Antike Fundmünzen in Europa (AFE) in OCRE

More than 800 coins from Antike Fundmünzen in Europa (AFE), a Römisch-Germanische Kommission (RGK) (a Nomisma partner), have been ingested into the Nomisma triplestore. Of these, only a few dozen are directly linked to URIs in OCRE, but the remaining coins are still available for query by means of directly affiliated triples (such as this SPARQL query below, which gathers a UNION of coins with Vespasian explicitly designated as authority and those that are implied by means of a linked coin type).

SELECT ?object ?type ?weight ?diameter WHERE {
  { ?object nmo:hasAuthority nm:vespasian ; a nmo:NumismaticObject }
  UNION { ?type nmo:hasAuthority nm:vespasian ; a nmo:TypeSeriesItem .
         ?object nmo:hasTypeSeriesItem ?type }
  OPTIONAL {?object nmo:hasWeight ?weight}
  OPTIONAL {?object nmo:hasDiameter ?diameter}
}

These are the first archaeological materials ingested in Nomisma, each with findspots.

See http://numismatics.org/ocre/id/ric.2_1(2).ves.520, for example, of a Vespasianic coin type with a findspot and measurements from the AFE database.

Berlin coins updated in OCRE and CRRO

The Berlin LIDO/XML export data for Roman Imperial Coinage references has been reprocessed, and coins from the Münzkabinett from Valerian through Quintillus are now available in OCRE. The number of imperial coins from Berlin grew about 150 to 3,749. Additionally, the RRC export was reprocessed into RDF following the new Nomisma ontology, and the total number of Republican coins from Berlin available in CRRO has grown to 1,080. The ANS coins for RIC V were updated yesterday, and the University of Virginia coins just before that. I expect to update the RIC V coins from the British Museum in the near future. This will add over 2,000 more coins to OCRE.

Presently, nearly 35,000 coins from the ANS, British Museum, Berlin, and the University of Virginia are available in OCRE. I expect the first batch of archaeological materials from Antike Fundmünzen in Europa (AFE) to be ingested into the Nomisma triplestore soon. This is a tremendous milestone.

All RIC types through Quintillus published in OCRE

Last week, we published all of the types from Valerian and Gallienus in OCRE. A few days ago, we added Claudius Gothicus and Quintillus. There is a subtle difference between the types from the reigns of Valerian and Gallienus and the emperors after 268 in our RIC V workflow. Due to the tremendous number of subtypes from Valerian and Gallienus (and subtypes of these subtypes, when considering every permutation of obverse portrait and mint mark), we decided we needed to speed up the publication process. Beginning with Claudius Gothicus, only the parent type numbers will be published to OCRE so that we will complete RIC Volume X by the close of the NEH grant two years from now. If/when we have the time, we will return to RIC V to fill in the missing subtypes.

Capturing the parent types is of the utmost importance, since most museum and archaeological databases will likely have designated their coins as a parent type, e.g. Gallienus 210, and not Gallienus 210k or Gallienus 210k Subtype 1. The ANS has gone into this level of granularity with respect to linking coins to OCRE subtypes (as have I with linking the University of Virginia collection), but it is doubtful anyone else has. Indeed, at first glance, neither Berlin nor the British Museum link to the subtypes, many of which were not distinctly numbered within RIC. [As an aside, Mantis and UVa have been updated to link to OCRE, but BM and Berlin coins are not yet available.]

However, in order to support the traversal from parent types to subtypes, I have made some enhancements to the OCRE UI (which are not inherent to Numishare). It is possible to link directly to Gallienus 210 and have those coins show up under "Examples of this Type" in the parent record page, but coins linked more granularly to subtypes will also show up under the "Subtypes" section underneath. Click on the Gallienus 210, 210k, and 210k.1 above for an example. What this means is that an archaeological database can link to the parent type when the legend or mint marks are not legible enough for precise identification, but the numismatic data and images can still be made available through OCRE.

In semantic web terms, subtypes are linked to parent types via the skos:broader property. SPARQL queries have been updated throughout Numishare to infinitely gather subtypes with the skos:broader+ modifier, which is enabled by default in the current version of Fuseki we employ as the Nomisma.org SPARQL endpoint (http://bit.ly/1N2pe81).
