists in databases deployed by museums and collectors in “real world” situations.• It is flexible in that it can represent objects for which only very generic information is known or objects that have been described in detail.• It does not mandate a set of required fields.• Was created at an AHRC workshop here at the British Museum

Innovation  Multi period  Multiple object types  Heavy reliance on public donating their information for research  Integrates social media and 3rd party technology  Multiple extraction methods for integration externally

P. Walton PhD research [AHRC] Key Outcomes • When did Republican coins arrive in Britain – pre or post Conquest? Conclusion being that the overwhelming majority were first century military losses. • Where, when and by whom were Claudian copies used? Conclusion being military use at first but continued use by wider population into 2nd century AD. • Where is ‘C’ mint in the reigns of Carausius and Allectus? Conclusion is we don’t know as coinage circulates far too quickly and widely to use mint marks as a way of locating the mint. • Is 4th century a period of decline in Roman Britain? Can chart shrinkage in coin use inwards throughout 4th century... • Transformed understanding of coin use and loss in the Isle of Wight: located 30 new archaeological ‘sites’ using clusters of coin evidence. • Piercebridge coins: established that looking at the treatment of coinage (cutting, bending, scratching) can provide just as much information about site function (particularly of votive sites) as Reece analysis.
