Improving Data Quality by Rules: A Numismatic Example

The archaeological data dealt with in our database solution Antike Fundmünzen in Europa (AFE), which records finds of ancient coins, is entered by humans. Based on the Linked Open Data (LOD) approach, we link our data to Nomisma.org concepts, as well as to other resources like Online Coins of the Roman Empire (OCRE). Since information such as denomination, material, etc. is recorded for each single coin, this information should be identical for coins of the same type. Unfortunately, this is not always the case, mostly due to human errors. Based on rules that we implemented, we were able to make use of this redundant information in order to detect possible errors within AFE, and were even able to correct errors in Nomimsa.org. However, the approach had the weakness that it was necessary to transform the data into an internal data model. In a second step, we therefore developed our rules within the Linked Open Data world. The rules can now be applied to datasets following the Nomisma. org modelling approach, as we demonstrated with data held by Corpus Nummorum Thracorum (CNT). We believe that the use of methods like this to increase the data quality of individual databases, as well as across different data sources and up to the higher levels of OCRE and Nomisma.org, is mandatory in order to increase trust in them

Digital Humanities Solutions for Pan-European Numismatic and Archaeological Heritage Based on Linked Open Data

This paper discusses current challenges in archaeological cultural heritage data management and presents the interdisciplinary research project DigiNUMA. The project investigates solutions in data harmonisation and dissemination of pan-European cultural heritage through an interdisciplinary and cross-sectoral project in Digital Humanities, semantic computing, participatory heritage, museum collections management and archaeological/numismatic studies. Using Finnish and English numismatic data as a test case, DigiNUMA creates ontological infrastructure and a proof-of-concept data model for finely-grained Linked Open Data (LOD) harmonisation across national and international databases for cultural heritage data, and tests it through a broad suite of Digital Humanities analyses.Peer reviewe

Frankfurt am Main, Deutschland. ClaReNet. Klassifikation und Repräsentation keltischer Münzprägungen im Netz. Das Projekt von 2021 bis 2024

The joint project ClaReNet, funded by the Federal Ministry of Education and Research, is testing the possibilities and the limits of new methods of classification and representation on the basis of three Celtic coinages, each selected as an example for specific research questions and problems. Traditional approaches to classification in numismatics and archaeology are compared with classification methods from information technology, including deep learning. An extendable virtual union catalogue, celticcoinage.org, complying with the FAIR principles, will be implemented for the coin series that we are investigating. The work process will be accompanied by a science and technology study, which will contribute to a reflection on the changes in knowledge processes that result from the use of digital tools and algorithms. The aim is to systematically assess in an interdisciplinary dialogue the potential and limits of automation for processes of classification and representation in numismatics and archaeology

Ding-Editionen. Vom archäologischen (Be-)Fund übers Corpus ins Netz

Corpora, thing-editions, are a central epistemic instrument of knowledge generation for archaeology. Due to digitisation attention has turned once more to various strategies and the politics of representation, and in the course of the debate on (post-)factualism and cultures of knowledge and data we are striving to render the production of knowledge more visible and comprehensible. Following B. Latour’s concept of circulating reference, editions are products of a praxeological connection between the world and representations. This is a report on the ongoing discussion of central questions and objectives for digital corpora and research data management following the FAIR (findable, accessible, inter-operable, re-usable) principle

Münzproduktion und Münzversorgung in den Nordwestprovinzen in der frühen und mittleren Kaiserzeit

Die Regierungszeit des Septimius Severus markierte einen deutlichen Einschnitt in der Versorgung der Nordwestprovinzen mit Münzen. Der Zufluss an Bronzegeld hörte so gut wie auf und ab dem Ende des 2. Jahrhunderts gelangte in die britannischen, germanischen und nordgallischen Provinzen fast ausschließlich Silber. Gleichzeitig ging der Zufluss an römischen Silbermünzen in das nordeuropäische Barbaricum stark zurück. Früher wurde diese Unterbrechung mit der Verringerung des Feingehalts der Denare in Verbindung gebracht, heute sieht die Forschung eher eine bewusste politische Entscheidung, die Zahlung von Subsidien u. Ä. an die Germanen einzustellen.Was waren die Gründe für diese Veränderungen? Mussten die Zahlung an die Germanen eingestellt werden, weil das Silber knapp und innerhalb des Reichs benötigt wurde? Der Druck auf die kaiserlichen Finanzen muss enorm gewesen sein: Unter Septimius Severus wurde der Militärsold verdoppelt.The reign of Septimius Severus saw a dramatic change in the supply of fresh coins to the north-west provinces. The flow of bronze to the area virtually ceased and from the end of the 2nd century the British, German and Gallic provinces were supplied almost exclusively with silver. At the same time the flow of silver to the North European Barbaricum was abruptly reduced. Previously this caesura was attributed to the reduction in the fineness of the denarius, however, today it is generally regarded as the result of a conscious political decision to stop the payment of subsidies, etc. to the Germani.What were the reasons behind this change? Were the payments to the Germani stopped because there was a shortage of silver and it was more urgently needed within the Empire? There must have been enormous pressure on the imperial finances: Severus doubled military pay.El mandato de Septimio Severo marcó un claro recorte en el abastecimiento de monedas a las provincias noroccidentales. El flujo de dinero de bronce cesó prácticamente y a partir de finales del siglo II a las provincias británicas, germánicas y del norte de la Galia llegó casi exclusivamente plata. Al mismo tiempo, el flujo de monedas romanas de plata en el Barbaricum noreuropeo disminuyó drásticamente. En el pasado, esta interrupción se asociaba con una reducción de la pureza de los denarios; sin embargo, en la actualidad, la investigación revela más bien una decisión política deliberada para dejar de pagar subsidios y similares a los germanos. ¿Cuáles fueron las razones de estos cambios? ¿Hubo que dejar de pagar a los germanos porque la plata escaseaba y se necesitaba en el Imperio? La presión sobre las finanzas imperiales tuvo que ser enorme: Severo duplicó el salario militar

Forschungsvorhaben MGA: Münze und Gesellschaft in Alteuropa

MGA considers numismatic material as evidence for social, political, economic and cultural developments in an area stretching from Britain to the Black Sea. The basis is the collection and documentation of coin finds from the study area in the database AFE, which has been specially developed together with DBIS, Goethe University, Frankfurt. AFE is also used by the Polish partner project „Finds of Ancient Coins from Territory Historically Associated with Poland“ at the University of Warsaw. AFE employs the concepts of the Linked Open Data project Nomisma.org, and is thus fully integrated into both external projects such as Online Coins of the Roman Empire (OCRE), and the iDAI resources Gazetteer and Zenon
