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 Nomisma.org. 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.

Nomisma.org 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., http://nomisma.org/pelagios-objects.void.rdf). 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 Nomisma.org'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 http://nomisma.org/id/commodus 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 Nomisma.org SPARQL endpoint. See http://coinhoards.org/id/igch1399 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.

Excavation coins from Priene available in OCRE

The Berlin Münzkabinett is setting up a new database for coin finds from German excavations of Priene:

This database includes the coins of the excavations since 1998 (Museum Balat) and the old excavations of the Berlin Museums (Münzkabinett, Staatliche Museen zu Berlin). By Bernhard Weisser and Johannes Eberhardt (Staatliche Museen zu Berlin) in cooperation with the German Archaeological Institute and the universities in Frankfurt (Wulf Raeck, Axel Filges), Bonn (Frank Rumscheid) and Bursa (Hakan Mert). IT: Jürgen Freundel, Editor: Karsten Dahmen.

So far there are two coins connected to currently published RIC types in OCRE (as a proof of concept), but more coins will be published eventually. The associated types are:

Since the two coins connected to these types have findspots, Priene will appear as a findspot on the map in OCRE. Additionally, with the more advanced mapping features recently introduced on Nomisma.org, the Priene findspot will appear on any map associated with any individual skos:Concepts connected to these coin types, e.g., Claudius Gothicus (http://nomisma.org/id/claudius_ii_gothicus), whose map shows a findspot for Priene and two hoards in Britain--Normanby and Oliver's Orchard Hoards--connected to coins from the University of Virginia.

Nomisma's new interface upgrades will be discussed in further detail in another blog post.

OCRE at the AIA/SCS in San Francisco

Andrew Meadows, one of the project managers for the Online Coins of the Roman Empire project, was in San Francisco today to present on a panel of NEH-funded projects in the archaeological realm, as part of the larger AIA/SCS conference. It generated a string of tweets (and replies) from Eric Kansa of OpenContext, which you can read at https://twitter.com/search?f=tweets&vertical=default&q=%23aiascs%20%40menetys&src=typd. Andy's presentation is more or less represented on Google Docs: https://docs.google.com/document/d/1QXSeOSNnV6-Zxe3dU_desqouTDcIEPIcT_XySZ8gMiA/edit. The presentation is effectively a summary of the state of the digital world of numismatics, including involvement in Pelagios and a crowdsourced coin identification project with MicroPasts to facilitate future integration of Portable Antiquities Scheme coins into OCRE.

The American Numismatic Society Announces the Launch of PELLA

The American Numismatic Society (ANS) is excited to announce the launch of its latest digital platform, PELLA (numismatics.org/pella/), an important new research tool for ancient Greek numismatics that provides a comprehensive, easily accessible online catalogue of the coinage produced by the kings of the Macedonian Argead dynasty (c.700–310 BC). Cataloguing the individual coin types of the kings from Alexander I (ruled 498–454 BC), the first of the Macedonian kings to strike coins, down to Philip III Arrhidaeus (ruled 323–317 BC), PELLA allows users to conduct research on specific types, view examples from multiple collections, conduct statistical analyses of weight and other measurement data, and see maps of where the type was minted and where examples have been found in hoards.

As a linked data project, PELLA connects to the relevant pages within the ANS's collection website, MANTIS (numismatics.org/search/), as well as Inventory of Greek Coin Hoards Online (coinhoards.org), and incorporates material from other public collections. The current version of PELLA provides links to examples of the coinage (in the name) of Alexander the Great and Philip III Arrhidaeus present in the ANS collection, the Münzkabinett of the State Museums of Berlin, and the British Museum totaling nearly 10,000 examples of individual coins. The current version of PELLA uses the numbering system and typology originally created and published by Martin Price in The Coinage in the Name of Alexander the Great and Philip Arhidaeus, London 1991, with the addition of modifications that greatly enhance the volume’s usefulness as an online resource.

PELLA is made possible by stable numismatic identifiers and linked open data methodologies established by the Nomisma.org project. Coin type data are made available with an Open Database License.

Dr. Peter van Alfen, Margaret Thompson Associate Curator of Greek Coins, commented on the announcement. "The Macedonian kings of the Argead dynasty struck arguably the most influential coinages of the ancient Greek world, so it’s appropriate that our first digital project in Greek numismatics focuses on their coinage. We also wanted to provide a specific platform for facilitating research on their coinages, particularly since the ANS holds one of the largest and most important collections of Argead coinage in the world. By being able to link to other important collections, the research potential is significantly enhanced. The ANS is committed to enhancing its online presence and digitizing its collection - PELLA is another example of our progress, and we are proud it well help educate those with general numismatic interest as well as academic researchers.”
