Monday, April 18, 2016 Is Now a Functioning Pelagios Commons Hub

Given the interest of our partners (like Berlin and the Prehistory Museum of Valencia) in participating in the Pelagios Project, while perhaps lacking the funding to develop export scripts directly, I have extended the functionality of Nomisma to support exporting directly into the Pelagios Open Annotation RDF model. This was a fairly straightforward task which required two new XML pipelines in the Page Flow Controller in Orbeon: one for the VoID metadata RDF and one for the data dump (or dumps, since each dump is chunked into 5,000 coins).

The pipelines execute SPARQL queries that are piped through XSLT transformations into RDF. The VoID RDF aggregates subsets bound to the void:Datasets described in the Nomisma triplestore in order to provide descriptive metadata and license URLs for our partners (e.g., The data dumps execute a SPARQL query that generates a list of nmo:NumismaticObjects linked to mints implicitly by coin types (nmo:hasTypeSeriesItem). Since ancient mints defined on Nomisma are linked to URIs in the Pleiades Gazetteer of Ancient Places, it is fairly simple to make ancient coins that have been ingested into the Nomisma triplestore available in Pelagios.

I also updated the Pelagios icon on the front page of Nomisma.

Lliria Hoard coins join OCRE

Nearly 6,000 Roman Imperial coins of the Lliria Hoard dating from Augustus to Commodus have been imported into's endpoint and are available for geographic and quantitative analysis in OCRE. The coins of this hoard are now housed in two museums: the Prehistory Museum of Valencia and the Archaeological Museum of Lliria. All of the coins have been weighed and photographed, and since they each have attested findspots, they may be used to enhance the geographic visualization of the coin types from the hoard and the characteristics associated with these types (e.g., denominations or rulers). See for example. The Prehistory Museum of Valencia is our first Spanish partner.
