How to Use RRDP

The browse page in RRDP currently contains a list of all dies published in the project, with minimal facets for filtering the results. This interface will eventually integrate search mechanisms for symbols that appear on the dies, which have not been incorporated into the RRC type descriptions published in Coinage of the Roman Republic Online.

The page for each die will include relevant obverse or reverse images to which the die URI has been assigned, whether extracted from SITNAM or other contributors. These images link to the holding institutions' databases. Additionally, die pages will include a network graph showing the links between the die ID and the obverse or reverse dies that correspond to the ID. The line weight between die nodes in the network graph reflects volume of production, based on the number of specimens presently cataloged with die IDs. Additionally, an HTML table will also depict these die links and numeric counts.

However, the most logical entry point to studying die relationships by type is through CRRO itself. Applicable types in CRRO will display a similar network graph and die relationship table, but reflecting a broader scope than on the level of an individual die URI. From CRRO, it is possible to navigate to each RRDP die page and/or individual specimens. Specimens published in SITNAM also link to one or more dies for the obverse and reverse. This integrated specimen-type-die Linked Open Data infrastructure is flexible enough to accommodate multiple die attestations, i. e., multiple scholars can make different die attributions about the same coin.

Objects published in SITNAM, reflecting Schaefer's archival materials copied primarily from auction and collection catalogs, also link to the source document from whence they were digitally annotated. Therefore, users can view a particular coin within its archival context, adjacent to similar die-linked images within Schaefer's research notebooks.
