OpenNumisma: A Software Platform For Managing Digital Heritage Numismatic Collections With a Particular Focus on Reflectance Transformation Imaging.
The proposed poster presents digital heritage research related to OpenNumisma; an open source web-based platform focused on digital heritage numismatic collections. The project provides an innovative merge of digital imaging and data management systems that offer great new opportunities for research and the dissemination of knowledge. A key feature of this platform is the application of Reflectance Transformation Imaging (RTI), a computational photographic method that offers tremendous image analysis possibilities for numismatic research. OpenNumisma data can produce Linked Data; the RDF produces a SPARQL endpoint using PHP,ARC2 libraries and is based on CIDOC-CRM Conceptual Reference Model ontology of exchange heterogeneous cultural heritage information.
RTI is a computational photographic method that digitally captures color and surface texture data to produce a dynamic file that allows the user to virtually illuminate, in high analysis, every detail of the photographed object. Furthermore, the enhancing functions of RTI can reveal hidden surface details that are not disclosed under direct empirical examination.
The poster will explicate the platforms’ capabilities in the digitally interactive exploration of coins’ collections, discover embossed inscriptions set in the context of a comprehensive digital library that is designed to disseminate knowledge on the history and culture of ancient and medieval. Designed to be used by non-technical or IT experts, OpenNumisma interactive functions and applications are based on a friendly user interface. The first successful implementation of OpenNomisma in the online coinage collection of the Bank of Cyprus Cultural Foundation.
