ANS coins from RIC 6-10 published to OCRE, and other updates

Following the release of volumes 6, 7, 8, and 10 to OCRE, we have republished our coins from these volumes to link them into the newly-published coin type URIs. This represents an addition of more than 17,000 physical specimens of late Roman coinage into OCRE, including photographs for more than 3,000 of these (and photographic gaps from previous volumes of RIC). There are now 36,000 Roman imperial coins from the ANS collection in OCRE, and 60,000 in total from all our partners. Including CRRO and PELLA, there are just under 100,000 physical coins aggregated by's SPARQL endpoint.

In addition to these coins, the Portable Antiquities Scheme provided access to several hundred imperial coins linked to OCRE URIs. The PAS had previously linked its entire collection of Republican coins (nearly 1,000) into CRRO, but the inclusion of imperial material in OCRE is a watershed moment for the study of Roman numismatics. These are the first few hundred of potentially hundreds of thousands of coins published in their database, each with attested findspots. This will have a dramatic effect on geographic analysis of ancient monetary circulation and trade.

The Harvard Art Museums API was also reprocessed. Harvard's coverage of late Roman coinage is quite good, and their contribution to OCRE has more than doubled to 1,300 coins.

RIC 6, 7, 8, and 10 published to OCRE

After filling in gaps in Nomisma IDs necessary for the publication of RIC 10 (including the extension of Numishare to support the creation and publication of monogram URIs with images), we have pushed RIC 6, 7, 8, and 10 into Online Coins of the Roman Empire (OCRE). The symbol publication extension of OCRE can be seen at Currently, each image is a PNG file, but will be replaced with SVG soon. We have developed a workflow to covert True Type Fonts representing Roman imperial numismatic symbols provided by Slovenian partners to SVG with a combination of the open source Linux tools, FontForge and Inkscape.

These four volumes represent a huge number of types, increases OCRE's types in excess of 13,000 up to a total that now exceeds 38,000. David Wigg-Wolf is working on the RIC 9 spreadsheet, and we hope to publish both that and the remainder of RIC 5 by the end of the year.

The next task for this OCRE update is to process several thousand images through our workflow and publish the coins in the ANS curatorial database that link to OCRE IDs into Mantis so that they will become available in OCRE via the SPARQL endpoint.

Archaeological Museum of Münster University joins Nomisma

Thanks to the outreach conducted by the Berlin Münzkabinett and the reuse of their curatorial database platform, the  Archaeological Museum of Münster University has been integrated into the consortium. There are a little over 40 coins that link to URIs for types published by CRRO, OCRE, and PELLA available so far. Those of you who use the Berlin database will recognize the similarity in the interface. Additionally, like the Berlin collection, the Münster database uses the same export mechanisms. I have updated my PHP scripts for processing Berlin's LIDO exports to make them more generalizable for the entire database framework so that I don't have to maintain multiple scripts for processing minutely different LIDO exports into Nomisma-compliant RDF. The script is available at

You can see an example of one of their coins at RRC 473/1, along with coins from the ANS, Berlin, Portable Antiquities Scheme, and the British Museum.

OCRE now available in Polish

With thanks to Adam Degler, translations for NUDS element names and interface components have been incorporated in Numishare. I re-indexed Online Coins of the Roman Empire into Solr, which has made the search and browse interfaces available in Polish (for facets; type descriptions are still only available in English). The facets are derived from SKOS preferred labels from The Polish coverage of Nomisma IDs relevant to Roman Imperial coins is nearly complete. I also re-indexed Coinage of the Roman Republic Online. The interface is available in Polish as well, but the coverage of Republican entities is not as complete as the Imperial period.

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.

Updating MANTIS and IGCH: Incorporating further context into our collection

For the first time, I am faced with a decision whether to post an update on the Numishare blog or XForms for Archives, my other blog for EADitor, xEAC, ETDPub, and our specific implementations of these frameworks within the American Numismatic Society.

I have been working significantly over the last few weeks in overhauling our infrastructure to interlink our projects more thoroughly. I have posted in the past about publishing our archival authorities and collections into a SPARQL endpoint in order to make these systems more interoperable. I extended this system so that our Digital Library publications would go into this endpoint as well, so that we can make our publications and archival materials available through our EAC-CPF collection (and vice versa). Last week, I re-wrote the TEI->RDF transformation in EADitor (for collections of facsimile images) to conform to the same Open Annotation model that I implemented for TEI EBooks published in the Digital Library.

This opened the door for specific mentions of coins, hoards, and other entities defined by URIs in Edward Newell's research notebooks to be made available in other systems, namely, in IGCH itself and through MANTIS.

For example, IGCH 1508 now contains two annotations for our library or archival materials--from Noe's recently published EBook Numismatic Notes and Monographs 1: Coin Hoards and one of Newell's research notebooks. It is possible to click on a link for any mention of these hoards on any page of the notebook or section of an EBook. Furthermore, IGCH has been extended further to display a list of coin types that appear in a hoard, with examples of coins (from PELLA). It is possible to download either all types or all coins from a hoard from the SPARQL endpoint. See for example.

The same basic code applies in MANTIS. Broadly speaking, Numishare has been updated so that it may read Open Annotations from an optional archival SPARQL endpoint (in this case, the endpoint is for Archer). It will display a link to a page or section that mentions a particular object in the ANS collection.

I will be discussing the integration of these frameworks into a cohesive Library, Archive, and Museum linked data infrastructure at CAA in Oslo in several weeks.
