Nomisma.org

Nomisma.org is an international, collaborative project to provide stable digital representations of numismatic concepts according to the principles of Linked Open Data (LOD). These take the form of HTTP URIs that also provide access to reusable information about those concepts, along with links to other resources. The Nomisma.org community maintains a formalized RDF Ontology and a data model for encoding concepts, coins, typologies, hoards, and other types of numismatic objects as LOD.

The information made available by Nomisma.org has been provided by a wide community of scholars and institutions. All concepts published by Nomisma.org domain are openly accessible with a CC-BY license. See the Datasets page for further license statements for partner contributions to the Nomisma.org LOD ecosystem.

Get Involved

We are interested in contributions of open numismatic data. If you are a scholar willing to contribute expertise to expand the scope of Nomisma's coverage of concepts, please contact a relevant Working Group or the Scientific Committee to establish a new one.

Get Data

Nomisma.org concept and contributing partner Linked Open Data are available as bulk downloads. A SPARQL endpoint integrates these data and enables querying to answer complex research questions.

Conduct Research

Nomisma.org has built-in typological distribution and metrical analysis features, but most resesearch tools available in thematic projects listed in the About page. We plan to expand these graphical tools in Nomisma eventually, but the SPARQL examples provide a tutorial for asking complex research questions.

The following institutions have contributed data, specialist advice and/or financial support to the Nomisma project:
